DNA Transcription

Front

What is DNA transcription?

Back

The process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What is a gene?

Back

A section of DNA that codes for a specific protein.

Front

What is the primary function of DNA?

Back

To store genetic information.

Front

What is mRNA?

Back

Messenger RNA, a type of RNA that carries genetic information from DNA to the ribosome for protein synthesis.

Front

What happens to mRNA after it is synthesized?

Back

It leaves the nucleus to be translated into a protein.

Front

What is the difference between DNA replication and transcription?

Back

DNA replication copies the entire DNA molecule, while transcription copies only specific genes into 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 are the three main types of RNA?

Back

mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the significance of the promoter region in a gene?

Back

The promoter region is a sequence of DNA that initiates transcription by providing a binding site for RNA polymerase.

Front

What is a codon?

Back

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