A) cistron
B) transposon
C) intron
D) recon
Correct Answer: B
Solution :
Transposon is a DNA segment or genetic element moving from one chromosome to another. The term, was introduced by R W Hedges and A E Jacob in 1974, to controlling elements or jumping genes, discovered by Barbara McClintock (1950) in maize. Cistron is the functional unit of DNA molecules, it codes for a particular gene product. Recon is the cross-over unit or it is segment of DNA which participates in crossing over. Introns are the interrupted genes or those regions of a gene which do not form the part of mRNA and are removed from primary mRNA during gene expression in eukaryotes. These are non-coding sequences which get removed during splicing and processing.You need to login to perform this action.
