In some ciliate protozoa,the codons UAA and UAG encode glutamate,rather than acting as STOP codons.How does this compare to other species?
A)This is unusual - almost all species share the same "universal" genetic code.
B)This is typical - every species has its own unique genetic code.
C)This is not unusual - while most species have a similar genetic code,there are often variations for some of the amino acids.

This is unusual because the genetic code is nearly universal across all species, with only a few exceptions where specific codons might encode different amino acids or functions, such as the case mentioned.
