DNA replication and enzymes

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is replicated continuously in the 5' to 3' direction.

Front

Why is DNA replication necessary?

Back

DNA replication is necessary to create another copy of DNA for new cells during cell division.

Front

What is the order of DNA replication?

Back

The order of DNA replication is 3, 4, 1, 2, which corresponds to specific steps in the replication process.

Front

What is the function of DNA ligase?

Back

DNA ligase seals the Okazaki fragments and other DNA fragments together during replication.

Front

What does semiconservative replication mean?

Back

Semiconservative replication 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 role of DNA polymerase in replication?

Back

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

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is the DNA strand that is replicated discontinuously in short segments (Okazaki fragments) in the 5' to 3' direction.

Front

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

Back

The 5' and 3' ends refer to the directionality of the DNA strand, which is crucial for the synthesis and replication process.

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds the DNA double helix, separating the two strands to allow replication.
