Slide 2 of 109
Listed above are the major
categories of discussion for this lecture.
- DNA (Deoxyribonucleic acid)
- is the long molecule that codes for the information
required to produce a living organism. DNA exists in the form of a linear
polymer of nucleotides ( adenine, guanine, thymine, or cytosine bound to a
phosphorylated sugar - deoxyribose). Under normal circumstances, two strands
of DNA are twisted together into the double helix. In eukaryotes (organisms
whose cells contain a nucleus) DNA is packaged into chromosomes.
- mtDNA ( Mitochondrial DNA)
- A small piece of DNA that codes
for a small number of proteins within the energy-producing
sub-cellular organelle known as the mitochondrion.
- A species of hominid (Homo neandertalensis) that lived 150,000-30,000 years ago. Formerly
known as Neanderthals.
- The ability to walk upright on two legs.
