Question

you can observe the main differences between dna and rna by clicking on the view image button. which statement is true? a) rna is more stable than dna b) dna has no hydroxyl group on the second carbon c) rna bases are a, t, c, g d) only dna has a phosphate backbone

Explanation:

DNA is deoxy - ribonucleic acid, where "deoxy" means it lacks a hydroxyl group on the 2' carbon of the sugar ring. RNA is ribonucleic acid with a hydroxyl group at the 2' carbon. DNA is more stable than RNA. RNA bases are A, U, C, G (not T). Both DNA and RNA have a phosphate - sugar backbone.

Answer:

B. DNA has no hydroxyl group on the second carbon
