To answer this question we need to analyze each available option:
A. An angiogram. Is a procedure used to obtain x-ray images showing blood vessels of the heart as well as blood flux. So this is the correct answer.
B. Electroencephalogram. This is a study of the cerebral function based on its electric activity. So this cannot be.
C. Amniocentesis. Refers to a pregnancy test to diagnose genetic disorders in a fetus, using amniotic fluid, so this cannot be either.
D.. An echogram, which refers to an image created by sound waves of high energy, is an ultrasound so this cannot be.
Tay-Sachs destroys nerve cells in the brain & spinal cord. Pku is a birth defect that causes amino acids to build up in the body. They are similar because you can get seizures from both & in both there is also slow growth.
Before answering the question, you should know that exons/intron systemin the gene exists only in eukaryotes. A gene can have many exons with introns between them, but in RNA maturation, these exons will be joined together to form one RNA to code for one protein (There's no relation between exons number and how many proteins are formed).
In prokaryotes it is different there's no exons/introns, but their gene can be transcripted to a polycistronic RNA which can give after translation more than one proteins.
