Which of the following bind(s) to DNA enhancer regions?
A
Ribosomes
B
Transcription factors
C
DNA polymerase
D
tRNA molecules
Verified step by step guidance1
Step 1: Understand what DNA enhancer regions are. Enhancers are specific DNA sequences that increase the transcription of particular genes by serving as binding sites for certain proteins.
Step 2: Identify the types of molecules listed: ribosomes, transcription factors, DNA polymerase, and tRNA molecules, and recall their primary functions in the cell.
Step 3: Recall that ribosomes are involved in protein synthesis by translating mRNA, so they do not bind to DNA enhancer regions.
Step 4: Recognize that DNA polymerase is an enzyme responsible for DNA replication and does not bind to enhancer regions to regulate transcription.
Step 5: Understand that transcription factors are proteins that specifically bind to enhancer regions to regulate gene expression by facilitating or inhibiting the recruitment of RNA polymerase.
