    If Tetracycline binds to the Ribosomes (its effectively like inhibition but its not enzymes in this case), the Ribosomes are unable to carry out their function which is to synthesise the proteins... Proteins make up enzymes, even the enzymes that are involved in the cell wall formation which can lead to Osmotic lysis as the cell wall is not formed.

    Second question:

    TTT TCA GGT ACG GAA CCA CGA

    TTT TCA GGT

    The next amino acid is Trp which is ACC which we can add:

    TTT TCA GGT ACC- What can you see base C has been added and we have been told in the question it is a result of mutation... This basically now shifts the reading frame of the sequence:

    TTT TCA ACC GGA ACC ACG
