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

    A)  splicing                               

    B)  tailing

    C)  transformation  

    D)  capping

    Correct Answer: A

    Solution :

    In some eukaryotes, genes consist of coding      nucleotides sequences, which are separate from             each   ther 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.
