translation

Question 1

where does translation occur?

Answer 1

cytoplasm, specifically on the ribosome

Question 2

what does translation do?

Answer 2

he process of decoding the information in messenger RNA (mRNA) to synthesise a polypeptide chain, with the help of transfer RNA (tRNA). This chain then folds into a functional protein.

Question 3

what is the first step of tranlsation?

Answer 3

ribosome attaches to the mRNA strand at a start codon (AUG).

Question 4

what type of molecule has a anticodon?

Answer 4

tRNA

Question 5

what is the second step of translation?

Answer 5

a tRNA molecules with a specific amino acid and anti codon that is complementry to the strat codon binds to the mRNA

Question 6

what is the third step of translation?

Answer 6

A second tRNA molecule with an anticodon complementary to the next mRNA codon, and also carrying a specific amino acid, attaches to mRNA.

Question 7

what is the fourth step of translation

Answer 7

The amino acids carried by the first two tRNA molecules are linked together via a peptide bond using ATP.

Question 8

what is the fifth step in tanslation?

Answer 8

The first tRNA molecule detaches from mRNA and is free to collect another amino acid for future use.

Question 9

what is the sixth step of translation?

Answer 9

The ribosome moves along mRNA, allowing another tRNA molecule, which carries the next amino acid, to bind to the next codon on the mRNA.

Question 10

what is the seventh step of translation?

Answer 10

The process from step 4 to 6 is repeated, which elongates the polypeptide chain.

Question 11

what is the eighth step of translation?

Answer 11

The sequence continues until a stop codon on the mRNA is reached, at which point the completed polypeptide chain detaches from the ribosome
