PGDDE,Ph.D                                  Vice Principal RJ College(CSN) Define Transposons ? Describe types and importance of transposons (15 marks) Def : The sequences of DNA that can move or transpose themselves to new positions within the genome of a single cell are called Transposons.      Transposons is a class of genetic elements that can jump to different locations within a genome. Transposons are called jumping genes.Transposons were first discovered in corn (Zea mays- Maize) in 1948 by American scientist Barbara McClintock whose work won her noble prize for physiology or medicine in 1983. ...

  BOT 103   MSc I   CYTOGENETICS   &   MOLECULAR   BIOLOGY CH 1. Cytogenetics : Definition, history and   application in Biology                  Prof. Dr. Sadhana Nikam                  M.Sc , B.Ed, PGDDE, Ph.D Definition of cytogenetics : A branch of biology which deals with the study of   heredity   and variation by the methods of both cytology and genetics is called Cytogenetics.   *Cytogenetics is a branch of genetics. * It is also a part of cell biology or cytology. *It is concerned with how the chromosomes relate to cell behaviour, particularly during mitosis and meiosis. *Techniques used include karyotyping, analysis of G-banded chromosomes, other cytogenetic banding techniques. * molecular cytogenetics such as fluorescent in situ hybridization (FISH) and comparative genomic hybridization (CGH).   History : 1.Rob...
