Chapter 11 Regulation of Gene Expression
... Despite the simplified way in which we often represent DNA in figures such as those in this chapter, DNA is almost never entirely separated from chromatin proteins during interphase, and histones remain associated with the DNA at many positions along the molecule even during transcription. The rate ...

... step in protein synthesis. Genes are made of DNA and contain the codes for making proteins. Since DNA is unable to leave the nucleus, RNA Pol II makes an mRNA copy that can leave the nucleus. Ribosomes then attach to and read the mRNA. They synthesize a protein by joining amino acids in the co ...
