Document Summary

Evolution a change in gene frequency from one generation to the next: macroevolution, microevolution. Chromosome a long strand of dna: a gene is a segment of the chromosome; therefore it is made of/consists of dna. Dna transmits information from one generation to the next: passes genetic mutation, consists of . Hydrogen bond: nucleotide one phosphate, one sugar, and one base, t-a, c-g. Protein synthesis: enzymes, transporting agents, structural support, during protein synthesis. Chromosomes: 23 pairs, autosomal 22, sex chromosomes. Male: xy: female all 23 pairs are homologous. Gregor mendel: male 22 pairs are homologous but xy is hemizygous, homozygote: aa, aa, heterozygote: aa, locus: address for allele. Gene frequency: evolution is defined as a change in gene frequency over time, breeding populations, gene pool. No random processes (drift: frequency of b = p, frequency of b = p. Polymorphisms: a discrete genetic trait in which there are at least two alleles at the locus.
