Question 23

What does the order of bases in a gene decide about the protein that the gene codes for?

  1. The amount of the protein that is made
  2. The order of the amino acids in the proteinCorrect answer
  3. The speed at which the cell makes it
  4. Nothing, because one base codes for one whole protein

Explanation

A gene is read as a sequence, and that sequence sets the sequence of amino acids joined together to build the protein. How much protein appears is controlled separately by how strongly the gene is switched on, so a change in base order alters what the protein is rather than how much of it is present.
