Primase has the important role of removing the RNA primers and filling the gaps with new DNA nucleotides. Prokaryotic organisms (like bacteria) have multiple origins of replication on many linear chromosomes. The new DNA strand is synthesized ina discontinuous manner away from the. replication fork on the lagging strand. RNA primers are not required for synthesis of the new DNA strand on the leading strand.

Which statement is true about
Step by step
Solved in 3 steps
- DNA polymerase occasionally incorporates the wrong nucleotide during DNA replication. If left unrepaired, the base-pair mismatch that results will lead to mutation in the next replication. As part of a template strand, the incorporated wrong base will direct the incorporation of a base complementary to itself, so the bases on both strands of the DNA at that position will now be different from what they were before the mismatch event. The MER-minus strain of yeast does not have a functional mismatch excision repair system, but it has normal base excision repair and nucleotide excision repair systems. Which of the following statements is correct about differences in the mutation spectrum between MER-minus and wildtype yeast? More than one answer is correct. Options: More point mutations will arise in MER-minus yeast. Fewer point mutations will arise in MER-minus yeast as compared with wildtype. Of the total point mutations that…During template-directed synthesis of a new DNA strand it can happen, if there are simple repeated sequences, that either the template strand or the strand being synthesized "slips" a short distance, and this can change the number of repeating sequence units in that stretch of repeated sequence. Which of the following processes involve such slippage? More than one answer is correct. Options: The increase in genomic copy number of a DNA transposon by transposition from a location behind a replication fork to a location ahead of the fork. Introduction of indels during DNA replication. The initial unwinding of the DNA duplex during replication by helicase. Increasing lengths of CAG trinucleotide repeats in the huntingtin gene giving rise to Huntington disease. Synthesis of primer by primase during DNA replication.The purpose of DNA gyrase in replication is: to relieve positive supercoiling induced by unwinding the DNA during replication. to induce tighter coiling in supercoils. to remove the RNA primers from the lagging strand at each Okazaki fragment to start unwinding and separate the DNA to initiate replication to provide energy to remove a diphosphate fragment from each nucleoside triphosphate.
- During eukaryotic DNA replication, _________ synthesizes short RNA primers. The primers provide a 3'-OH group to which DNA nucleotides are be added by DNA polymerase. DNA gyrase (topoisomerase) DNA helicase DNA ligase primase. During DNA repair in prokaryotes and eukaryotes, which of the following enzymes replaces the damaged nucleotides, that were excised from the DNA strand, by inserting the correct nucleotides? topoisomerase DNA polymerase DNA helicase an exonuclease DNA ligaseSingle-strand binding proteins keep the two parental strands of DNA separated from each other until DNA polymerase has an opportunity to replicate the strands. Suggest how single-strand binding proteins keep the strands separated and yet do not impede the ability of DNA polymerase to replicate the strands.
- Multiple origins of replication on the DNA molecule of eukaryotic cells serve to Question 41 options: remove any errors in replication that may have occurred create multiple copies of the DNA molecule at the same time shorten the duration of time necessary for DNA replication reduce the number of "replication bubbles" that occur in the DNA double helix during replication assure the correct orientation of the two strands in the newly growing double helixDuring DNA replication, the function of RNA primers is to Group of answer choices serve as a binding site for DNA ligase separate the two strands of the double helix to open replication "bubbles" serve as starting points for DNA strand elongation by DNA polymerase in the 3' - 5' direction prevent new-separated strands of DNA from rejoining serve as starting points for DNA strand elongation in the 5' - 3' direction by DNA polymeraseWhich of the following reactions is required for proofreading during DNA replication by DNA polymerase III?a) 5’ to 3’ exonuclease activityb) 3’ to 5’ exonuclease activityc) 3’ to 5’ endonuclease activityd) 5’ to 3’ endonuclease activity
- Shown below is a long template strand of DNA where lagging strand DNA synthesis is occurring. The short horizontal lines represent two Okazaki fragments that have already been made. In the context of the replication fork, select the letter(d–g) that indicates where primase will synthesize the next RNA primer. Explain why did you choose that location?An investigator obtains a bacterial temperature-sensitive mutation that affects a step in the process of DNA replication at 42°C but not at 30°C. She grows the cells at 30°C and, upon shifting the temperature to 42°C, she discovers that Okazaki fragments accumulate in unusually large quantities. What is the likely target affected by the temperature-sensitive mutation? primase DNA polymerase III DNA helicase DNA Ligase DNA gyraseDuring DNA replication in E. coli, which enzyme forms the phosphodiester bond between an RNA primer and the first incoming deoxyribonucleotide for an Okazaki fragment on the lagging strand? topoisomerase DNA polymerase III DNA helicase DNA polymerase II DNA ligase
