Okazaki fragments are joined topether by: a RNA polymerase b DNA ligase DNA Polymerase d RNA ligase A"if the statenew In DNA replication, the lagging strand is as a series ofokazaki fagments Bacterial chromosome is circular and replicated from origin of repli bidirectionally replicated while are linear and are replicated from multiple origins af replication bidinectionally In ene strand efa DNA molecule, adjacent nucleotides are joined by an strand reg DNA by 5.An RNA primer is synthesized by BNAArimer 36. Also know some differences between DNA and RNA. Example, DNA is made up of G ATC. Which of these nucleotides is not found in RNA? What is found instead? 37. Refer to Hershey and Chase experiment: True or False, phosphate (P) is found naturally in DNA but not in proteins while Sulphur (S) is found in proteins but not in DNA- 38. Know the 3 parts of a nucleotide.Explanation / Answer
Answer:
22). b. one parental strand and one new strand
Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
23). B. Meselson and Stahl
Matthew Meselson and Franklin Stahl were the first to demonstrate that DNA replication is semiconservative.
24). E. conservative
Conservative replication would leave the two original template DNA strands together in a double helix and would produce a copy composed of two new strands containing all of the new DNA base pairs.
25). B. DNA helicase
DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
26). B. Single-stranded binding proteins
Single-stranded DNA-binding proteins play a role in separating DNA strand during replication and prevent ssDNA from re-form a double helix.
27). A. Topoisomerases
Topoisomerase produces breaks in the DNA molecules and then rejoin the strands, preventing supercoiling and knot formation during replication
