AP Bio Insta-Review Topic 6.6*: Gene Regulation & Cell Special

Front

What is siRNA?

Back

Small RNA strand that binds to mRNA to inhibit translation.

Front

What is the function of the promoter?

Back

Site of RNA polymerase binding for transcription.

Front

What are siRNA?

Back

Small interfering RNA.

Front

What is the function of RNA polymerase?

Back

Binds to DNA to synthesize an RNA transcript.

Front

What is the role of RNA polymerase in transcription?

Back

Synthesize RNA transcript.

Front

What is gene regulation?

Back

The process of turning genes on and off to control gene expression.

Front

What are transcription factors?

Back

Proteins that help regulate the transcription of specific genes.

Front

What is the difference between enhancers and silencers?

Back

Enhancers increase transcription, while silencers decrease transcription.

Front

What is the role of mRNA in gene expression?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the significance of introns and exons?

Back

Introns are non-coding regions removed during RNA processing, while exons are coding regions that remain.
