DNA Replication

Front

What is the base pairing rule in DNA?

Back

In a double-stranded DNA molecule, Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Front

What enzyme is known as 'The Builder' in DNA replication?

Back

DNA Polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

Front

During which phase of the cell cycle does DNA replication occur?

Back

DNA replication occurs during the S phase (Synthesis phase) of the cell cycle.

Front

Where is DNA primarily located within a cell?

Back

DNA is primarily found in the nucleus of eukaryotic cells.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases in DNA are joined by hydrogen bonds.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of the DNA double helix during replication.

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication.

Front

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

Back

The S phase is significant because it is the stage where DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other, with a sugar-phosphate backbone and nitrogenous bases in the center.
