2015 AIPMT-I 1 question
-
A technique of micropropagation isMicropropagation produces thousands of plants through tissue culture.
In somatic embryogenesis, embryos develop from somatic cells in culture, which is a micropropagation technique.
2014 AIPMT 2 questions
-
In vitro clonal propagation in plants is characterized by:RAPD markers are suitable for detecting somaclonal variation.
-
To obtain virus-free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken:The meristems (apical and axillary) of an infected plant are free of virus, so they are removed and grown in vitro to obtain virus-free plants.
2012 AIPMT-PRE 2 questions
-
Which one of the following is a case of wrong matching?Callus, somatic hybridisation and micropropagation are all correctly described.
Vector DNA is a carrier DNA molecule (such as a plasmid) used to transfer a gene of interest into a host cell; it is not a site for tRNA synthesis.
So the vector DNA pair is wrongly matched. -
Which part would be most suitable for raising virus-free plants for micropropagation?Even when a plant is infected with a virus, its meristem (apical and axillary) is free of virus.
The meristem is removed and grown in vitro to obtain virus-free plants.

Somaclones are obtained byIn tissue culture, whole plants are regenerated from explants (any part of a plant) grown in a nutrient medium under sterile conditions; this capacity is called totipotency.
By micropropagation thousands of plants can be produced in a short time.
Each of these plants is genetically identical to the original plant from which they were grown; they are called somaclones.
Hence somaclones are obtained by tissue culture.
