There is more than one way to splice an RNA transcript.
Two different genes can produce the same RNA transcript, which will then be translated differently.
It does so by varying the rate at which it is broken down in the cytoplasm.
There is more than one way to modify the coded polypeptide.
It does so by varying the length of its tail.
