DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

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

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 a template strand in DNA replication?

Back

A template strand is the original strand of DNA that guides the synthesis of a new complementary strand.

Front

What is the significance of the 5' and 3' ends of DNA strands?

Back

The 5' and 3' ends indicate the directionality of the DNA strands, which is crucial for the replication process.

Front

What is semi-conservative replication?

Back

Semi-conservative replication is the method of DNA replication where 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 function of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the double-stranded DNA during replication.

Front

What is the role of ligase in DNA replication?

Back

Ligase is an enzyme that joins Okazaki fragments together to form a continuous DNA strand.
