Front

Who built the model of DNA that helped scientists understand how DNA could replicate?

Back

James Watson and Francis Crick

Front

What enzyme relaxes supercoiling in front of the replication fork during DNA replication?

Back

Topoisomerase

Front

What is the end result of DNA replication?

Back

2 semi-conservative strands of DNA

Front

What is the function of helicase in DNA replication?

Back

Helicase unzips the DNA to prepare for replication.

Front

Which strand is formed continuously during DNA replication?

Back

Leading strand

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides.

Front

What are the building blocks of DNA?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is semi-conservative replication?

Back

Each new DNA molecule consists of one old strand and one new strand.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.
