The following is a map of four genes on a chromosome. Between which two genes would you expect the highest frequency of recombination (crossing over occurring)?   Doc6.docx

Imagine that you are studying the control of beta-globin gene’s expression in immature red blood cells (mature red blood cells contain beta-globin protein but lack a nucleus and therefore the beta-globin gene). If you deleted a sequence of DNA outside the protein-coding region of the beta-globin gene and its promoter, and found that this decreased the rate of transcription, the deleted sequence likely functioned as a (n) _____.

Name 17 [17], Name 18 [18]

In gene regulation, negative control (turning a gene off) is exerted by a(n)
