Unit 1.1 Review | DNA Replication

Front

Why does DNA need to be replicated?

Back

So each cell that results from cell division has the exact DNA.

Front

What is the result of DNA replication?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

What does DNA condense into during cell division?

Back

Chromosomes.

Front

What is the process called in which DNA makes an exact copy of itself?

Back

Replication.

Front

Which image represents DNA replication?

Back

Image (b).

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the three main components of a nucleotide?

Back

A phosphate group, a sugar, and a nitrogenous base.

Front

What is the role of helicase in DNA replication?

Back

To unwind the DNA double helix.

Front

What is the function of DNA polymerase?

Back

To synthesize new DNA strands by adding nucleotides.

Front

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

Back

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