Document Summary
Science, technology and the environment (sc nats 1840a) - tuesday. Readings: 5. 2, 5. 3, 5. 4 genetics and natural selection. 22 amino acids (monomers) polymer called a polypeptide protein (one or more polypeptides) 5 nitrogen bases (pieces of monomers) 5 nucleotides (monomers) polynucleotide nucleic acids. Dna, rna (one or more polynucleotides) definition of traits manufacturing instructions . Realization of traits protein (one or more polypeptides) polymer called a polypeptide 22 amino. Traits: any single feature or quantifiable characteristic of an organism. Result of many biochemical processes involving specific proteins. Hair/eye/skin, colour, gender, ability to break down lactose, etc. Nucleus of each human cell contains 48 chromosomes which work in pairs to set traits. Each has a counterpart that carries information about the same traits (one from each parent); Slight variations in the genes on each member of a pair (different alleles) possible, corresponding to differences in the relevant trait (eg. brown eyes vs. blue eyes)
