Q. What is the role of enzymes in the DNA replication process?
1. Enzymes read the DNA code and build a new DNA molecule from scratch.
2. Enzymes link together to form a template for a new DNA molecule to be built.
3. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
4. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Answer: 4 (Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail).
Explanation: DNA replication is not a random process, so replication starts at a particular site in the chromosome using different enzymes.
DNA replication is a complex process that occurs in three steps including initiation, elongation, and termination. These steps require several enzymes and proteins. The studies found that more than 20 different enzymes and proteins play a central role in prokaryotic DNA replication. These proteins have been classified on the basis of their biochemical functions in different stages of DNA replication.
