E)leucine zippers

Question

Quizplus · Accepted Answer

Cis-acting regulatory sequences are regulatory regions of a eukaryotic gene that act only on one copy of the chromosome, and are present in all regulatory regions. Zinc fingers, homeodomains, leucine zippers, and trans-acting regulatory sequences are specific DNA-binding domains present in transcription factors and other regulatory proteins. However, they do not act exclusively on one copy of the chromosome and are not found in all regulatory regions.
