Select the incorrect statement regarding macromolecules found in cells.
Otrada [13]

Answer:

Explanation:

Ribonucleotides are repeating subunit of RNA while the deoxy-ribonucleotides are repeating subunits of DNA. That why RNA full form represent the ribonucleic acid and DNA represent deoxyribonucleic acid.

Actually the word "deoxy" means one oxygen is removed or less in DNA. The DNA  lacks the one oxygen atom of hydroxyl group at carbon number two of ribose sugar. While RNA have the hydroxyl group at carbon number two of hydrogen atom.

The removal of one hydrogen atom in DNA make it more stable than RNA because DNA is made specifically to store genetic information and needed to be strong. The oxygen atom in RNA makes it vulnerable for attack by other biological molecules.
