What is transcription?

Back

Transcription is the process by which the genetic code of DNA is copied into a strand of RNA.

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from the DNA in the nucleus to the ribosome, where proteins are synthesized.

Front

What are introns?

Back

Introns are non-coding segments of mRNA that are removed during the process of RNA splicing before translation.

Front

What are exons?

Back

Exons are the coding segments of mRNA that are retained and translated into proteins.

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

What is the complementary RNA sequence for the DNA sequence AAA TTT?

Back

The complementary RNA sequence is UUU AAA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

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 enzyme is responsible for synthesizing RNA during transcription?

Back

RNA polymerase is the enzyme responsible for synthesizing RNA from the DNA template during transcription.
