Gene and Finny are two character in the John Knowles novel, A Separate Peace. What is the relationship between chromosomes DNA and genes? DNA-->. DNA, or deoxyribonucleic acid, is a large molecule or polymer that consists of monomers called nucleotides. The function of DNA is to store hereditary. Finny Varghese We show that fusion chromosomes have retained the ancestral chromosome segments and Further studies are warranted to elucidate the temporal and causal relationships between gut microbiota and PD and the .. prophage genes and restriction modification systems (mechanisms of DNA exchange.

There are 20 amino acids. The proteins that genes make ultimately join together to build cells, tissues, organs, and, finally, whole organisms. Music, of course, depends on repetition, too. The scale holds subunits tones repeated in infinite variations.

When Ohno began analyzing music, he had no formal training. He knew the basic positions of the notes on the staff; that was all. Other Ohno experiments have resulted in pieces that sound as if they span much of the spectrum of western music, from the Baroque, Classical, and Romantic periods to the astringent dissonances of Igor Stravinsky.

With people like Chopin and Dvorak, the repetition is less obvious, just as it is in our modern genes.

They often run into hundreds of thousands of subunits and the work is very boring. Why do we like certain melodies?

Ohno is tantalized by the idea that great composers write from their genes. If you could have sat next to Beethoven while he fooled around at the piano, the music would have sounded like Beethoven, no one else. Moreover, musical ability is one of the first detectable talents in the young. It occurs much too early to hinge on environmental factors.

Music, thus, is primal. Similarly, says Ohno, all of us carry in our cells the remnant genes of evolution; the genes our ancestors needed eons ago to survive as finny and furry creatures. An animal embryo, during the early stages of development, seems to repeat the adult stages of lower animals from which it descended. A human embryo, for instance, has gills like a fish for a while. When a fetus sets out to make a kidney, its genes first construct a fish kidney, then a frog kidney, and finally a human kidney.

But every so often, the Russians will catch a whale that has legs sticking out from the body. The ungulates, the two-hooved animals, had the horns. But there are two modern horses on record that had little horns growing out of their heads. One of them--Belmar, was his name--even won the Belmont Stakes and the Preakness in The other was a gelding, Marooned, who was popular during the Depression. At the time, kings collected deformed people as curiosities.

He was completely covered with hair. Both girls were as completely covered with hair, too. This meant the hair gene was dominant, and each child stood a chance of inheriting it. Wisdom teeth, though, are utterly useless and evolved by mistake. Before the era of dental surgery and antibiotics, they killed many people.

But the surgeons just snip them off, and we never hear about them. For most of the enzymes we make, we have the same set of genes as fish. Scientists also know that our very earliest ancestor--the first cell capable of copying itself--was born sometime between the creation of the earth 4.

But a DNA subunit cannot do anything by itself. Somehow the basic sequence must get translated into the amino acid sequence of a protein. Then we can start life, eh?

DNA, genes and chromosomes

How did this happen? Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: The DNA double helix showing base pairs The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.

There are four types of base: These bases link in a very specific way: A always pairs with T, and C always pairs with G. The DNA molecule has two important properties. It can make copies of itself. If you pull the two strands apart, each can be used to make the other one and a new DNA molecule.

It can carry information. The order of the bases along a strand is a code - a code for making proteins. Genes A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood. Genes are the basic unit of genetics. Human beings have 20, to 25, genes.

These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.
