Transcription Practice

Front

What is transcription in the context of genetics?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence, specifically messenger RNA (mRNA).

Front

What is the role of messenger RNA (mRNA)?

Back

mRNA serves as a template for protein synthesis, carrying genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.

Front

What is the complementary mRNA sequence for the DNA sequence TAC CGG CTG?

Back

AUG GCC GAC.

Front

What happens to mRNA after it is synthesized?

Back

mRNA leaves the nucleus and enters the cytoplasm for translation.

Front

Which enzyme is responsible for synthesizing mRNA during transcription?

Back

RNA polymerase.

Front

Where is DNA located in a eukaryotic cell?

Back

DNA is confined to the nucleus.

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 the function of transfer RNA (tRNA)?

Back

tRNA transports amino acids to the ribosome during protein synthesis, matching them to the appropriate codons on the mRNA.

Front

What is the function of ribosomal RNA (rRNA)?

Back

rRNA is a component of ribosomes, which are the sites of protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.
