If you think the 2 options are "exactly the same as life on earth" or
"not based on carbon compounds" you are missing a huge middle ground.

Starting right from the basics, amino acids come in right and left
handed versions. Life on earth uses one, but nobody thinks the other
would not work just as well.

We only use 4 bases in our DNA, but there have been recent experiments
that inserted another 2 in a test organism, so that is another option
for life elsewhere.

Here we use base triplets to encode for each amino acid in a protein,
with quite a bit of redundancy in the coding. There is probably some
chemistry backing the basics of the coding, but using 4-base sequences
is probably possible, just less efficient.

So, the basic chemical makeup will be similar, but the details will
probably vary quite a lot.

As to "needs and requirements", on a simple level, yes they will
be the same (or very similar). Organisms will require food, energy
(maybe from food, maybe from light), shelter. Or did you have something
else in mind?
