The process of breaking the hydrogen bonds between the nucleotide base pairs in double-stranded DNA requires energy. To break the bonds, helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells.he process of breaking the hydrogen bonds between the nucleotide base pairs in double-stranded DNA requires energy.

Estrogen and progesterone are the female hormones produced by the ovaries. These hormones cause monthly menstrual cycles to occur. These hormones also help eggs to develop in follicles, which are fluid-filled pockets, before an egg is released each month to travel down the fallopian tube.
