Flashcards in Lec 30 - RNA Processing / Splicing Deck (15):
1

two subunits of rRNA is eukaryotes

60s, 40s

2

rRNA size in eukaryote

80s

3

rRNA size in prokaryotes

70s

4

in prokaryotic rRNA processing, blank is cut out in two places

tRNA

5

this protects the 5' head of the mRNA

capping

6

capping involves blank

methylation

7

5' and 3' ends are both protected from blank

exonucleases

8

these are cut out when splitting

introns

9

these stay when splitting

exons

10

a lariat is formed by blank in rna splicing and is eventually degraded

intron

11

splicing only occurs in blank

mRNA

12

mRNA can not perfectly reflect blank because it has some of the missing parts

dna

13

when you splice a gene into different sections they can have very different functions

alternative splicing

14

in the intestine a blank is switched to blank which creates a stop codon and is called blank

c, u, rna editing

15

two subunits of rRNA in prokaryotes

50S, 30S
