How do chromosomes work

WebA chromosome is made of a very long strand of DNA and contains many genes (hundreds to thousands). The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus). In addition to DNA, chromosomes contain other chemical components that influence gene function. Pairing WebHow DNA transcription works. (1) In initiation, RNA polymerase binds to a promoter sequence at the start of a gene and (2) unwinds the double helix to expose the anti-sense strand. (3) In elongation, RNA polymerase reads the DNA template one base at a time, constructing a pre-mRNA transcript from free-floating nucleotides.
