How are domains Archaea and Bacteria similar?
Both bacteria and archaea have cell membranes and they both contain a hydrophobic portion. In the case of bacteria, it is a fatty acid; in the case of archaea, it is a hydrocarbon (phytanyl). Both bacteria and archaea have a cell wall that protects them.
Why are Bacteria and Archaea in the same domain?
Scientists thought that archaea and bacteria were the same because they both are bacteria.
Which are more closely related to complex organisms bacteria or archaea explain?
a) How are bacteria and archaea similar? (1 point)Bacteria and archaea are similar because both are organisms consisting of a single cell that lacksa nucleus or organelles. (2 points)Archaea are more closely related because on the basis of cladistics analysis they match better than bacteria.
Why are archaea more closely related to eukaryotes than bacteria?
Despite this visual similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely-related to those of eukaryotes, notably the enzymes involved in transcription and translation. Archaea exhibit a great variety of chemical reactions in their metabolism and use many sources of energy.
What do the domains Bacteria and Archaea have in common quizlet?
Together both domains form a paraphyletic group. Bacteria, archaea and Eukarya all have the same common ancestor. vital in nutrient recycling, incredibly small organisms, but important to larger, multicellular organisms. Cell walls in gram-negative bacteria have some peptidoglycan and an outer membrane.
Recent evidence indicates that Archaea and Eukarya are more closely related to each other than either is to Bacteria. According to the evidence, all three domains of life share a common ancestor that probably existed more than 3 billion years ago (bya). Two lines of descent emerged from this ancestor.
How are Archaea and eukaryotes similar?
Both can carry out asexual reproduction. Translation and transcription that occurs in Archaea is similar to that that occurs in Eukaryota (the one in bacteria is unique). DNA replication in Archaea is similar to that in Eukarya.
Why are Archaea more closely related to eukaryotes than bacteria?
What are some similarities and differences between bacteria Archaea and eukaryotes?
Both Bacteria and Archaea are prokaryotes, single-celled microorganisms with no nuclei, and Eukarya includes us and all other animals, plants, fungi, and single-celled protists – all organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell.
