Packet 9: Bonus 18
The ability of some of these molecules to replicate themselves lends credence to their namesake “world” hypothesis, which posits that life began as these molecules. For 10 points each:
[10e] Name these molecules whose “transfer” and “messenger” varieties are involved in the translation of proteins.
ANSWER: RNA [or ribonucleic acid; accept tRNA or mRNA]
[10m] Transfer RNA contains a “pseudo-” form of this nitrogenous base. RNA contains this nucleobase, not typically found in DNA, which forms two hydrogen bonds with adenine.
ANSWER: uracil [or uridine; prompt on U]
[10h] This structure largely made of RNA performs a namesake process that removes introns from pre-messenger RNA. This complex is synthesized from snRNPs (“snurps”).
ANSWER: spliceosome (“SPLICE-uh-sohm”)
