5.4 translation Flashcards
1
Q
codon
A
every 3 bases in mRNA
2
Q
anticodon
A
3 base sequences that pair with codon on mRNA
3
Q
mRNA
A
contains code for amino acid sequence
4
Q
tRNA
A
transfers amino acids to ribosomes, contain anticodon that help put amino acids in order
5
Q
rRNA
A
facilitates matching of mRNA & tRNA makes proteins
6
Q
A-site
A
matches correct t-RNA to the next codon in the mRNA
7
Q
P-site
A
holds growing polypeptide chain
8
Q
E-site
A
empty tRNA leaves ribosome
9
Q
mutation
A
change in the base sequence in a molecule of DNA
10
Q
when do mutations happen?
A
DNA replication
11
Q
point mutation
A
substitution of single base
12
Q
silent mutation
A
no amino acid change
13
Q
missense
A
change amino acid
14
Q
nonsense
A
change to stop codon; short protein or no protein
15
Q
insertions
A
adding bases
