What is transcription in biology?

Back

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

What does A transcribe to in RNA?

Back

A transcribes to U (Uracil) in RNA.

Front

What does T transcribe to in RNA?

Back

T transcribes to A (Adenine) in RNA.

Front

What does C transcribe to in RNA?

Back

C transcribes to G (Guanine) in RNA.

Front

What does G transcribe to in RNA?

Back

G transcribes to C (Cytosine) in RNA.

Front

What is the role of RNA polymerase in transcription?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine (T), while RNA is single-stranded and contains uracil (U) instead of thymine.

Front

What are the three main types of RNA?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is mRNA's function?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is tRNA's role in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.
