5. dna polymerase is an enzyme that put dna molecules together. a
chain reaction is a process in which one event leads to the next event and the
effect is stronger over time. how does the combination of these two terms
describe what happens during pcr?

but there is no

i guess you forgot putting it.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
