Question

Fibrillarin methylates a precursor of this molecule within the dense fibrillar component. A famous electron micrograph taken by Oscar Miller showed that this molecule is synthesized in repeating units that resemble Christmas trees. (-5[1])The gene that encodes this molecule is the most common reference used in microbial metabarcoding. The anti-Shine–Dalgarno sequence is found in a conserved form of this molecule that Carl Woese (“woes”) sequenced to develop the three-domain system of classification. Chloramphenicol (-5[1])blocks the peptidyl transferase activity of this molecule. (10[1]-5[1])In eukaryotes, this molecule is transcribed by Pol I (“paul one”) in (-5[1])the nucleolus and assembled with proteins into the 40S and 60S subunits. For 10 points, name this most abundant type of cellular (-5[1])RNA, which forms (10[1])the structure that performs translation. ■END■ (10[4]0[3])

ANSWER: ribosomal RNA [or rRNA; accept 16S rRNA or 18S rRNA or 5S rRNA or 5.8S rRNA or 23S rRNA or 28S rRNA or SSU rRNA or LSU rRNA; accept small nuclear RNA or snRNA until “Christmas” is read, but reject afterward; prompt on RNA or ribonucleic acid; prompt on ribosome or small subunit or large subunit by asking “what molecule is that made of?”]
