Nitrogenous base

Front

What is the circled portion of the DNA strand called?

Back

Nucleotide

Front

When is DNA replicated?

Back

Before mitosis

Front

Why does DNA need to be replicated before the cell divides?

Back

So that every new cell has a complete set of chromosomes (DNA).

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, and nitrogenous base.

Front

What is the role of DNA helicase in replication?

Back

It unwinds the DNA double helix.

Front

What is the function of DNA polymerase?

Back

It synthesizes new DNA strands by adding nucleotides.

Front

What is the difference between leading and lagging strands during DNA replication?

Back

Leading strand is synthesized continuously, while lagging strand is synthesized in fragments.
