Document Summary
Dna: macromolecule made of nucleic acids, repository of the genetic code, source of genetic information. Proteins: macromolecules made of amino acids, amino acid sequence determined by dna sequence, some enzymes are rnas, so not all enzymes are proteins. Biological systems: network of interactions between molecules or groups of cells, accomplish coordinated functions. The biological information in dna generates an enormous diversity of living organisms. There is a variety in the dna between different organisms. Small changes lead to a variety of bigger picture changes. Complementary base pairs are a key feature of the dna molecule. Dna is comprised of four nitrogenous bases. [guanine (g), adenine (a), cytosine (c), and thymine (t)], a deoxyribose, and a phosphate. G c and a t hydrogen bonds between each strand of the double helix. The two strands of the double helix are in opposite orientation. The information in dna is one-dimensional and is digital.
