A 1977 scientist found the S-2L virus which infects cyanobacteria, This virus does not encode adenine, This instead codes for diaminopurine, shortened to Z. This derivative will make 3 hydrogen bonds instead of adenine's 2. This is incredibly interesting as we can see the genetic mutations occurring in this virus that allows it to use a whole entire new coding language. perhaps eventually even humans will use this coding language as well!!

It’s crazy how mutations can drastically change the way things function on a cellular level. The implications of this virus, which codes for "diaminopurine" rather than adenine, can better shape humanity’s understanding of how genetic mutations can impact how viruses and larger lifeforms function.
