The Archaea are best known for the extremophiles, those cells that "love" extreme environments, such as very high temperature, high pressure, extreme pH, high metal ion concentration, and high salt. Members of the Archaea resemble Bacteria morphologically, occurring with shapes such as spheres, rods, and spirals. However, genome sequencing of a number of archaean genomes revealed some key differences. Which of the following is an INCORRECT statement about Archaea?
As in eukaryotes, there are introns in protein-coding genes and tRNA genes of Archaea.
