Transcription

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA. It is the first step in gene expression.

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus of eukaryotic cells.

Front

Where does transcription occur in prokaryotic cells?

Back

Transcription occurs in the cytoplasm of prokaryotic cells.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic code from DNA to the ribosome for protein synthesis.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of synthesizing RNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What enzyme is responsible for transcription?

Back

RNA polymerase is the enzyme that synthesizes RNA during transcription.

Front

What are the three main stages of transcription?

Back

The three main stages of transcription are initiation, elongation, and termination.

Front

What is the significance of the promoter region in transcription?

Back

The promoter region is a specific sequence of DNA that signals the start of transcription and is where RNA polymerase binds.

Front

What is a transcription factor?

Back

Transcription factors are proteins that help regulate the transcription of specific genes by binding to nearby DNA.

Front

What is the difference between coding and non-coding RNA?

Back

Coding RNA (like mRNA) carries the information for protein synthesis, while non-coding RNA (like rRNA and tRNA) has roles in the translation process.
