Answer 2

If you want to talk about biochemical molecules, you will realize that that structure and function go hand in hand.

What is advantagious about the pores? Well what does it allow the RNA ... TO DO? (i.e. what will be the function).

DNA ---> RNA ---> protein

DNA (in the nucleus, nice and protected) makes short copies of itself in the form of RNA. It does this because it is activating instructions via RNA to make proteins, send messages, etc. The DNA essentially "manages" everything that goes on inside the cell. In order for RNA (the message) to go forth and do as the DNA instructs (per which genes are active, etc), IT MUST BE ABLE TO LEAVE THE SAFE NUCLEUS.

None of the organelles that carry out the DNA's instructions are inside the nucleus. They're not allowed in, in part, because DNA is fragile. There are thousands of enzymatic reactions going on in the cytoplasm and organelles, where often byproducts are destructive free radicals, acids, bases, etc. If DNA is damaged, it can be repaired but lots of damage and mistakes in repair lead to mutation, which is permanent, and that can destory the genes so the cell cannot function normally.

Hope that helps.

Answer 3

Let me simplify that last answer for you....
nuclear pores are advantageous for RNA because that is how they get out of the nucleus to go and be translated in the cytoplasm of the cell.
