    Ok, I have a seen question for a resit im about to sit and i cant for the life of me work it out. The question is:

    What is the link between tetracycline and streptomycin, amatin and ricin and DNA
    (I think she meant alpha amanitin)

    Now, I know streptomycin blocks bacterial ribsomes, the same as tetracycline.
    As does ricin, only in eukaryotic ribosomes.

    Alpha-amanitin inactivates RNA polymerase II.

    and i have no idea where on earth DNA fits in to this....

    Really any help at all would be greatly appreciated, im going crazy here!

    - All the drugs you mention inhibit protein synthesis
    - Less protein synthesis causes less of the enzymes required for DNA replication
    - (e.g. less DNA polymerases, DNA ligase + helicase...ect.)
    - And so they indirectly inhibit DNA replication

    HTH... good luck with the retakes mate...
