Flashcards in Bio protein synthesis Deck (18):
1

transcriptional

premRNA complement copied from DNA

2

RNA processing

PremRNA-mRNA
(edited into shorter functional)

3

translation

ribosome reads mRNA to combine together amino acid

4

transcription detailed

RNA polymerase reads DNA template to make RNA complementary strand build fom 5'-3'

5

dicing/splicing

PremRNA has exon and intron (deleted by spliceosomes)

6

alternative splicing

intron can be used to form another mRNA
one gene= many mRNA

7

mRNA

5' cap added to 5' end
3' end: poly (A) tail

8

GTP

is attached to mRNA to provide energy to translation

9

start codon

AUG- methionine

10

stop codon

UGA, UAG, UAA

11

ribosome

has enzyme: ribozyme

large subunits
EPA
small subunit

12

A

aa landing site

13

P

polypeptide

14

E

exit

15

translocation

ribosome moves to the right

16

tRNA

acceptor stem, grabs spc aa

17

anticodon

present on tRNA attaches to complementary mRNA

18

translation inititaion complex

aa
trna
ribo
mRNA
