the Myth of Race

Uploaded on Jan 31, 2008 One of the leading authorities on race and science, Troy Duster discusses how the understanding of race is being reshaped by the genomics revolution. Sometimes unintentionally and sometimes not so innocently, genomics may be generating a new and more sophisticated racism, not so different from the eugenics-based and criminological racism […]

Adenine

Adenine /ˈædᵻnᵻn/ (A, Ade) is a nucleobase (a purine derivative). Its derivatives have a variety of roles in biochemistry includingcellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD). It also has functions in protein synthesis and as a chemical component […]

purine

A purine is a heterocyclic aromatic organic compound. It consists of a pyrimidine ring fused to an imidazole ring. Purines, which include substituted purines and their tautomers, are the most widely occurring nitrogen-containing heterocycle in nature.[1] Purines and pyrimidines make up the two groups of nitrogenous bases, including the two groups of nucleotide bases. Two […]

Deoxyribonucleic acid

Deoxyribonucleic acid (i/diˈɒksiˌraɪboʊnjʊˌkliːɪk, –ˌkleɪɪk/;[1]DNA) is a molecule that carries most of the geneticinstructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromoleculesessential for all known forms of life. Most DNA molecules consist of […]

mitochondrial DNA

One tiny piece of our DNA is inherited only down the female line. It is called mitochondrial DNA because it is held as a unique circular strand in small tubular packets known as mitochondria that function rather like batteries within the cell cytoplasm. Some molecular biologists say that, aeons ago, the mitochondrion was a free-living […]

memories in DNA

Parental olfactory experience influences behavior and neural structure in subsequent generations Brian G Dias & Kerry J Ressler Full text PDF Abstract Using olfactory molecular specificity, we examined the inheritance of parental traumatic exposure, a phenomenon that has been frequently observed, but not understood. We subjected F0 mice to odor fear conditioning before conception and found […]

Body and mind

After you—even nervously—assume a confident pose for a meaningful amount of time (studies tested 2 minutes, which was significant enough as you’ll see), your brain will increase your testosterone levels and decrease your cortisol levels. I call this combination the “confidence cocktail,” as lower cortisol makes you calmer and higher testosterone increases your aggressiveness and willingness to […]

Neanderthal DNA

Uploaded on Jul 4, 2011 Neanderthal DNA has been proven transferred to all Non-Indigenous Africans, from Neanderthal male to Homo Sapien female, most likely in Arabia/Middle East early in our migration just outside of Africa. Neanderthals are not extinct, as they live on in all non-Africans, providing 10 genomes that indigenous Africans lack Advertisements
