protein synthesis - SB3 Flashcards
1
Q
what is the order of PS steps?
A
Transcription followed by Translation
2
Q
describe Transcription
A
The DNA code for a protein via bases remains in the nucleus -
A copy is made (called mRNA or messenger RNA) which travels to the ribosome
3
Q
describe Translation
A
mRNA arrives in the cytoplasm at the ribosomes-
ribosomes use the mRNA to match the base pairs in the ribosome-
the right amino acids are brought to the ribosomes in the correct order by carrier molecules
4
Q
how many amino acids are there?
A
20
5
Q
what happens when a chain of amino acids has been formed?
A
it folds into a unique shape which allows the protein to preform the task it’s meant to do
