How Life is Organized
The amino acids and proteins comprise cells that are each specialized to carry out different functions in any living organism. The “roadmap” that determines what a particular cell does in this scheme is encoded in each cell’s deoxyribonucleic acid (DNA). Here is the chemistry behind that:
· Nucleic Acid – “Either of two complex organic molecules (DNA and RNA), consisting of many nucleotides linked in a long chain, and present in all living cells.” “The molecule consists of linked units called nucleotides, each containing a 5 carbon sugar (ribose for RNA, deoxyribose for DNA), a purine or pyrimidine base (adenine, guanine, cytosine, thymine, or uracil), and phosphoric acid.”
· Deoxyribonucleic Acid ...
