Protein Synthesis Flashcards
1
Q
central dogma
A
info flows from DNA to RNA to protein
2
Q
transcription
A
flow of info from DNA to RNA occurs in nucleus
3
Q
three steps to transcription
A
initiation, elongation, termination
4
Q
initiation
A
RNA polymerase identifies where promoters are, DNA unzipped
5
Q
elongation
A
RNA polymerase adds complimentary RNA nucleotides
6
Q
termination
A
RNA polymerase stops transcription at terminator in DNA sequence
7
Q
translation
A
decoding message in mRNA to assemble amino acids
8
Q
crick and bremer
A
determines mRNA is read in sets of 3 (codon)
9
Q
how many codons
A
64
10
Q
how many amino acids
A
20
11
Q
start codon
A
AUG methionine
12
Q
stop codons
A
UUA UGA UAG
13
Q
mRNA
A
carries code from DNA to ribosomes
14
Q
rRNA
A
holds ribosomal complex together
15
Q
tRNA
A
carries amino acids to ribosomes (anticodon complimentary to codon)
