Some of the following transgenic approaches could be used for functional characterization of endogenous genes in plants: (A) Transformation using a binary vector containing a strong enhancer element and lacking […]

In a gene stacking experiment, a transgenic plant generated using bar as a selection marker was crossed with another transgenic line containing hpt as the selection marker. Analysis of the […]

A single copy homozygous transgenic plant containing the transgene ‘A’ for fungal resistance was subsequently re-transformed with another gene ‘ B’ for conforming resistance to salt stress. The selection marker […]

Which one of the following statements is correct? (1) If a transgenic plant heterozygous for an insert segregates into 1:1 ratio for the transgenic phenotype on back-crossing then it contains […]

Which one of the following statements related to genetic transformation of plants is correct? (1) Negative selection markers need to be expressed only under strong constitutive promoter development of transgenic […]

ATO transgenic plant containing a transgene for herbicide resistance shows two bands on Southern blot analysis using a probe that is internal to the restriction sites used for genomic DNA […]

Given below are four statements regarding genetic transformation of plants in the laboratory: (A) Plants incapable of sexual reproduction cannot be transformed by Agrobacterium tumefaciens (B) Integration of transgene in […]

A transgenic plant having a homozygous single-copy insertion for trait A was re- transformed by Agrobacterium-mediated transformation with a gene conferring trait B. Given below are a few statements regarding […]

Given below are some statements that are associated with transgenic plants. Each statement has a blank space indicated by ‘_______’. A. A transgenic plant with two functional copies of a […]

A To transgenic plant contains two unlinked copies of the T- DNA of which one is functional and the other is silenced. Segregation of the transgenic to non-transgenic phenotype would […]
