An rRNA binds to a snoRNP that contains a C/D box snoRNA.What type of covalent modification would you expect this rRNA toundergo? Would it be methylated or pseudouridylated, or both?

A newly identified protein from the  cells of the Panopyra plant on Pandora was shown to inhibit translation of its target genes by binding to the 5’ UTR of the mRNA and preventing ribosome binding.  A possible way this inhibition may be relieved by an sRNA would be:  Group of answer choices a)The sRNA acts as a silencer, suppressing the inhibitory protein and allowing translation to take place. b)The sRNA acts as a decoy, sequestering the inhibitory protein and allowing translation to take place. c)The sRNA acts as a marker, flagging the inhibitory protein for ubiquitination and allowing translation to take place.

A double-stranded RNA has been generated by release/splicing out of an intron within the nucleus...outline the pathway taken to generate microRNA and its  action on the shutdown of protein biosynthesis

1. a)What are the two types of ncRNA used in translation?  b.) How is translation terminated when the ribosome reaches a stop codon?

The diagram, shown in attatched image, shows an mRNA that is alternatively spliced. The alternatively spliced variant contains Exon 1, Exon 2, and Exon 4. Indicate below if a splice site is used, blocked by a modifying protein such that the spliceosome must choose a different site, or skipped to make this alternatively spliced variant.
