>>10

Simplest proteins are not less of 100 aminoacids long. For example insulin one of the smallest protein known is 110 aa (human version).

So, to code insulin u need (110 * 3) + 3 dna symbols (called nucleotides).

Why *3? Because there are 20 (or 22... including the 2 not much used) aminoacids thar are used in living beings to make proteins.
The cheapest way to code for 20 things with an alphabet of 4 symbols is by using words of size 3.

Why +3? Oh, not so important, it is just the stop codon that marks the "protein coding section" end.

Virus typically have genomes ranging from 10^3 to 10^4 bp. "Simple" life forms like bacteria have genomes on the order of 10^7 bp. Human genome is around 4 * 10^9 bp long.

The funny thing is that there are plants and animals (eg. puffer fish) with bigger genomes than the human one.
