BIOL 3110 Lecture Notes - Lecture 1: Dnaa, Thymidine, Dna Polymerase Iii Holoenzyme
Document Summary
Gregor mendel from one generation to the next: transmission genetics the mathematical patterns that occur as alleles pass, used math equations to come up with mendel laws. Isolated the first crude dna discovered nitrogen, phosphorus ratio. Phoebus levene: biochemist who studied the chemical structure of nucleic acids found that. Hermann muller: demonstrated that x-rays could induce a frequent inactivation of genes called mutation now, genes can be influenced by x-rays phenotype. Fred griffith: proposed that some (cid:498)unknown molecule(cid:499) had transformed the harmless r strain of streptococcus pneumoniae to the virulent s strain the molecule was dna. Dna structure: people had been looking at bases before levene, dogma was that all bases are present in equal proportions (1909-1940s) Information: the molecule contains information expressed in the sequence of the nucleotides: the sequences are transcribed into rna to release their information.
