DNA Replication Model
Product Code : JC-BE-6093
The DNA Replication Model from Jaincolab is a three-dimensional teaching model that illustrates the semiconservative replication of DNA, including the roles of the key enzymes involved.
It is used in genetics, molecular biology, biotechnology, and medical courses to explain how a DNA molecule is accurately copied before cell division.
What the Concept States
| Parameter | Details |
|---|---|
| Semiconservative Replication | Each new DNA molecule retains one original (parent) strand and one newly synthesized strand |
| Helicase | Enzyme that unwinds the DNA double helix at the replication fork |
| Primase | Enzyme that synthesizes a short RNA primer to initiate DNA synthesis |
| DNA Polymerase | Enzyme that synthesizes new DNA strands by adding nucleotides in the 5' to 3' direction |
| Leading and Lagging Strand | The leading strand is synthesized continuously, while the lagging strand is synthesized discontinuously as Okazaki fragments |
| DNA Ligase | Enzyme that joins Okazaki fragments to form a continuous lagging strand |
Key Features

Frequently Asked Questions
Q1. What does the DNA Replication Model demonstrate?
A. It demonstrates the semiconservative replication of DNA and the roles of the enzymes involved, including helicase, primase, DNA polymerase, and DNA ligase.
Q2. What does semiconservative replication mean?
A. It means that each newly formed DNA molecule contains one original parent strand and one newly synthesized strand.
Q3. What is the difference between the leading and lagging strand?
A. The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized discontinuously as short Okazaki fragments.
Q4. What is the role of DNA ligase?
A. DNA ligase joins the Okazaki fragments on the lagging strand to form a continuous DNA strand.
Q5. Who uses this model?
A. Genetics, molecular biology, biotechnology, and medical students and faculty use it to study DNA replication.
