|
|
Okazaki Fragments
|
|
|
Continuous strand
|
|
|
All of them
|
Explanation:
Detailed explanation-1: -Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.
Detailed explanation-2: -Short segments of replicated DNA are called Okazaki fragments. DNA built up of Okazaki fragments is known as the lagging strand. These fragments are joined by the enzyme DNA ligase.
Detailed explanation-3: -On the upper lagging strand, synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template. This produces a series of disconnected Okazaki fragments.
