DNA Replication

Front

What bond holds the two DNA strands together?

Back

Hydrogen bond

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

Where is DNA usually found in a cell?

Back

DNA is usually found in the nucleus of a cell.

Front

What forms the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate form the sides (backbone) of the DNA ladder.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What enzyme unwinds the DNA double helix during replication?

Back

Helicase is the enzyme that unwinds the DNA double helix.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures that the DNA strands are accurate copies of each other, with adenine pairing with thymine and cytosine pairing with guanine.

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.
