Step by step
Solved in 2 steps
- True or false? DNA repair mechanisms all depend on the existence of two copies of the genetic information, one in each of the homologous chromosomes. DNA primase makes DNA primers for the synthesis of Okazaki fragments in the DNA lagging strand. The repair of double-stranded breaks by nonhomologous end joining is accurate. RNA polymerase III transcribes all protein-coding genes."DNA repair mechanism all depend on the existence of two copies of the genetic information, one in each of the two homologous chromosomes" is true or false.Best DNA repair system to fix - Depurination - Replication Slippage - Deanimation of Cytosine - Double stranded dna break outside of S-phase
- All of these DNA-repair mechanisms use an undamaged complementary DNA strand as a template for replacing the excised nucleotides EXCEPT for____ base-excision repair. homologous recombination. mismatch repair. nonhomologous end joining. nucleotide-excision repairWhich of the following DNA repair mechanisms involves the 3’ to 5’ exonuclease function of DNA polymerase? postreplication repair mismatch repair SOS response DNA proofreading base excision repairWhich of the following DNA repair systems requires an involvement of the RecA protein? Mark all the correct answers Mismatch repair SOS response Photoreactivation repair DNA proofreading Postreplication repair
- Explain why base excision repair, nucleotide excision repair, and mismatch repair—which all require nucleases to excise damaged DNA—require DNA ligase.Which DNA repair mechanisms makes use of recombination between a damaged strand of a DNA molecule and an undamaged strand? Group of answer choices postreplication repair nucleotide excision repair antioxidant repair mismatch repair all of these are DNA repair mechanismsTRUE OR FALSE. Non-homologous end-joining as a DNA repair mechanism does not result in loss of nucleotides as a result of a double-strand break.
- What is divided into four phases: G1(the period between mitosis and the initiation of nuclear DNA replication), S (the period of nuclear DNA replica-tion), G2 (the period between the completion of nuclear DNA replication and mitosis), and M (mitosis).What a mutation is and how a cell detects and corrects most mutations that arise during DNA replication; the variedChromosomal ____________include those that removeor add base pairs (deletions and duplications), and thosethat relocate DNA regions (inversions and translocations).
