Document Summary
Homology - relatedness in structure, function, or aa sequence, most easily explained by two genes or organisms sharing the same common ancestor, small biomolecules that are found in all living things. Glucose, glycerol: proteins = large macromolecules structure and enzymatic function, archeal single-celled prokaryote, plant, animal, slight differences in amino acid sequences. Tata binding proteins from three species remarkably similar in their 3d: same relation . Similar sequences and structure = conserved between species. Oxygen atmosphere forming s m s i n a g r o c i p o c s o r c a. Explanation for homologous proteins, dna, genetic code, etc: structure = function, the structure of a molecule determines its function. Dna: the structure-function hypothesis function, how does dna exemplify the connection between structure and, dna is composed of 4 nucleic acid bases, the bases are attached to 5-membered rings. Rings are connected by phosphates: two chains bond to each other h-bonding.
