DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, resulting in two identical DNA molecules.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

What base pairs with adenine in DNA?

Back

Thymine (T) pairs with adenine (A) in DNA.

Front

What base pairs with cytosine in DNA?

Back

Guanine (G) pairs with cytosine (C) in DNA.

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of DNA, allowing replication to occur.

Front

What is the function of DNA polymerase?

Back

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

Front

What is a template strand in DNA replication?

Back

A template strand is the original strand of DNA that serves as a guide for the synthesis of a new complementary strand.

Front

What is the significance of the semi-conservative model of DNA replication?

Back

The semi-conservative model means that each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What are Okazaki fragments?

Back

Okazaki fragments are short segments of DNA synthesized on the lagging strand during DNA replication.

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the same direction as the replication fork.
