Exam points
- state that the gene remains in the nucleus while an mRNA copy is made
- trace mRNA from the nucleus to a ribosome in the cytoplasm
- explain that ribosomes assemble amino acids in the order specified by mRNA bases
17.1.8—Protein is made question 1
[Maximum number: 2]
A gene is involved in the production of the enzyme alcohol dehydrogenase.
Describe the role of ribosomes in the synthesis of proteins such as enzymes.
mRNA passes through ribosomes ; ribosomes assemble amino acids into proteins ;
order of amino acids is determined by the sequence of bases in mRNA ;
