Document Summary
I experimentaloverview of identification replication and expression of genetic information. A identification of dna as genetic material unknown until late 19405. Deads bacteria mouse dies because dna is still. R bacteria into s bacteria intact and transforms purified s dna mouse dies and points toward dna being the genetic material of cells. Inheritance through semi conservative replication semi conservative replication one strand of parental dna is conserved in progeny dna. Model system e coli replicates every 20 minutes. Grew 5n bacteria in 4n media for one round replication. Hybriddna is medium heavyezlightjtzheavy obstacle of semiconservative replication there"s directionality 5 73. C howdoes the sequence information colinearity dna duprotein sequences in dna direct protein synthesis. Dna localized in nucleus protein synthesis located in cytoplasm. Solution mrna carries sequence information from nucleus to cytoplasm for protein synthesis. 2 chemistry 7 rna is composed of nucleotides proteins are composed of amino acids. Solution trna serve as adaptors between mrna and amino acids.
