Question

iz Instructions Question 3 1 pts PCR is used for cloning DNA and after about 30 cycles, the number of copies of DNA will have increased about a billion times. Why is the DNA polymerase from the bacteria Thermus aquaticus used in PCR? Due to the walls of the he plant cell, which are thick: therefore it is used to degrade the walls for PCR to begin. O It is present and needed because the enzyme is resistant to very high temperatures since the bacteria live in hot springs. O It allows scientists to be able to determine the variable number of tandem repeats of minisatellites or microsatellites to determine an individual's DNA fingerprint. It is used to flank the gene to be copied. Because it uses primers specific to sequences in a disease causing gene or O organism to diagnosis diseases, etc. 5

Explanation / Answer

It is present and needed because the enzyme is resistsnt to very high temperatures since the bacteria live in hot springs.
