Question

which of the following nucleotide sequences might be found in an RNA molecule that forms a secondary structure of a stem with no loop?

Answer 1

One possible nucleotide sequence that could form a secondary structure of a stem with no loop in an RNA molecule is an internally complementary sequence near the 3' end of the transcript.

Step-by-step explanation:

A stem with no loop in an RNA molecule refers to a hairpin structure where the RNA folds back on itself and forms intramolecular hydrogen bonds between complementary nucleotides. In this case, the nucleotide sequence will have a specific pattern. One possible nucleotide sequence that could form a secondary structure of a stem with no loop is an internally complementary sequence near the 3' end of the transcript, which folds to form a secondary hairpin loop structure.
