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.
An enzyme called DNA gyrase makes a nick in the double helix and each side separates; An enzyme called helicase unwinds the double-stranded DNA; Several small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separated An enzyme complex called DNA polymerase walks down the DNA strands and adds new nucleotides to each strand.
