BIO 325 Chapter Notes - Chapter 11-12: Pyrimidine, Purine, Thymine
Document Summary
Control of genetic info; sensitive to toothed conditions like enzymes, environmental signals and rna. Sequence of amino acids determines structure and chemical properties. Beadle and tatum experiment replication - -doesn"t lose genetic info. Making exact copies of dna by dna dependent dna polymerase transcription - -doesn"t lose genetic info. Creating rna copy of dna message with dna dependent rna polymerase translation - -does lose genetic info. Control biochemical processes as enzymes translation - which dna process results in a loss of information? viruses - what reproduces through reverse transcription or replicase activity reverse transcription - -mediated by rna dependent dna polymerase. Makes a dna copy of a single strand of rna. This dna strand is then inserted into a host chromosome replicase activity - allows some viruses to directly replicated with rna dependent. Rna polymerase prokaryotes - -transcription and translation simultaneously occur in cytoplasm.
