Removal of introns and joining the exons in a defined order in transcription unit is called

  • splicing

  • tailing

  • transformation

  • capping

Solution

A.

splicing

In some eukaryotes, genes consist of coding nucleotides 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.
