10 Questions
What is the main enzyme involved in the replication process in living cells like E. coli?
DNA-dependent DNA polymerase
Why is it important for DNA polymerases to catalyze the reaction with a high degree of accuracy?
To avoid mutations
What would happen if there is a mistake during DNA replication?
Mutations may occur
What serves as the template for DNA polymerase during the replication process?
DNA molecules from a previous generation
What enzyme is responsible for catalyzing the polymerization of deoxynucleotides in E. coli?
DNA-dependent DNA polymerase
What provides energy for polymerization reactions in DNA replication?
Terminal phosphates in deoxynucleoside triphosphates
Why can't the two strands of DNA be separated over their entire length during replication?
Due to the high energy requirement
What is the term used to describe the small opening in the DNA helix where replication occurs?
Replication fork
Why is DNA replication continuous on one strand and discontinuous on the other?
As a result of the directionality of DNA polymerases
Which enzyme is responsible for joining the discontinuously synthesized fragments in DNA replication?
DNA ligase
