Document Summary

Fall 2018: l, double helix, chernoff- looked at dna bases was always kinda the same. Discovered" the shape of dna: double helix, dna replication, since a always binds with t and c with g: one strand specifies the strand of the other, dna is locally denatured (unzipped) the dna polymerase helps the nucleotides. Match" with the parent strand: medion and hahl (1958, grew e. coli in 15n (heavy nitrogen, discovered that dna is semiconservative where the heavy strands and. Errors do occur: central dogma, dna transcribed mrna translated protein, transcription, uses rna polymerase. Acat (dna) ugua (mrna transcript: translation. 20 aa but only 4 nucleotides: uses 3 bp to form a codon, proline is coded for by ccc and ccu and cca dna is degenerate. ***g3 has same gamete ratios!!!: genetic equilibrium. 0. 16 dd: hardy -weinberg law, allele frequency always stays the same, after one generation of random mating, genotype frequency will remain a.
