DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an identical copy of its DNA before cell division.

Front

What is the role of DNA helicase in DNA replication?

Back

DNA helicase unwinds the original DNA strand, separating the two strands to allow replication.

Front

What is the function of RNA primase during DNA replication?

Back

RNA primase lays down an RNA primer that provides a starting point for DNA polymerase to begin synthesis.

Front

What does DNA polymerase do?

Back

DNA polymerase builds new strands of DNA by adding complementary nucleotide bases to the growing strand.

Front

What is the significance of the leading strand in DNA replication?

Back

The leading strand is synthesized continuously in the direction of the replication fork, allowing for faster replication.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is synthesized in short segments (Okazaki fragments) away from the replication fork, making it slower to replicate.

Front

What does 'antiparallel' mean in the context of DNA structure?

Back

Antiparallel refers to the opposite orientation of the two strands of DNA; one strand runs 5' to 3' and the other runs 3' to 5'.

Front

What is the complementary strand for 3' A A A T T T C 5'?

Back

5' T T T A A A G 3'.

Front

What enzyme is responsible for joining Okazaki fragments on the lagging strand?

Back

DNA ligase knits together the fragments on the lagging strand.

Front

What is the role of DNA replication in cell division?

Back

DNA replication ensures that each daughter cell receives an identical set of DNA during cell division.
