Which of the following statements is FALSE about double-strand breaks (DSBs)?
A. Non-homologous end-joining between the ends of two DSBs can create inversions or translocations.
B. Spo11-mediated DSBs initiate meiotic recombination.
C. Unrepaired DSBs are lethal to a cell.
D. Unrepaired DSBs trigger a checkpoint that arrests cells in G2.
E. Cas9 can be targeted to make a DSB at a specific genomic sequence by annealing a small piece of single-stranded DNA that is complementary to the cut site.
Homework Answers
Ans-Cas9 can be targeted to make a DSB at a specific genomic sequence by annealing a small piece of single-stranded guide RNA (g RNA) that is complementary to the cut site.
Non-homologous end-joining pathway repairs DSB and creates inversion or translocation.
Spo11 initiates mitotic recombination by the formation of programmed DSBs.Unrepaired DSB causes arrest cells in G2.
so option E Cas9 can be targeted to make a DSB at a specific genomic sequence by annealing a small piece of single-stranded DNA that is complementary to the cut site is a false statement about DSB

Haploid yeast cells that preferentially repair double-strand breaks by homologous recombination (rather than by non-homologous end joining) are especially sensitive to agents that cause double-strand breaks in DNA. If the breaks occur in the G1 phase of the cell cycle, most cells will die; however, if the breaks occur in the G2 phase, a much higher fraction of cells survive. Why do you suppose this is?

The process of homologous recombination is a means to repair double-strand breaks, the most lethal form of DNA damage. Arrange the sequence of events in the proper order: 1. ATR recognizes single-stranded ends, binds to them, and initiates signaling. 2. RAD51 complexes with ssDNA and searches for homologous sequences. 3. MRN nuclease trims the 5' ends, leaving ss-3' ends that are coated with replication protein A. 4. ATM activates a nuclease in MRN and signals downstream effectors. 5. RAD51-ssDNA complex...

strand, resulting in double-stranded breaks (DSBs) that trigger cellular repai mechanisms. In eukaryotes, the DSBs are more commonly repaired by the mechanism ot error prone non ho mologous end joining (NHEJ), therefore generating sequence changes, for instance insertions and deletians (indels), around the DSBs. Owing to the simplicity of manipulation and versati ity, the CRISPR/Cas9 system has been...
