Proteins are chains of amino acids, which are joined like letters in a sentence (or book). There are about 20 amino acids, they can be joined in any order, and there is no hard limit to the size of the chain.
There are an infinite number of prime numbers.
I am sure that there are 25 prime numbers exist in mathematics
Theoretically, infinity has an infinite number of factors.
A thing does not have to be finite for it to exist. Furthermore, it is possible that time is not infinite but when the Big Crunch happens, space-time will cease to exist.
an infinite number of fractions exist in any portion of anything.

Infinity is the worlds strangest number as it is not - in many respects - a number at all. It is a concept that cannot exist, as far as we know.it is infinite XD
Such a list cannot exist, because there are an infinite number of such fractions.
In general, you cannot. An infinite number divided by any non-zero number is still infinite. An infinite number divided by another infinite number may or may not be infinite.
There are virtually an infinite amount of different skin colours that exist since the possibilities of shades are infinite.
There is no lowest mixed number since, given any mixed number, it is always possible to find a lower one.
There isn't one. Numbers don't stop. There doesn't exist a number so large that one can't be added to it.
