5.4 translation and mutations

Question 1

codon

Answer 1

every 3 letters in our mRNA that codes for 1 amino acid

Question 2

start codon

Answer 2

AUG

Question 3

code is all

Answer 3

life

Question 4

serval codes for each amino acid

Answer 4

true

Question 5

anticodon

Answer 5

3 base sequences pair with codons

Question 6

order of translation

Answer 6

DNA,mRNA, Ribosome, site of protein synthesis

Question 7

mRNA role

Answer 7

contains messages/code for the amino acid sequence

Question 8

tRNA role

Answer 8

transfers amino acids, contains anticodons that pair with mRNA codons to put a.a in correct order

Question 9

rRNA role

Answer 9

facilitates the matching of mRNA and tRNA

Question 10

role of aminoacyl tRNA synthetase

Answer 10

puts animoacyl & tRNA together

Question 11

a site

Answer 11

aminoacyl tRNA site matches the correct incoming tRNA to the next codon in the mRNA

Question 12

p site

Answer 12

peptidyl tRNA site- holds tRNA carrying growing polypeptide chain

Question 13

e site

Answer 13

exit site- empty tRNA leaves ribosome from exit site

Question 14

point mutation

Answer 14

substitiuon of a sigle base

Question 15

silent mutation

Answer 15

change in DNA but doesn’t change amnio acid

Question 16

missense

Answer 16

changes in amino acid

Question 17

nonsense

Answer 17

cahnges to stop codon

Question 18

frameshift insertions

Answer 18

adding bases

Question 19

deletions

Answer 19

losing bases
