Transcription in Protein Synthesis

These flashcards cover key terms and concepts related to the transcription phase of protein synthesis, including the role of RNA polymerase, promoter regions, and the steps involved.

What is the role of RNA polymerase in transcription?

RNA polymerase synthesizes mRNA from a DNA template.

Where does transcription occur in prokaryotes?

In prokaryotes, transcription occurs in the cytoplasm.

What is the function of the promoter region in transcription?

The promoter is a sequence of DNA that signals where RNA polymerase can attach to start transcription.

What is the 'TATAA box'?

The TATAA box is a specific sequence within the promoter that helps to recruit RNA polymerase.

What are transcription factors?

Proteins that bind to the promoter region and assist in the recruitment of RNA polymerase.

What happens to the DNA structure before transcription in eukaryotes?

The DNA must uncoil from histone proteins to allow RNA polymerase access.

What is the antisense strand of DNA?

The antisense strand is the strand that is transcribed into RNA.

What is the complementary base pair for adenine in RNA?

In RNA, adenine pairs with uracil.

Define 'terminator' in the context of transcription.

The terminator is a sequence in the DNA that signals the end of transcription.

What is the sequence of events in the transcription process?

Initiation, elongation, and termination.
