31. The cI protein and the Cro repressor are important elements for this control. 32. A quintessential example of this negative regulation is Nur, nickel binding repressor . 33. Bashar the computer geek versus Hafez the repressor . 34. The non-specific sequences decrease the amount of available repressor in the cell. 35. The Nanos protein is a translational repressor protein. 36. DNA methylation is a powerful transcriptional repressor , at least in CpG dense contexts. 37. It can also act as a transcriptional repressor . 38. It functions as a transcriptional repressor , and expression of E1A inhibits this repression. 39. Repression of gene expression works via binding of repressor molecules to the two operators. 40. The unlinked " galR " gene encodes the repressor for this system.
