Question

What is meant by the term ‘DNA polarity’?
	One end of DNA has a 5’ phosphate group while the other end has a free 3’ hydroxyl group.DNA was first discovered at the North Pole.One side of DNA has the phosphate backbone while the other side has the nucleotide bases.There are many polar covalent bonds in DNA.

Answer 1

DNA polarity:

One end of DNA has a 5’ phosphate group while the other end has a free 3’ hydroxyl group.

Explanation:

Double-stranded DNA is a right-handed helix formed by the two individual DNA strands aligned in an antiparallel

Antiparallel DNA has the two strands organized in the opposite polarity, with one strand oriented in the 5′-3′ direction and the other oriented in the 3′-5′ direction.
