Question

Amniocentesis is a technique used to
A. Determine errors in amino acid metabolism in embryo
B. Pinpoint specific cardiac ailments in embryo
C. Determine any hereditary genetic abnormality in embryo
D. All of these

Answer 1

Hint: Amniocentesis is a medical treatment used to diagnose chromosomal abnormalities, fetal infections, and determine sex during pregnancy. In this procedure, a little amount of amniotic fluid containing foetal tissues is extracted from the amniotic sac surrounding a developing foetus. The foetal DNA is then examined for any genetic abnormalities.

Complete answer :
Option A Determine errors in amino acid metabolism in embryo : Amino acid metabolism disorders are uncommon diseases that disrupt the body's metabolism. Certain amino acids can't be broken down by people with certain illnesses. This might lead to the accumulation of toxic compounds in the body. This disease can be diagnosed by analyzing amino acid concentrations in body fluids. Amniocentesis is not used for this; hence option A is not correct.
Option B Pinpoint specific cardiac ailments in embryo : The most common method for diagnosing cardiac illness in the foetus is ultrasonography; however, newer technologies such as magnetic resonance imaging, foetal electrocardiography, and magnetocardiography are now available. Amniocentesis is not used for this purpose. Hence, option B is not correct.
Option C Determine any hereditary genetic abnormality in the embryo : Amniocentesis is a procedure that involves the removal of amniotic fluid from the uterus for testing or therapy. This is a prenatal test that can be used to determine genetic diseases (including Down syndrome and spina bifida) as well as other health problems during pregnancy. Hence, option C is the correct answer.
Option D All of these : Since only option C is correct, option D is wrong.

Hence, option C. Determining any hereditary genetic abnormality in embryo is the correct answer

Note :
Amniocentesis can be done to assess the development of a fetus's lungs. Infant respiratory distress syndrome can be exacerbated by problems with lung development. The amount of surfactant in the amniotic fluid can be used to assess foetal lung development. The lecithin-sphingomyelin ratio ("L/S ratio"), the presence of phosphatidylglycerol (PG), and the surfactant/albumin (S/A) ratio are among the tests available.
