A group of three bases in mRNA are known as a

• gene

• triplet

• codon

• amino acid

Organize these statements into the right categories

Groups:

(a) mRNA

,

(b) ribosome

,

(c) tRNA

,

(d) protein

• site of protein synthesis

• attaches to a ribosome

• brings amino acids to ribosome

• uses anticodon to match with mRNA codon

• carries DNA code as a codon

• is made of amino acids

• found outside the nucleus in the cytoplasm

• is made in the ribosome

Place these steps of protein synthesis in the correct order.

• DNA code is copied into mRNA

• mRNA attaches to a ribosome

• tRNA brings amino acids to the ribosome

• amino acids bind together to form a protein

• mRNA leaves nucleus and travels to a ribosome
