Removal of introns and joining of exons in a defined order during transcription is called
A
looping
B
inducing
C
slicing
D
splicing.
(AIPMT-2012)
Solution
(d) : Introns, which occur principally in eukaryotes, are transcribed into messenger $RNA\ (mRNA)$ but are subsequently removed from the transcription before translation. In certain cases, removal of the introns is an autocatalytic process (self splicing) whereby the $RNA$ itself has the properties of an enzyme.
