By Benna Crawford Genetics is the science of what makes you, you. Genetics explains why you have red hair like your dad, a wide smile like your mom, and long skinny legs like your Aunt Helen. You need a powerful microscope to peek inside a human cell to unlock the secret formula that turns a bunch of proteins into a unique person. Structure and Function of DNA Ever wonder why your twin brother is a slow shuffler with a wicked pitching arm while you can’t hit the broad side of a barn, but you can run like the wind? Blame it on three little letters that have a huge effect on your looks, talents and even temperament. Those letters are DNA, and they stand for a long scientific name deoxyribonucleic acid. Here’s how you say it: DNA is a molecule that contains the information to make proteins. Proteins, along with water, sugars, fats and DNA, constitute your cells and create the chemicals to make your body function.
The Structure and Function of DNA
By Yevgeniy Grigoryev The other day I was having a conversation with a friend of mine who had some background in computer science. The conversation shifted towards my research and the following question came up: What is the amount of digital information stored in a human genome? I started searching in the deep dark corners of my brain, but I realized that I simply did not know the answer. So I decided to do the math to estimate how much information is stored in our genome.
DNA stands for deoxyribonucleic acid and is one of the two types of nucleic acid found in our cells. The name describes what the molecule is. DNA is beautifully intricate and works in complicated mechanisms to control the cell.
Regions of the brain have differing amounts and reliance on these types of neurons, and are affected accordingly. The remaining variation is attributed to environment and other genes that modify the mechanism of HD. In some cases the onset may be so late that symptoms are never noticed. Inheritance is independent of gender, and the phenotype does not skip generations. Huntington’s disease has autosomal dominant inheritance, meaning that an affected individual typically inherits one copy of the gene with an expanded trinucleotide repeat the mutant allele from an affected parent.
This probability is sex-independent. Individuals with both genes affected are rare. For some time HD was thought to be the only disease for which possession of a second mutated gene did not affect symptoms and progression,  but it has since been found that it can affect the phenotype and the rate of progression. Early damage is most evident in the striatum , but as the disease progresses, other areas of the brain are also more conspicuously affected.
Early symptoms are attributable to functions of the striatum and its cortical connections—namely control over movement, mood and higher cognitive function. Huntingtin HTT is expressed in all cells. The highest concentrations are found in the brain and testes , with moderate amounts in the liver , heart , and lungs. It interacts with proteins which are involved in transcription, cell signaling , and intracellular transporting.
Caspase , an enzyme which plays a role in catalyzing apoptosis, is thought to be activated by the mutated gene through damaging the ubiquitin-protease system.

Then all hell broke loose. Neither has the field of paleontology. Two years ago, Schweitzer gazed through a microscope in her laboratory at North Carolina State University and saw lifelike tissue that had no business inhabiting a fossilized dinosaur skeleton: By all the rules of paleontology, such traces of life should have long since drained from the bones. It’s a matter of faith among scientists that soft tissue can survive at most for a few tens of thousands of years, not the 65 million since T.

CC0 Public Domain Sick and tired of looking for love? There’s now a website that does it for you, using your DNA. What determines who we fall in love with? Is it a matter of circumstance? Is it written in the stars? Or is our romantic compass something that’s ingrained into our very being? What if the type of people we’re into is determined by the very same internal code that dictates whether or not we like coriander?
That’s right, romance might be written in our DNA. Thankfully, there’s now a service that can help you decipher your As, Ts, Gs and Cs and get to the bottom of this love thing once and for all. The theory is that your body produces chemical signals, as determined by your DNA. When a potential partner detects these signals supposedly by smelling them , it creates ‘chemistry’—an innate sense of attraction that can’t be credited to your height, lack of debt or ability to play bass guitar.

Sarah Lee for the Guardian At first, I’m not even sure how best to frame the question in order to secure my wife’s participation. But here’s the gist of the idea: Suitable partners can literally sniff each other out, finding an optimal genetic other half using their noses. The basis for this notion is the so-called smelly T-shirt experiment, first performed by a Swiss zoologist called Claus Wedekind in He analysed a particular bit of the DNA of a group of students, looking specifically at the major histocompatibility genes MHC.
The scientists found that exposure to paracetamol or ibuprofen triggers mechanisms in the cell that make changes in the structure of DNA, called epigenetic marks.
By Tara Kunesh M. Plant and animal cells have a surprising amount in common. Although plants and animals are usually seen as two very separate forms of life, this is not strictly true. When studied at the cellular level, the student will discover that the basic building blocks of both plant and animal life are unexpectedly similar. Animal Cell Basics Like all organisms, animals are built from cells. There are many different types of animal cells, each with a job and a purpose.
However, there are some general characteristics that all cells share. Both the cells of animals and plants and fungi are what is known as eukaryotic.

Tweet NaturalNews If you believe that you are at the mercy of your genetic code, great news, you’re not. According to the science of epigenetics the study of how environmental factors outside of DNA influence changes in gene expression , stem cells and even DNA can be altered through magnetic fields, heart coherence, positive mental states and intention.
Top scientists around the world agree: Curbing the genetic victim mentality The DNA we are born with is not the sole determinant for our health and well-being. Stem cell biologist Bruce Lipton, Ph. This kind of belief system provides a visual picture of people being victims: If the genes control our life function, then our lives are being controlled by things outside of our ability to change them.
This leads to victimization that the illnesses and diseases that run in families are propagated through the passing of genes associated with those attributes. Laboratory evidence shows this is not true. Ventura has shown through lab testing that the DNA of stem cells can be altered using magnetic field frequencies. You’re reprogramming somehow backward with these cells to an uncertain state in which any kind of decision is somehow possible; even the decision to become virtually any kind of cell of the organism.
And just think about the tremendous potential of this discovery. After two decades of study, the researchers discovered factors like love and appreciation or anxiety and anger also influence a person’s blueprint.

Initial analysis on the DNA reveals a complex and confusing interbreeding of species which took place in our ancient past, and scientists are still scratching their heads over exactly what kind of species the DNA belonged to. Until now, it has not been possible to study the DNA of these unique hominins, however, scientists from the Max Planck Institute for Evolutionary Anthropology were able to use novel techniques to extract the DNA and have determined an almost complete mitochondrial genome sequence of a , year-old representative of the Homo genus.
The researchers then compared the DNA with Neanderthals, Denisovans, present-day humans and apes, and found that the individual shared a common ancestor with the Denisovans, a relatively newfound relative of humans who are thought to have lived in the vast expanse from Siberia to Southeast Asia.

Highlighted are the nucleobases green and the ribose-phosphate backbone blue. Note that this is a single strand of RNA that folds back upon itself. The vast majority of the time, these encounters yield nothing, but a special few sustain life as we know it. Faruck Morcos and Zachary Campbell at The University of Texas at Dallas are pursuing what differentiates a fruitful encounter from a dud—a mystery with long odds similar to finding a soul mate among the metaphorical millions of fish in the sea.
Their ultimate goal is to prevent the relationships that become toxic and result in disease. A new study, published in Nature Communications, shows the researchers’ progress in understanding how molecules called RNA pair with intended protein partners. The researchers hope that they eventually will be able to predict and manipulate these partnerships that have been carved through millions of years of evolution.

The name describes what the molecule is. DNA is beautifully intricate and works in complicated mechanisms to control the cell. As a teacher, I am a strong believer that you can teach anyone, anything. The younger the student, the more likely they are to retain it. So, let us take a look at how you would explain DNA to a six-year-old. DNA is a nucleic acid i.
Still, because mitochondrial DNA is passed down from mother to child, it leaves out the story of the father’s DNA. The nuclear genome, which contains DNA from both parents, is far more informative.
Genetic evidence for the Flood – a human population bottleneck matching Noah’s Flood Genesis – is glaringly obvious when our DNA is examined truthfully and logically. Plus going back further – the genetic proof for the first humans, Adam and Eve. Introduction There’s an old B-grade psychological horror film where a babysitter, babysitting at the client’s home late at night, continually receives threatening calls from a stalker on the house phone.
She calls the police who promise to trace the call if she keeps the caller on the phone line long enough. She’s extremely frightened and arms herself, and then receives a final call from the madman. Please read on, and decide for yourself if there’s a call to your conscience from your very own hereditary blueprint. So the Y chromosome is passed on only from father to son.
Mitochondria — these are little compartments inside each of our cells which house the components to produce the cell’s energy. Since only the mitochondria contained in the fertilized egg are used at conception, mtDNA is only inherited from the mother. Males are therefore dead-ends for mtDNA. When DNA which contains the sex chromosomes and mtDNA are passed down to offspring, mutations copying errors can and do occur.
There is very good evidence to support this. Genesis states that eight people were on the Ark:
