Note, possible conception could be anytime between about one and five days after sex, depending on when you had sex in your fertile window in relation to ovulation. 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.
This method is called  Semi-conservative  which replicates the DNA so it begins with unzipping, unwinding the DNA by breaking down the hydrogen bonds between the nitrogenou â¦ s bases with the help of  helicase enzyme  that helps separating the strands.he original strand of DNA is unzipped by an enzyme that breaks the  hydrogen bonds between the bases. This process continues until the  entire strand of DNA has been unzipp â¦ ed and copied.
