DNA Replication

Front

What is the replication fork in DNA replication?

Back

The replication fork is the area where the DNA double helix is unwound to allow for replication to occur, creating two single strands that serve as templates for new DNA strands.

Front

What is the complementary nucleotide for Cytosine in DNA?

Back

Guanine.

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 are Okazaki fragments?

Back

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

Front

What does anti-parallel mean in the context of DNA?

Back

Anti-parallel refers to the orientation of the two strands of DNA, where one strand runs in the 5' to 3' direction and the other runs in the 3' to 5' direction.

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 is the difference between the leading and lagging strands?

Back

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

Front

What is the function of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds the DNA double helix at the replication fork.

Front

What are the base pairing rules in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

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 strands, which is crucial for the synthesis and replication process.
