Question
Recombinant DNA technology is used a. for gene therapy b. to clone a gene c. to make a particular protein d. all of the above are correct e. repetitive DNA Which of these is NOT needed to perform the cloning of an animal? a. sperm. from a donor male b. suspension in time for the nucleus and donor cell c. enucleated egg from a donor animal d. host female to develop the embryo e. all of the above are needed Gene therapy has been used to treat which of these? a. cystic fibrosis b. familial hypercholesterolemia c. severe combined immunodeficiency d. all of the above e. n clusters DNA fingerprinting with gel electrophoresis can be used for which of these? a. identifying human remains b. identifying infectious diseases c. finding evolutionary links between organisms d. solving crimes e. all of the above Chargaff found that DNA had special relationships between the bases. He observed that: a. A = C & T = G b. C = T & A = G c. A = T & G C d. CAT = DOGExplanation / Answer
57. option D:-all of the above are correct .reason :- R DNA means modification of gene of intrest,above all are involving modification of gene of intrest to perfom the particular function.
58.option A:- sperm from a donar male. reason :- the cloning was done only by the somatic cell not by the reproductive cell.
59. option D:- all of the above . reason:- gene theraphy means correction of abnormal gene sequence which leads to cause genetic disorders.above all are caused due to genetic disorder.
60.option D:- all of the above. reason:- in DNA finger printing separation of DNA bands based on the their density takes place , these bands helpful to compare with the suspected person DNA.
61. option C:- A=T&G=C. reason:- Chargaff's rules states that DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.
