What is the structural feature that forms when short regions of RNA form base pairs?
A
Linear strand
B
Triple helix
C
Double helix similar to DNA
D
Hairpin loop
Verified step by step guidance1
Understand that RNA, like DNA, can form structures through base pairing, but RNA is typically single-stranded.
Recognize that when short regions of RNA form base pairs, they can create secondary structures.
Identify that one common secondary structure in RNA is the 'hairpin loop,' which occurs when a single strand folds back on itself and base pairs with a complementary section.
Visualize the hairpin loop as a stem-loop structure, where the 'stem' is the double-stranded region formed by base pairing, and the 'loop' is the unpaired region at the top.
Note that this structure is different from a linear strand, which does not involve folding, and from a triple helix, which involves three strands.
