1.	Mohan's wife is pregnant for the last four months. He took his wife to gynacologist for routine check up. After check up the doctor suggested his wife to undergo amniocentesis test in order to know the genetic disorder, if any in the foetus. After performing amniocentesis test the doctor advised for PCR test so as to confirm the presence of genetic defect in the foetus. After coming back home Mohan's wife discussed this matter with her mother in law, who denied her to undergo, such tests and told that two much such tests may harm the baby. Answer the following questions on the basis of above informations. (i) What is amniocentesis? (ii) What do you understand by PCR. Explain briefly its uses. (iii) Do you think that Mohan's mother is justified in her behaviour ?
Answer» (i) Amniocentesis is a prenatal diagnostic technique used to determine sex and genetic disorder of an unborn foetus. (ii) PCR stands for polymerase chain reaction. This technique is used to amplify selected sequences of DNA so as to facilitate the genetic diagnosis of diseases such as sickle cell anaemia, muscular dystrophy etc. PCR is also used in the detection of HIV, DNA finger-printing, it is also used to clone DNA fragments extinct animals. (iii) No Mohan's mother is not justified denying for the tests to be conducted. Amniocentesis and PCR test are primarily meant for finding out the genetic disorders in the developing foetus. They do not harm the developing baby. If the foetal genetic defects are confirmed by the tests the termination of such and pregnancy is not illegal.
