Question 2 (1 point)
A mutation in hemoglobin can cause severe disease, because it is the protein that is
responsible for carrying oxygen throughout the body. A sick patient could be born
with a change in the DNA that codes for hemoglobin synthesis. The nucleotides in
the DNA, in the region that codes for the order of amino acids in the protein, was
changed at position 6 from GAG to GTG. How could this cause the disease?
The ribosome made a mistake.
The DNA was transcribed incorrectly.
The change affected breathing, causing a lack of oxygen.
The instruction in DNA sent the hemoglobin to the wrong location.
The wrong amino acid was used at position 6, which produces a nonfunctional
hemoglobin.
