replication of DNA

Front

What type of replication method is used by both prokaryotes and eukaryotes?

Back

Semiconservative replication is the method used by both prokaryotes and eukaryotes.

Front

What happens to the DNA primer after the base pairing stage of DNA replication ends and joining begins?

Back

RNA primers are removed and replaced with nucleotides.

Front

Which scientist(s) first suggested that semiconservative replication was the method of DNA replication?

Back

Watson and Crick first suggested that semiconservative replication was the method of DNA replication.

Front

On which strand(s) does the enzyme DNA ligase act during replication?

Back

DNA ligase acts on the lagging strand during replication.

Front

With what does the synthesis of a new strand of DNA begin?

Back

The synthesis of a new strand of DNA begins with an RNA primer.

Front

What is the role of DNA helicase in DNA replication?

Back

DNA helicase unwinds the double helix structure of DNA, separating the two strands.

Front

What is the function of DNA polymerase during DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between the leading strand and the lagging strand in DNA replication?

Back

The leading strand is synthesized continuously in the same direction as the replication fork, while the lagging strand is synthesized in short segments (Okazaki fragments) in the opposite direction.

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 significance of the semiconservative nature of DNA replication?

Back

The semiconservative nature of DNA replication ensures that each new DNA molecule contains one original strand and one newly synthesized strand, preserving genetic information.
