Hace 14 horas · The eukaryotes (/ j uː ˈ k ær i oʊ t s,-ə t s / yoo-KARR-ee-ohts, -əts) constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus.All animals, plants, fungi, and many unicellular organisms are eukaryotes. They constitute a major group of life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea.
Hace 2 días · A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
17 de may. de 2019 · Definition. 00:00. …. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP). Mitochondria contain their own small ...
Hace 2 días · Definition. A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
Hace 2 días · In this animation, you can watch a diploid (2N) animal cell go through two rounds of meiotic divisions in order to form four haploid (N) gametes. Note that when meiosis begins, each chromosome has already been replicated and exists as two sister chromatids held together at the centromere .
