benjaminshr Posted November 13, 2009 Share Posted November 13, 2009 Every one of us, except identical twins or clones, has a unique set of DNA, or a genome, which in part is what makes us separate individuals. Inside each of our cells’ nuclei, we have 23 pairs of chromosomes, and one in each pair is inherited from one of our parents. The thread-like chromosomes contain all our genetic information. DNA (deoxyribonucleic acid) molecules make up most of a chromosome and are the genetic material for all cellular organisms and most viruses. They act as the message carriers of chemical sequences governing the production of proteins. Such patterns are the genes, and all together they make up the blueprint of life.

georgeskohler Posted November 15, 2009 Share Posted November 15, 2009 I agree.... well, germ cells have only one set of chromosomes, but yeah. It's also cool that small regulatory RNAs regulate gene expression and....other stuff. And then there are cells without nuclei like platelets, and Schwann cells which wrap around axons and that's cool....but I guess irrelevant...what would be a relevant response?

cameron marical Posted November 15, 2009 Share Posted November 15, 2009 Plasmids are also an addition to uniquety in genetic systems. Link to comment Share on other sites More sharing options...
