Suggest a reason for the rather large energy excess available in the insertion of a deoxyribonucleotide into a growing dna molecule. (about three times as much energy as is necessary is available in the reaction dntp dnan → dnan 1 pyrophosphate.)
a. the excess energy is used to produce atp to be used as a energy source in the rest of the cell.
b. the very favorable forward reaction means that the reverse reaction is very unfavorable.
c. the extra energy is used to drive the reassembly of the two separated dna template strands.
d. the energy is used by dna gyrase to supercoil dna

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.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
