Document Summary

Ant100- lecture 2: principles of evolution: understand microevolution, genetic basis of inheritance and bio evolution, pop genetics, natural selection, adaptation, understand macroevolution, what"s cladistics, how to read a cladogram. Modern synthesis of evolution: how evolution works at level of phenotypes, genes and populations, macroevolution, microevolution, dna-> rna= protien. Chromosomes: paired rod-shaped structures in cell nucleus containing genes that transmit traits from generation-generation, made of winded strand of dna. Linear sequence of amino acids; building blocks of cell: each protein has specific function determined by blueprint stored in dna, e. g. Catalysis of all biochemical reaction done by enzymes which contains protein (digestion) and more: toxic if organism doesn"t have enzymes to help break down food. Codons: genetic info encoded in sequence of three nucleotides termed codons, four nucleotides of rna adenine, guanine cytosine, and uracil which replaces thymine in. May increased dna stability and improved efficiency of. Dna replication: prevent copy error, if wrong kind of protein form= dangerous.
