Document Summary
Chapter 5 and 6: dna replication, repair and recombination 1. In looser euchromatin conformation when gene expression is taking place. Slide 3: hershey and chase demonstrated definitively that genes were made of. Dna: one set of bacteriophage t2 were incubated with 32(p) for uptake into. Dna, one set of viruses incubated with 35(s) for uptake into protein: only the dna had entered the cell - the 35(s) proteins had remained in the incubation mix, together with the vacant (no nucleic acid) viral heads. Chapter 5 and 6: dna replication, repair and recombination 2: this helps to make the energetically favorable conformation of the dna helix, transcription factors: proteins that turn gene expression on and off. In order to get access to the dna they bond to the major groove because that is the biggest area they can get into without impacting the structure of the dna. Chapter 5 and 6: dna replication, repair and recombination 3.
