Dimethyl sulfoxide (DMSO) is used as a cryopreservant for mammalian cell cultures because
Which one of the following is NOT a protoplast fusion inducing agent?
Determine the correctness or otherwise of the following Assertion (a) and Reason (r). Assertion: Plants convert fatty acids into glucose. Reason: Plants have peroxisomes.
Which one of the following amino acids in proteins does NOT undergo phosphorylation?
Determine the correctness or otherwise of the following Assertion (a) and Reason (r). Assertion: The production of secondary metabolites in plant cell cultures is enhanced by the addition of elicitors. Reason: Elicitors induce the expression of enzymes responsible for the biosynthesis of secondary metabolites.
Apoptosis is characterized by
Hypophosphatemia is manifested by an X-linked dominant allele. What proportion of the offsprings from a normal male and an affected heterozygous female will manifest the disease?
In nature, Agrobacterium tumefaciens mediated infection of plant cells leads to P. crown gall disease in plants Q. hairy root disease in plants R. transfer of T-DNA into the plant chromosome S. transfer of Ri-plasmid into the plant cell
Embryonic stem cells are derived from
Match the entries in Group I with the enzymes in Group II. Group I| Group II| | P. NAD+| 1. Glutathione peroxidase| | Q. Selenium| 2. Nitrogenase| | R. Pyridoxal phosphate| 3. Lactate dehydrogenase | | S. Molybdenum| 4. Glycogen phosphorylase|
The product commercially produced by animal cell culture is
HAT (hypoxanthine, aminopterin and thymidine) is used for selecting the hybridomas based on the following I. Only hybridoma will grow since it inherited the HGPRT genes from B-cells and can synthesize DNA from hypoxanthine. II. Myeloma cells will not grow in cultures since de novo synthesis is blocked by aminopterin and due to the lack of HGPRT enzyme.
Match items in Group I with Group II.

| 4. Amyloid | |
Determine the correctness or otherwise of the following Assertion (a) and the Reason (r) Assertion: In synchronous culture, majority of the cells move to next phase of the cell cycle simultaneously. Reason: Synchronous culture could be obtained by starving cells for essential nutrient components.
Match the herbicides in Group I with the target enzymes in Group II.
| Group I | Group II |
| P. Glyphosate | 1. Nitrilase |
