Document Summary
In a genome analysis of eukaryotes, it was found that there were archaea loci cells. The basic unit of biological information: a segment of dna encoding a protein o. A discrete region of a chromosome encoding a protein or rna. Human mitochondrial genome is circular, in tact, and present in many copies per cell (polyploidy) o o. Simple example of a gene: cox1 = 1,542 bp long (in human mitochondrial genome = 16. 6 kb) Encodes for cytochrome c oxidase subunit 1 (a protein found in a multi-protein complex known as cytochrome c oxidase) o. Rna polymerase makes cox1 which makes other genes o o o. The same gene can be present in different species. What happens when you express this gene: make a mrna that contains all the introns o. Splice those intron to obtain a mature processed transcript that is more useful via splicing introns: obtain transcript for the same proteins.
