Question
“Naked” examples of these structures can dimerize into pairs known as “kissing complexes.” For 10 points each:
[10m] Name these secondary structures formed from the complementation of two sequences from different areas of the same RNA strand.
ANSWER: stem-loops [accept hairpin or hairpin loops]
[10e] Four stem-loops and a variable loop partly comprise this form of RNA responsible for bringing amino acids to a ribosome during translation.
ANSWER: tRNA [or transfer RNA]
[10h] Kissing complexes are examples of the loop-loop form of these structures. At least one stem-loop intercalates inside another stem-loop to form these structures, which were first recognized in the turnip yellow mosaic virus.
ANSWER: pseudoknots [accept loop-loop pseudoknots]
