Questions & Step-by-Step Solutions
What are Okazaki fragments?
Step 1: Understand that DNA is made up of two strands that are complementary to each other.
Step 2: During DNA replication, these strands need to be copied so that each new DNA molecule has one original strand and one new strand.
Step 3: One of the strands is called the leading strand, which is copied continuously in the same direction as the replication fork opens.
Step 4: The other strand is called the lagging strand, which is copied in short segments because it runs in the opposite direction of the replication fork.
Step 5: These short segments on the lagging strand are called Okazaki fragments.
Step 6: Okazaki fragments are later joined together to form a continuous strand of DNA.
Okazaki Fragments – Short segments of DNA synthesized on the lagging strand during DNA replication.
Lagging Strand – The strand of DNA that is synthesized discontinuously in short segments.
DNA Replication – The process by which a cell duplicates its DNA before cell division.
