Title: Why is DNA said to be antiparallel?
Post by: dracko on Nov 15, 2017
Why is DNA said to be antiparallel?
A) The two strands of DNA are joined together via complementary base pairing such that AT run in the 3'5' direction and CG run in the 5'3' direction.
B) The DNA strands twist into a helix conformation once the bases have joined to form major and minor grooves.
C) Each strand of the double helix is made up of a sugar phosphate backbone which runs in the 5'3' direction.
D) DNA has polarity such that one strand runs in the 3'5' direction and the other in the 5'3' direction.
