Methanococcus voltae is a type of archaeon, which means it belongs to a group of microorganisms distinct from bacteria and eukaryotes. Archaea, including Methanococcus voltae, do not have a membrane-bound nucleus; instead, their genetic material is located in a region called the nucleoid, which is not enclosed by a membrane. Therefore, Methanococcus voltae does not possess a nucleus with a membrane.
it is a eukaryote
No, Methanococcus voltae does not reproduce sexually. It is a single-celled microorganism that reproduces through a process called binary fission, where the cell divides into two identical daughter cells.
Methanococcus jammaschii is one example of the Archaea kingdom. More names /examples can be found at the Related Link below. Archaea, unlike bacteria, does not have peptidoglycan (also known as murein), which is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of only bacteria and helps form the cell wall. Archaea is more related to eukaryotes than bacteria, which is why the name changed for Archaeabacteria to just Archaea. They live in extreme conditions, but can be found in other places, such as 30% of marine microbes. Archaea does not cause infections to humans. One example of Archaea is Methanococcus jammaschii, which is one of the first to make the above classification clear.
