Protein Synthesis

Question 1

Where does transcription happen?

Answer 1

In the nucleus

Question 2

Where does translation happen?

Answer 2

Ribosomes/rough ER

Question 3

How does STOP prevent more amino acids joining on?

Answer 3

Doesn’t carry any amino acids so the chain can’t continue

Question 4

Stage 1

Separate

Answer 4

DNA strands separate in the nucleus

Question 5

Stage 2

Pair, RNA nucleotides

Answer 5

Exposed DNA bases from one of the strands pair with bases from RNA nucleotides

Question 6

Stage 3

RNA polymerase, Phosphodiester

Answer 6

RNA polymerase joins RNA nucleotides together with Phosphodiester bonds

Question 7

Stage 4

Gene

Answer 7

Transcription continues until the end of a gene.

Question 8

Stage 5

Splicing

Answer 8

Introns are spliced out of the mRNA

Question 9

Stage 6

Pores

Answer 9

mRNA molecules leave the nucleus through the nuclear pores

Question 10

Stage 7

Ribosomes

Answer 10

mRNA molecules join to ribosomes

Question 11

Stage 8

tRNA

Answer 11

tRNA molecules carry specific amino acids to the ribosomes

Question 12

Stage 9
(Codons)

Answer 12

Codons on mRNA pair with complementary anti codons on tRNA

Question 13

Stage 10

Peptide bonds

Answer 13

Adjacent amino acids are joined by peptide bonds

Question 14

Stage 11

Folding

Answer 14

The protein produced then folds into the correct shape
