    The question really doesn't make that much sense.

    I don't know their structure but knowing the theory behind primary secondary and tertiary structure... RNAase sounds like an enzyme to me (I don't do Biology at A2). So... an all RNAase molecules will have the same chemical formula, same arrangement therefore same polypeptide chain sequences and same tertiary structure.

    From the question I can assume that you had identical original molecules of RNAase and something happened to them to cause them to change tertiary structure (heating maybe?). You need to put the question in context.

    Explain why all the original molecules of RNAase had the same tertiary structure
    Because they came from the same source maybe? Same organism / same can / same processes used to make all of them?

    Really, it's like asking "explain why all the molecules in this tank of methane have the same chemical formula".

    Hope my answer helps even a bit.

    yea thats because they're the same type of enzymes! All RNAases have a similar strcture because they comprise the same number, type & sequence of amino acids in their polypeptide chains...in other words a primary sturcture unique to that of RNAase; hence they undergo the same irregular bending & folding...

    Aye and furthermore for the polypeptide to actually be an RNAase, it must have a very specific active site. As the shape of this active site is dependent on the tertiary structure, it follows that the tertiary structures must be the same.

    Reference to "R-groups" is important
