AAC Transcription and Translation

Multiple Choice

Why is the process of transcription and translation significant in living organisms?

• It allows cells to replicate their DNA for cell division.

• It enables the conversion of genetic information into functional proteins.

• It helps in the breakdown of nutrients for energy.

• It is responsible for the elimination of waste products from the cell.

Multiple Select

Which of the following statements about RNA polymerase is/are correct?

• It binds to the promoter region on DNA.

• It separates the DNA strands during transcription.

• It adds nucleotides to the growing RNA strand.

• It splices exons together.
