Answer:
1.helicase begins to break the hydrogen bonds between nitrogen bases.
free floating nucleotides pair up with exposed nitrogen bases.
dna polymerase attach the free-floating nucleotides to the exposed nitrogen bases.
two new molecules of dna are created.
cell starts into the mitosis phase of a cell cycle.
2. The hydrogen bonds holding the base pairs together in a DNA molecule are relatively weak compared to other chemical bonds. ... The new nucleotides join together to form the sugar-phosphate backbone of a new strand of DNA. The result is two DNA molecules identical to the original.
3.Each original DNA strand attracts new nucleotides that plug into their complementary bases on the original strand. The new nucleotides join together to form the sugar-phosphate backbone of a new strand of DNA. The result is two DNA molecules identical to the original.
4.Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus.
