RNA Structure and Types — Flashcards

_____ are small, noncoding RNA molecules that post-transcriptionally regulate protein expression. The 3' UTR of target mRNAs contains sequences determining their specificity.

DNA & RNA are made of _____ connected via a phosphodiester bond

Non-canonical DNA and RNA segments are formed as a result of _____

RNA polymerase _____ makes rRNA

Xanthine is converted to _____ by xanthine oxidase

One co-transcriptional modification is the addition of a _____ at the 5' end

Hypoxanthine is converted to _____ via xanthine oxidase

microRNA often leads to the _____ of target mRNA, thus causing decreased translation into protein

Guanosine is converted to _____ via the enzyme purine nucleoside phosphorylase (purine salvage)

Inosine is converted to _____ via the enzyme purine nucleoside phosphorylase (purine salvage)
