Neighbour, you really are talking about physics not chemistry with that question. Generally Chemistry deals with chemical interactions between
substances, and Physics with those inside them.
But ok, really> You want to talk about atomic physics. Sure why not. But first ask a question.
At approximately element 173 it becomes almost impossible based on its sequence and environment to predict the tertiary secondary and quaternary
structure of a polyribonucleic acid sequence?
is a statement, thus the question mark is is not needed. Unless you are not sure of what you just
said? You then shoe horn in something about RNA. No citation.
So you most certainly not asking what the element is. It is nothing, its a hypertheoretical element. We've not made, gotten close to making, and most
likely will never make. We don't know. Ohg and you did not really read the wiki you were posting in. Because other predictions (its all theory till we
get there, if we get there) say z=128 or 15 5may be the end of the periodic table, and others say it will keep going. So WHICH model are you using for
Z=173, and what does that mean about electron configurations?
So this is not basic Chemistry or Biochemistry or Physics. It is theoretical. Cite me the source, and I will talk to it. Unlike Coop not really
answering bog standard mechanistic Organic chemistry basics, this is specific. But like I said, show me the source, I may comment. Oh and it will be
200% theorietical, so don't pretend otherwise.
You then for some reason decided to talk about Nucleic acid structures. Which any biochemist can talk too.
Primary structure is the actual linear sequence of the nucleotides. So AGCCCGA for example.
Secondary structure is basep airing interactions. Its essentially hydrogen bonding. Though DNA and RNA are different, due to the extra hydroxyl group
in the ribose sugar. That is chemistry. Its non convalent (and weak) bonding.
Tertiary structure is how the chain of nucleic acids fold in space (a 3D map).
Quarternary structure is interactions between the nucleic acids and the nucleic acids and proteins.
This is all very similar to the same ideas for other macromolecues, like oh Proteins.
So can you phrase your question clearly?
