DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA, ensuring that each new cell receives a complete set of genetic information.

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication.

Front

What is the function of DNA ligase?

Back

DNA ligase is the enzyme that joins Okazaki fragments together to form a continuous DNA strand.

Front

What does helicase do during DNA replication?

Back

Helicase unwinds and separates the double-stranded DNA into two single strands.

Front

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

Back

These refer to the directionality of the DNA strands, which is crucial for the synthesis of new DNA.

Front

What is the shape of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder.

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.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is synthesized discontinuously in short segments, opposite to the direction of the replication fork.

Front

What is the role of RNA primer in DNA replication?

Back

The RNA primer provides a starting point for DNA polymerase to begin DNA synthesis.
