Which of the following is NOT a characteristic of Okazaki fragments?
A
They are synthesized continuously on the leading strand.
B
They are formed during DNA replication on the lagging strand.
C
They are later joined by DNA ligase.
D
They are short sequences of DNA nucleotides.
Verified step by step guidance1
Understand the context: Okazaki fragments are short sequences of DNA nucleotides synthesized during DNA replication.
Identify the role of Okazaki fragments: They are formed on the lagging strand of DNA, not the leading strand.
Recognize the synthesis process: Okazaki fragments are synthesized discontinuously, as opposed to the continuous synthesis on the leading strand.
Learn about the joining process: After synthesis, Okazaki fragments are joined together by the enzyme DNA ligase to form a continuous DNA strand.
Evaluate the options: The statement that Okazaki fragments are synthesized continuously on the leading strand is incorrect, as they are synthesized discontinuously on the lagging strand.
