Restriction endonuclease and ligase are two types of enzymes used in the process of genetic engineering, i.e., the manipulation of genes. The restriction endonuclease differs from ligase in that it breaks the DNA at ends, while ligase causes the breaks in DNA from interior joins the fragments of DNA, while ligase breaks the DNA into fragments breaks the DNA at specific points, while the ligase joins the fragments of DNA breaks the DNA apart at each nucleotide, while ligase use the pieces to translate

If a restriction enzyme cuts at this DNA sequence: TACGGAT, in general what is this sequence called?

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…

The function of the 3'-> 5' exonuclease activity is found in which of the following: DNA Polymerase III DNA Polymerase I DNA Polymerase II All of the above
