Document Summary
Dna replication that protein interaction have 3 maint ypes. Large part of what we will talk about is how those proteisn interact with nucleic aicds to regulate the processes were talking about. Proteins binding to dna for a number of different reasons with differnet outcomes. Same forces that help nucltireci acids help ortuesn and nucleic acids. And most of theprotues that associate with dna are positively charged (histones) If u have a molecule negative charged it teldns to be in solution, surrounded by molecules that area dchared (even if its water, it wil be pollarly oriented) If other moelucels are ging to interact, it has to displace whats currently in that place. In all of that we have secondary suutrec eof dna with ajor and mino rgoroves. When protisn do interact with dna is, it is tring to look for a sewuence is reading that patter onf acceptors and donors of hydrogen ions that it can read.
