Explanation / Answer
Answer=
The correct statement about DNA strand structure is
The backbone is composed of alterating sugars,bases and phosphates.
explaination- The backbone of DNA consists of sugars ,bases and phosphates.
The 5'end of DNA means 5'carbon has a phosphate group attached to its and 3'carbon has hydroxyl group.
The bases are stabilized by hydrogen bonds in between nitrogenous bases.
