Translation

Question 1

Describe the structure of tRNA

Answer 1

Sections of tRNA sequence of complimentary and so form weak hydrogen bonds which result in a clover like structure

Question 2

What is step one of translation?

Answer 2

A ribosome binds to the mRNA at the AUG start codon

Question 3

What is STEP2 of translation?

Answer 3

The genetic code on the mRNA is ready in groups of three letters called codons

Question 4

What is step three of translation?

Answer 4

TRNA molecules have specific anti codon for each of the 20 amino acids

Question 5

Step four of translation

Answer 5

The complimentary anti codon is attracted to the first codon on the mRNA and forms, weak hydrogen bonds

Question 6

What is step five of translation?

Answer 6

The secondary codon on mRNA also attracts its complimentary anti codon on tRNA

Question 7

What is step six of translation?

Answer 7

A condensation reaction forms peptide bonds between the adjacent amino acids

Question 8

What is step seven of translation?

Answer 8

The first tRNA molecule becomes detached from its amino acid

Question 9

Step eight of translation

Answer 9

The ribosome moves along the mRNA molecule

Question 10

Step nine of translation

Answer 10

The polypeptide chain gradually grows until the ribosome reaches a stop codon and releases the mRNA

Question 11

Step 10 of translation

Answer 11

The polypeptide chain can then fold into a unique 3-D confirmation
