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

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
