This is because sperm can live in the female reproductive tract for up to five days and the egg can survive for about 12-24 hours after ovulation.
What enzyme unwinds DNA? A: The powerful enzyme DNA helicase unwinds the double strands of DNA by breaking the bonds between each of the complementary bases. These bases are held together by strong hydrogen bonds, but in breaking these, DNA helicase creates two single-stranded DNA molecules. Continue Reading.
