Biology DNA Replication

Front

What is the structure of each daughter DNA molecule after replication?

Back

Each daughter DNA molecule is composed of one original strand and one new strand.

Front

What enzyme synthesizes the leading strand during DNA replication?

Back

DNA polymerase synthesizes the leading strand.

Front

What enzyme synthesizes the lagging strand during DNA replication?

Back

RNA polymerase does not synthesize the lagging strand; DNA polymerase synthesizes both strands.

Front

What is the role of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand.

Front

What is the function of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.

Front

At which end of a growing DNA strand are new nucleotides added?

Back

New nucleotides are added to the 3' end of an already placed nucleotide.

Front

What is the significance of the 5' to 3' direction in DNA replication?

Back

DNA strands are synthesized in the 5' to 3' direction, which is crucial for the replication process.

Front

What are Okazaki fragments?

Back

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

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands.

Front

What is the difference between leading and lagging strands?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments.
