What is the function of DNA helicase in DNA replication? to create an RNA primer to initiate DNA replication to insert new bases during elongation, using the parent strand as a template O to anneal (splice) smaller fragments of DNA to create one continuous strand to create replication bubbles by unravelling the parental strands of DNA O all of the above

During semi-conservative DNA replication, which step must occur first? The hydrogen bonds found between the nitrogenous bases must be broken. RNA must be transcribed. New plasmids must be synthesized. The phosphodiester bonds between the nucleotides must be broken.

If a mutation occurred that prevented single stranded binding proteins from binding, the result would be: O Replication would not be initiated O DNA would be synthesized on the leading strand, but not the lagging strand Replicating would be initiated, DNA would unwind, RNA primers would be laid down, but DNA polymerase would not bind O The newly synthesized RNA would not be able to leave the DNA template Replication would be initiated, but RNA primers would not anneal to the DNA

Which of the following is not necessary for replication to proceed? O MRNA O RNA primer O DNA polymerase O primase O DNA ligase

As the strands are synthesized in replication, which of the following is true?   the leading strand is synthesized continuously from the 5' to 3' direction while the other strand is synthesized discontinuously in the 3' to 5' direction   both strands are synthesized  in the 5' to 3' direction   the strand that shows the Okazaki fragments is synthesized in the 3'-5' direction.   both strands are synthesized continuously

Which statement is true about dna replication

Semi-discontinuous replication means that:     DNA synthesis only occurs in the same direction as the replication fork.     the double helix unwinds and each strand serves as a template for a new DNA molecule.     there are Okazaki fragments associated with the leading strand.     DNA synthesis occurs in both a 5’ to 3’ and a 3’ to 5’ direction.     there is both a leading and a lagging strand associated with each replication fork.

Given the replication events listed below which even takes place first Single Strand binding proteins bind Primase adds an RNA primer Helicase unwinds the DNA double helix  DNA polymerase begins adding DNA nucleotides

Define DNA replication/synthesis and semiconservative replication.  In addition, describe and/or define the role(s) of each of the following in the process of DNA replication/synthesis: DNA template strand, 5’ and 3’ ends, DNA helicase, DNA polymerase, single-strand binding proteins, topoisomerase, primase, Okazaki fragments, leading strand and lagging strand.
