Transcription

What is the role of mRNA in transcription?

Back

mRNA (messenger RNA) carries the genetic information from DNA out of the nucleus to the ribosome for protein synthesis.

Front

What are the base pairing rules for RNA during transcription?

Back

In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus.

Front

What is the structure of RNA compared to DNA?

Back

RNA is single-stranded, while DNA is double-stranded.

Front

How many nucleotides are needed to code for one amino acid?

Back

Three nucleotides (a codon) are needed to code for one amino acid.

Front

What is the function of RNA polymerase in transcription?

Back

RNA polymerase is the enzyme that synthesizes RNA from the DNA template during transcription.

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 where RNA polymerase binds.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the difference between transcription and translation?

Back

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

Front

What happens to mRNA after transcription is complete?

Back

After transcription, mRNA undergoes processing (capping, polyadenylation, and splicing) before it is transported to the ribosome.
