Which of the following is correct about the function of DNA Ligase? DNA ligase is used on the leading strand and it joins any disconnected strand together O DNA ligase is used on the lagging strand which helps in joining fragments of the strand together O DNA ligase is used on the lagging strand and it aids in correcting mistakes on this specific strand O DNA ligase is used to maintain the replication fork structure
Which of the following DNA repair mechanisms relies on homologous DNA recombination for the repair process? DNA proofreading O SOS response postreplication repair base excision repair mismatch repair
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
In DNA Replication, what is the function of Primase: works to connect discontinuous parts of DNA such as the nicks created by gyrase and the okazaki fragments O Synthesizes RNA on a DNA template to provide an available 3'-OH group to continue with DNA synthesis O binds at the origin and begins to unwind the helix O bind near the origin to maintain the complementary sequences of DNA from reforming the helical structure
single strand binding proteins are important for this activity prevent replication of the ends of the chromosomes prevent denaturation of the dsDNA template prevent the double helix from becoming a triple helix prevent single stranded DNA strands from rewinding and snapping back as double stranded
Which of the following statements about DNA replication is correct? Group of answer choices the leading strand is replicated continuously, while the lagging strand is replicated discontinuously on the leading strand, the new nucleotides are added only to the 5' end of the nucleotide chain on the lagging strand, the new nucleotides are added only to the 5' end of the nucleotide chain DNA polymerase works from 3'--> 5' only
Select the characteristics/descriptions of DNA polymerase. Select ALL that apply requires a primer adds nucleotides to 3' end of DNA strand adds nucleotides to 5' end of DNA strand does not require primer has 3'-to-5' exonuclease activity that allows "proofreading" of DNA strand being made
During DNA replication, DNA polymerase adds nucleotides to the: 3' end of the newly synthesized strand as it moves toward the 3' end of the template strand 3' end of the newly synthesized strand as it moves toward the 5'end of the template strand 5' end of the newly synthesized strand as it moves toward the 5' end of the template strand 5' end of the newly synthesized strand as it moves toward the 3' end of the template strand none of the above 0 0 0 0 0

Match the proteins with their function in DNA replication. unwinds DNA at replication fork forms covalent phosphodiester bonds to join DNA fragments remove primer and replace the RNA with DNA, also has 3'-> 5'exonuclease activity for proofreading synthesizes DNA by adding to the 3' end of the growing strand of DNA adds RNA primer uses an RNA template to facilitate extension of the telomeres in eukaryotes helicase DNA ligase DNA polymerase II introduces a double-stranded break ahead of the replication fork and swivels the cleaved ends around the central axis to relieve the stress of helix unwinding DNA polymerase III DNA primase telomerase DNA Gyrase (topoisomerase)
The tuble below shows part of the process of DNA replication Origin al ONA Strand Complementary DNA Strand A-C-C-G-T-A-C T-G-G-A A-T-G What is the most likely effect this could have on genetic information going forward? O There willl be no change in the genetic information that gets transmitted because the complementary strand will never be used as a template O There will not be a change in the genetic information that gets transmitted because the cells having the new section of DNA will cored any mutations O There will be a change in the genetic information that gets transmitted due to the complementary strand being used as a template in fulure DNA replication. OThere will be a change in the genetic information that gets transmitted because the sections of DNA with mistakes will be passed on to make future generalions songer
