Front

Which enzyme joins the fragments on the lagging strand during DNA replication?

Back

Ligase.

Front

What enzyme relaxes supercoiling in front of the replication fork?

Back

Topoisomerase.

Front

What occurs during translation in protein synthesis?

Back

Information in mRNA is converted into a sequence of amino acids in a protein.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands.

Front

What is the significance of the 5' to 3' direction in DNA synthesis?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning nucleotides are added to the 3' end.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the role of ribosomes in translation?

Back

Ribosomes facilitate the decoding of mRNA into a polypeptide chain (protein).
