WebIn the nucleus, a structure called a spliceosome cuts out introns (noncoding regions) within a pre-mRNA transcript and reconnects the exons. A spliceosome —a structure composed of various proteins and other molecules—attaches to the mRNA and “splices” or cuts out the non-coding regions. The removed segment of the transcript is called an intron.

WebIf the interaction between the nucleus and the neutron fails to produce subsequent neutrons, the process is considered a radiative or parasitic neutron capture. Usually a capture event produces an excited state in the nuclei, with a subsequent gamma emission to return the nucleus back to the ground state so the symbol ( n, γ) is used.
