170973 SCID or Severe Combined Immuno Deficiency Syndrome can be cured permanently by
I. Enzyme replacement therapy.
II. By SIRNA approach.
III. Introducing bone marrow cells producing ADA into cells at early embryonic stages.
(IV) By inserting the functional gene using retroviruses.
(V) Periodic infusion of genetically engineered lymphocytes having functional ADA, cDNA.

170975 The transgenic animals are those which have

1 foreign DNA in some of their cells
2 foreign DNA in all of their cells
3 foreign RNA in some of their cells
4 Both (A) and (C)
Biotechnology and its Applications

170978 The colonies of recombinant bacteria appear white in contrast to blue colonies of nonrecombinant bacteria because of :

1 Inactivation of glycosidase enzyme in recombinant bacteria
2 Non-recombinant bacteria containing betagalactosidase
3 Insertional inactivation of alpha-galactosidase in non-recombinant bacteria
4 Insertional inactivation of alpha-galactosidase in recombinant bacteria.
