Why are trapezoids outside the parallelogram?
Trapezoids are not considered parallelograms because parallelograms have 2 pairs of parallel sides, whereas trapezoids have only one. Some definitions of trapezoid say "at least one pair of parallel sides" in which case, some trapezoids would be parallelograms (the ones that have 2 pairs of parallel sides), but most textbooks in the US now define trapezoids as "exactly one pair of parallel sides."
Does a square have two pairs of perpendicular sides?
A square has 4 corners where a pair of sides meet at right angles, so there are 4 pairs of perpendicular sides. Now, consider this: I have 50 dollars, and you ask me if I have two dollars. I say "Yes.", because I do have 2 dollars, plus quite a bit more. If you agree with this logic, you could answer your question with a "yes". However, if the question said, "Does a square have exactly two pairs of perpendicular sides", you would have to say, "No, it has exactly four!"
What has 2 pairs of parallel sides and no right angle?
Every non-rectangular parallelogram has. (It's not correct to say that a parallelogram has, because rectangles and squares are parallelograms too.)

What does it mean to say that there is a proofreading functioning DNA replication?
It basically means that because when a DNA double helix 'unzips' and free-floating nucleotides go to pair with the base pairs, if their was a mistake, it will be fixed. For example- say this is what the DNA 'read' originally A - T A - T C - G G - C T - A G - A The last pair is incorrect, because Guanine and Adenine don't pair up, well, when it unzips and they're separated, C will bond with G, and T will bond with A, that way the pairs are now correct and that the pair isn't re-replicated.
