Gene Regulation and Mutation

The noncoding sequence of DNA located within the promoter where RNA polymerase will bind is called the ________.

A type of control element that acts with transcription factors to promote initiation may be perceived as a distal control element. This control element is called a(n):

The function of siRNAs is to:

• play a role in RNAi

• contribute to euchromatin formation

• degrade mature RNA

• contribute to forming mutations in the promoter sequence

Cancerous genes that have undergone some type of transformation from their normal counterparts through mutations are called ________.
