Deoxyribonucleic acid (DNA) cotains genetic information of an organism that is unique for each organism. The entire cellular DNA of any organism, bacteria, plant or animal is known as its genome. Each DNA present in a single person can have variations, but if we sequence the whole genome , it would be unique.
Likewise, what is meant by selfish DNA?
Selfish DNA is a term for sequences of DNA that have two distinct properties: the DNA sequence spreads by forming additional copies of itself within the genome; and. it makes no specific contribution to the reproductive success of its host organism. (It may or may not have significant negative effects.)
What is a satellite on a chromosome?
A satellite chromosome or SAT chromosome has a chromosome segment that is separated from the main body of the chromosome by such a secondary constriction. The term is due to Sergei Navashin, in 1912. The satellite at metaphase appears to be attached to the rest of the body of chromosomes by a thread of chromatin.
What is Minisatellites?
A minisatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 10–60 base pairs) are typically repeated 5-50 times. Minisatellites occur at more than 1,000 locations in the human genome and they are notable for their high mutation rate and high diversity in the population.
