Silent mutation and third position

    I got this question in an exam. Why do silent mutations always affect the third position of a codon? I have no clue about it.

    A quick google gave me some information on this, have you had a look?

    They don't always affect the third position, but they are definitely more common at the third position. Read up on how tRNAs recognize codons during translation.

    The search keywords "wobble base" might help.

    I'm sorry I didn't do my research properly before posting this question. @pinball1970

    Thanks to both of you. @JonMoulton & @Ygggdrasil
