WebEukaryotic chromosomes consist of DNA tightly wound around clusters of histone proteins. In general, eukaryotic cells contain a lot more genetic material than prokaryotic cells. For example, each human cell has around … WebBy definition, eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal cells. In addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others.

WebSep 23, 2024 · In eukaryotes, the initiating amino acid is methionine, not N-formylmethionine as in prokaryotes. As in prokaryotes, a special initiator tRNA is required for initiation and is distinct from the tRNA that recognizes and binds to codons for methionine at internal positions in the mRNA. WebRather, Eukaryotic genes present in bacterial and archaeal organisms are hypothesized to be from horizontal transfer from an early ancestor of modern eukaryotes. This putative ancestor possessed crucial "starter" genes that enabled increased cellular complexity. This common ancestor, or a relative, eventually led to the evolution of eukaryotes.
