Difference Between Conservative and Semiconservative Replication
The table given below summarises the key differences between Conservative and Semi-conservative Replication:
Features |
Conservative Replication |
Semiconservative Replication |
---|---|---|
Definition |
In this type of replication, one entirely old and entirely new DNA is produced. |
In this type of replication, both newly formed DNAs consist of one old and one new strand. |
Type of Replication Model |
It is a theoretical model of replication. |
It is an actual proven model of replication. |
Significance |
It is not found to be biologically significant. |
It is biologically significant. |
Unwinding of Parent DNA |
No unwinding of parent DNA occurs. |
Parent DNA unwinds and opens for replication. |
Role of Template Strand |
Not clear |
Each strand of the parent DNA molecule works as a template strand for the formation of a new strand. |
Synthesis of New DNA Strand |
New DNA strands are formed away from parental strands. |
New DNA strands are formed alongside the parental strands. |
DNA Helices |
Out of the two DNA helices, one has entirely new DNA and the other has entirely old DNA. |
Both DNA helices are made up of one new strand and one old strand. |
Mechanism of Proofreading. |
Lacks an efficient proofreading mechanism. |
It has an efficient proofreading mechanism and is done by DNA polymerase. |
Difference between Conservative and Semiconservative Replication
Conservative Replication and Semiconservative Replication are the two proposed models of replication. In the DNA replication process of conservative replication, the original DNA remains intact and serves as a template for the synthesis of two new DNA molecules.
In semiconservative replication, each original DNA strand serves as a template for the synthesis of a new strand, resulting in two DNA molecules, each with one original strand and one new strand. Semiconservative replication is the most accepted model of DNA replication. In this article, we will read about semiconservative and conservative replication and the differences between them.
