FLASHCARD QUESTION

Front

Who is known for using X-ray crystallography to determine the structure of DNA?

Back

Rosalind Franklin is known for her work with X-ray crystallography, which helped reveal the double helix structure of DNA.

3.

FLASHCARD QUESTION

Front

Which enzyme is NOT involved in DNA replication?

Back

RNA Polymerase is not involved in DNA replication; it is used in transcription.

4.

FLASHCARD QUESTION

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of DNA, creating a replication fork.

5.

FLASHCARD QUESTION

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.

6.

FLASHCARD QUESTION

Front

What are Okazaki fragments?

Back

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

7.

FLASHCARD QUESTION

Front

What is the function of DNA ligase?

Back

DNA ligase is the enzyme that joins Okazaki fragments together, sealing the gaps in the sugar-phosphate backbone.
