A neonatally thymectomized mouse, immunized with protein antigen, shows
A roller-bottle culture vessel, cylindrical (r = 10 cm, l = 20 cm), is fitted with a spiral film (L = 30 cm, w = 20 cm). If the film can support 10⁸ anchorage-dependent cells per cm², the increase in surface area and additional number of cells that can grow are

An example for template independent DNA polymerase is
An immobilized enzyme being used in a continuous plug-flow reactor exhibits an effectiveness factor (η) of 1.2. The value of η being greater than 1.0 could be apparently due to
Antibiotic resistance marker that CANNOT be used in a cloning vector in Gram-negative bacteria is
Determine the correctness of the Assertion (A) and the Reason (R): Assertion: Somatic embryogenesis in plants is a two-step process comprising embryo initiation followed by embryo production. Reason: Embryo initiation is independent of the presence of 2,4-D whereas embryo production requires a high concentration of 2,4-D.
Determine the correctness of the following Assertion (A) and Reason (R): Assertion: MTT assay is used to determine cell viability based on the principle of colour formation by DNA fragmentation. Reason: MTT assay is used to determine cell viability based on colour development by converting tetrazolium soluble salt to insoluble formazan.
