1. Contribution to regulation of gene
What are the activity
three main 2. Diversity - many different RNAs
benefits to RNA can be produced from one gene via
processing? alternative splicing
3. Quality control
,Many of the RNA protein, RNA, RNPs
processing
complexes
contain both
_______ and ___
components.
Give an
example.
An E. coli 3, several
precursor
encodes __
rRNAs and __
tRNAs.
The S. cerevisiae 3
precursor
encodes __
rRNAs.
Why is encoding ensures that similar amounts of each
several RNAs in RNA are made
one precursor
beneficial?
,True or False: False, go both ways
Exonucleases
operate strictly
in the 3' to 5'
direction during
RNA processing.
Give two RNase III and RNase P
examples of
endonucleases.
5' trimming of RNase P
tRNAs is done
by which
endonuclease?
True or False: False: Only bacterial can cut alone
Both the
bacterial and
eukaryotic RNA
component of
RNase P can cut
RNA alone
, True or False: True
Some rRNA
introns can
catalyze their
own removal
and are
subsequently
called self-
splicing.
What is the CCA It is the attachment site on the tRNA
sequence? for the amino acid
What are the two 1. ribose 2'-O-methylation
most common 2. pseudouridylation
rRNA
modifications?
True or False: False: Modifications can be small,
Post- like methylation, but can also be
transcriptional large, like the addition of a threonine
chemical
modifications
are limited to
small additions
such as
methylation
