Removal of introns and joining the exons in a defined order in a transcription unit is called
  1. splicing
  2. tailing
  3. transformation
  4. capping

Solution

In some eukaryotes, genes consist of coding nucleotids sequences, which are separated from each other by blocks of non-coding sequences. The coding sequences here are called exons and non-coding sequences are called introns. The primary transcript from a typical eukaryotic gene contains introns as well as exons. The introns are removed from this primary transcript by a process called RNA splicing.
