e. Many genes contain the information needed for cells to synthesize enzymes and other proteins.
Which of the following is true regarding understanding the results of genetic testing?
A.
If the test shows that you have the allele for a genetic disorder, you may be able to reduce your risk of developing that disorder with lifestyle changes.
B.
If the test shows that you have the allele for a genetic disorder, you will, eventually, show symptoms of that disorder.
C.
Because we know the functions of all the genes in the human genome, genetic tests can give you complete and accurate information regarding your medical health.
D.
If the test shows that you do not carry the allele for a particular disorder, there is no chance that you will get that disorder.
