DNA - Translation

Question 1

translation

Answer 1

• the decoding of an mRNA message into a polypeptide chain

- aka: protein synthesis

Question 2

where does it happen?

Answer 2

• tales places on the ribosomes

- mRNA is transcribed in the nucleus, then enters the cytoplasm and attaches to a ribosome

Question 3

the role of tRNA

Answer 3

• the mRNA molecule moves through the ribosome and the tRNA molecule ‘translates” the codon and brings the proper amino acid
• the part that reads the codons are called anticodons
• the amino acid is added to the growing polypeptide chain

Question 4

start and stop codons

Answer 4

• tells the tRNA molecule where to start and stop translating
• AUG - start codon
• UAA, UAG, UGA - stop codons
• release the finished chains into the cell to do its job

Question 5

anticodon

Answer 5

• group of three bases on a tRNA molecule that are complementary to an mRNA codon
• anticodon tells the tRNA molecule where to attach itself
