Attempt

1 of 3

Drag and drop the boxes into the correct order.

Put these stages of protein synthesis in order

A ribosome attaches to mRNA and reads the first triplet of the base sequence
The ribosome reaches a stop codon and detaches
Further amino acids are brought to the growing polypeptide chain
Pre-mRNA is spliced into mRNA containing only exons
An enzyme unwinds the double helix of DNA
A tRNA molecules carries an amino acid to the corresponding exposed codon
RNA polymerase joins nucleotides that have formed complementary base pairs with a template strand

This is your 1^st attempt! The marking algorithm gives more marks for getting the right order first time.
