Replication

Question 1

DNA replication begins at the origin of replication. How does this process occur?

Answer 1

To start this process, the DNA helix hydrogen bonds are seperated to produce two single stranded templates (These templates will be parental templates.)

Question 2

What is DNA polymerase?

Answer 2

DNA polymerase is the enzyme that catalyzes the synthesis of new DNA

Question 3

Where do the new nucleotides get attached by DNA polymerase? (remember that nucleotides are a monomer for the nucleic acid polymer and DNA is a nucleic acid)

Answer 3

DNA polymerase will add the new nucleotides to the 3’-end of the growing DNA molecule

Question 4

During this process, DNA polymerase causes the formation of what bond between the 3’-OH and the 5’-phosphate?

Answer 4

phosphodiester bonds (covalent bond)

Question 5

Where does the energy come from during this synthesis of DNA replication?

Answer 5

the energy comes from the triphosphate group of the new nucleotides being built/added

Question 6

What is the role of the DNA helicase enzyme in this process of DNA replication?

Answer 6

DNA helicase has the role of unwinding the DNA double helix (the structure of DNA) and this results to single stranded templates
