Front

Why is topoisomerase important in DNA replication?

Back

Topoisomerase is important for stopping the DNA from supercoiling.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.

Front

What is the function of primase in DNA replication?

Back

Primase synthesizes a short RNA primer to initiate DNA synthesis.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is the significance of the 5' and 3' ends of DNA?

Back

They indicate the directionality of the DNA strands, crucial for replication.
