WebOct 12, 2024 · Two strands of DNA bind together to form the double helix because of the way each strand is both attracted and repelled by the other strand. The two strands bind through the bonding of the bases of each nucleotide i.e. the bases from one strand bond to the bases of the second strand of DNA.

WebThat’s because our DNA strand is so long that DNA replication actually starts in several origins along the chromosomes simultaneously.
