How dna strands are held together
WebJames Watson and Francis Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Purines and pyramidines form base-pairs through hydrogen bonding which keep the two DNA stands stable. However, the nucleotides form base pairs with a specific partner. WebA DNA strand has a phosphate at the 5' end and a hydroxyl group at the 3' end. The two strands in a DNA molecule have the same 5' to 3' orientation. Complementary DNA …
