Front

What does semiconservative replication mean in DNA replication?

Back

One strand is kept as a template to build the other new strand.

Front

What is the first step in DNA replication?

Back

The first step in DNA replication is to unwind and unzip the two strands.

Front

When is DNA copied?

Back

DNA is copied during cell division.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the three components of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme that adds new nucleotides to the growing DNA strand during replication.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate DNA replication and the preservation of genetic information.
