American student, David - not his real name - explains why he chooses to buy illegal drugs on the so-called 'dark web'. You don't have to go in front of a street dealer, where there might be a risk of violence, he adds. And it is not just drugs which are available on this online black market. Fake passports, guns - even child pornography.
Genetic material is that substance which not only controls the inheritance of traits from one generation to the next but is also able to express its effect through the formation and functioning of the traits. Components of genetic material which control characters are called genes. Genes are located over chromosomes. In sexually reproducing organisms, an indiÂ­vidual receives one genome or one set of chromosomes (and hence genes) from male parent and a second genome or set of chromosomes from female parent.
Best Answer: DNA is the entire genetic material. A Chromosome is a strand of DNA containging the genes. A gene is a part of a chromosome which carries the information that is passed on to offspring.NA forms chromosomes which in cells form genetic codes (genes) in the nucleus, DNA is copied in cell division to make new chromosomes and some (very few) mutate and form new genes.
