DNA gyrase decreases the number of positive supercools. What is the result of this process?

How many unique primers are required to amplify a single DNA target region?   a) 1 b) 2 c) 4 d) number varies according to length of target region

How many times would telomerase have to bind to a different site in the telomere to make a segment of DNA that is 36 nucleotides in length?

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…
