Top Trending DNA Replication Quizzes

Stitches in Time: Okazaki Fragments Explained

DNA polymerase can only build in one direction, but the two template strands run antiparallel to each other, which creates an elegant problem with an equally elegant solution. Okazaki fragments explained reveals how the...

Questions: 20 | Attempts: 10 | Last updated: Mar 3, 2026

Sample Question 1
Why must the lagging strand be synthesized in a discontinuous manner?

DNA polymerase can only add nucleotides in the 5' to 3' direction

The lagging strand is much longer than the leading strand

There are not enough nucleotides for a continuous strand

The lagging strand is made of RNA

Helicase moves backward on the lagging strand

Sample Question 2
The short segments of DNA synthesized on the lagging strand are known as okazaki fragments.

True

False

The Master Builders: DNA Polymerase Function

DNA replication is not a solo act. It requires a coordinated team of enzymes working in a precise sequence, and two of the most critical players are DNA polymerase and primase. Dna polymerase function centers on synthesizing...

Questions: 20 | Attempts: 10 | Last updated: Mar 3, 2026

Sample Question 1
What is the fundamental dna polymerase function during DNA replication?

Synthesizing new DNA strands by adding nucleotides

Unzipping the double helix

Building RNA primers

Joining Okazaki fragments

Repairing the cell membrane

Sample Question 2
Primase is necessary because DNA polymerase cannot initiate the synthesis of a polynucleotide on its own.

True

False
