Question

In the laboratory,which of the following two factors are most useful in manipulating DNA?
A)magnesium ions and sugar concentrations
B)UV light and calcium ions
C)formaldehyde and iron ions
D)temperature and pH

Accepted Answer

Temperature and pH are the most useful factors in manipulating DNA in the laboratory. Different temperatures can affect DNA polymerase activity, while changes in pH can affect the stability and interaction of DNA with other molecules. Other factors listed may also have some effect on DNA, but they are not the most commonly used or important in DNA manipulation.
