Archaebacteria and Strep

ACTSCI-TGLQLG

Archaebacteria are also known as extremophiles. They are simple single celled organisms that make their homes in places like chimneys, mud springs, and geysers. Some species may be as much as 4.2 billion years old. More modern bacteria, such as streptococcus, have antibiotic resistance genes that can be passed from organism to organism in a simple variation of sexual reproduction.
