In addition, when proteins are being made, the double helix unwinds to allow a single strand of DNA to serve as a template. This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions to the cell's protein-making machinery.
Each strand of DNA is a chromosome. we have 23 pairs of chromosomes, so 23 pairs of DNA strands. (23 from each parent) inside these DNA strands are stretches that code for a particular trait. these are called the genes. one trait can have many genes, or there can be one gene for one trait. but inside a DNA strand there are many many genes.
