Detailed explanation-1: -DNA is composed of two strands of nucleotides held together by hydrogen bonding. The strands each run from 5’ to 3’ and run in antiparallel, or opposite, directions from one another.
Detailed explanation-2: -One strand of DNA run from 5’ to 3’ end while other run from 3’ to 5’ end, thus antiparallel in nature. The DNA strands are complementary to each other because of the nitrogenous bases as A only binds to T and C only binds to G.
Detailed explanation-3: -The strands of a DNA double helix are said to be “antiparallel” because the have the same chemical structure, but are opposite in direction.
Detailed explanation-4: -The strands of a DNA double helix are said to be “antiparallel” because they have the same chemical structure, but are opposite in direction.
