DNA Structure and Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

Which nucleotide pairs with adenine in DNA?

Back

Thymine.

Front

Where is DNA usually found in a cell?

Back

In the nucleus.

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, nitrogen base.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, thymine, cytosine, guanine.

Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of complementary base pairing?

Back

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

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix, separating the two strands of DNA.
