DNA Replication

Front

What is the shape of DNA?

Back

Double helix

Front

Why is DNA replication described as 'semi-conservative'?

Back

The old strand is 'conserved' and used to make the new strands.

Front

What are the gaps between the newly synthesized DNA on the lagging strand called?

Back

Okazaki fragments

Front

What percent of each new strand of DNA is derived from the old strand?

Back

Half of each new DNA is the old DNA.

Front

What enzyme synthesizes an RNA primer for DNA polymerase?

Back

Primase

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides to the growing chain.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix structure of DNA.

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 found in DNA?

Back

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

Front

How do the nitrogenous bases pair in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.
