DNA Replication

Front

What are Okazaki Fragments?

Back

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

Front

What does semi-conservative DNA replication mean?

Back

It means that each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase adds nucleotides to the growing DNA strand complementary to the template strand.

Front

What is the function of Topoisomerase during DNA replication?

Back

Topoisomerase relieves the strain and prevents supercoiling as Helicase unwinds the DNA.

Front

What is the function of Helicase in DNA replication?

Back

Helicase unzips the DNA by breaking the hydrogen bonds between nitrogenous bases.

Front

What is the direction of DNA synthesis?

Back

DNA is synthesized in the 5' to 3' direction.

Front

What are the main steps of DNA replication?

Back

1. Initiation, 2. Unwinding, 3. Elongation, 4. Termination.

Front

What is the significance of the leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments (Okazaki fragments) due to the antiparallel nature of DNA.

Front

What is the role of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA Polymerase to begin synthesis.

Front

What are the base pairing rules in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).
