Answer:
B
Explanation:
Ribosenucleic acid (RNA) and Deoxyribosenucleic acid (DNA) are the two nucleic acids formed from building blocks called nucleotides. Although, they are formed from the same building blocks, but have structural differences.
One of the differences between RNA and DNA is that unlike DNA that is a double-stranded molecule formed by the complementary base pairing of two nitogenous bases (nucleotides), RNA is a single-stranded molecule made up of shorter nucleotides.
It is a strong cell in the human body that engulfs small cells and bacteria.
