Well DNA sequences are highly irregular. Also, the structures in cells work together extremely efficiently meaning they are non-random and clearly purposeful.
By highly irregular, I take it you mean they have a high degree of nonuniformity or variation. This is known as having high informational entropy according to Shannon's theory of information. According to which, such structures deviate from that which would be expected by chance. So this "highly unique" characteristic amounts to little more than a measure of how likely the structure is to occur by chance.
Anything can happen by random processes, it's only a matter of how likely they are to occur by chance. A horse could materialize in my living room. There's nothing preventing it from happening by chance, just that it's highly improbable. So the only thing you can realistically mean by "non-random" is too improbable to occur by chance. Again, this is just a judgement based on the probability of a structure occurring by chance.
I don't know what "clearly purposeful" means. Purpose relates to having a goal in mind. How you can say that any biological structure has a 'clear' end in mind is simply more question begging language. Perhaps structures have an end in mind, perhaps they don't. Regardless, the appearance of a thing does not in itself dictate that there is such an end in mind.
So what your criteria boil down to is saying that a particular biological structure is too improbable to have occurred by chance. But people who suggest abiogenesis and evolution are responsible for these structures aren't claiming that they occurred strictly by chance. So your criterion embed a false dichotomy between chance and design. Your criteria are little more than a claim as to how probable these structures could occur by natural process. Claiming that some structure is 'too unique' or 'non-random' is simply saying that you don't believe evolution and / or abiogenesis can account for them. That's nothing but unabashed incredulity. Your incredulity, or anyone's, isn't an objective feature of a biological structure. It's simply a subjective opinion.
