DNA Replication

Front

In what phase of the cell cycle does DNA replication take place?

Back

S phase

Front

What are the nitrogenous bases found in DNA?

Back

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

Front

What is the role of hydrogen bonds in DNA?

Back

Hydrogen bonds hold the two strands of the DNA double helix together.

Front

What is the structure of DNA?

Back

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

Front

What is a nucleotide?

Back

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

Front

What is the function of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is crucial for DNA replication, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is semi-conservative replication?

Back

Semi-conservative replication means that each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What are the base pairing rules in DNA?

Back

A pairs with T, and C pairs with G.
