    I get that it's to remove introns, but what effect would not removing these introns have on the translation process?

    So if you consider that the mRNA sequence is read in batches of 3 nucleotides this should provide you with your answer.

    Obviously you are aware that introns are non essential, non-coding sequences of DNA. These useless pieces of script are removed in order to allow for reading of the correct protein sequence which will in turn give rise to the correct protein. Consider the following sentence:

    THEHGECATYYUANDHPODOGTHLRAN

    By reading the sentence as a whole it does not make any sense. However if we read the triplets after removing the junk parts or “introns” then it reads:

    THE CAT AND DOG RAN

    So what we have done is remove the necessary parts so that the sequence is the correct one for the mRNA and thus producing the right polypeptide. If these introns were left in, then the final product would contain extra unnecessary nucleotides therefore giving the wrong message.
