Which best describes an Okazaki fragment?
|
|
A piece of single strand DNA that gets replicated into double strand DNA
|
|
|
A small piece of RNA attached to the DNA strand to start replication.

|
|
Complementary pieces of DNA that match to the lagging strand

|
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: -Okazaki fragments are short, newly synthesized DNA fragments that are formed on the lagging template strand during DNA replication. They are complementary to the lagging template strand, together forming short double-stranded DNA sections.
