DNA Structure and Replication

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that wind around each other.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

What base does adenine pair with in DNA?

Back

Adenine pairs with thymine (T) in DNA.

Front

What base does cytosine pair with in DNA?

Back

Cytosine pairs with guanine (G) in DNA.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of the sugar-phosphate backbone in DNA?

Back

The sugar-phosphate backbone provides structural support and stability to the DNA molecule.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself, involving unwinding the double helix and synthesizing new strands.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is the role of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds the DNA double helix, separating the two strands.
