Question

What is the structural consequence of RNA being single-stranded compared to DNA being double-stranded?

पर्याय

• RNA forms a flexible single-stranded chain with a sugar-phosphate backbone

• RNA is more rigid and stable than double-stranded DNA

• RNA cannot perform genetic functions

• RNA cannot form hydrogen bonds between bases

Answer 1

RNA is generally single-stranded, while DNA is usually double-stranded. The backbone of RNA consists of alternating ribose and phosphate groups, forming a flexible single-stranded chain that allows for the varied three-dimensional structures necessary for its functional roles in the cell.
