Question
Chapter 10, Problem 2A
Summary Introduction
Introduction:
Bacterial SMC proteins are the structure maintenance complex proteins which provide the structural framework to the condensed chromatin so that they are held together during the division of the cell. These proteins are similar to the eukaryotic proteins like cohesin and condensin.
