Kingdom. This is because biologists recognized the differences between eukaryotes and prokaryotes, which were once part of the five kingdoms alongside plantar, animalia and fungi. However having them part of the Kingdom category proved to be difficult. Thus the inclusion of three domains occurred - bacteria, archaea and eukarya. The domain bacteria consists of commonly known prokaryotes, whereas the domain archaea too contains prokaryotes but the can inhabit a range of environments. The domain eukarya consists
Eukaryotes and prokaryotes There are only two types of cell in the world, these are eukaryotic and prokaryotic cells. They are both similar and different in many ways, for example prokaryotes are only a few micrometres in size whereas eukaryotes are between 5-100 micrometres and nearly 10,000 times the volume of that of a prokaryote. A chemical similarity between the two is that they both either contain or use proteins, carbohydrates, lipids and nucleic acids to store or create energy. Both eukaryotes
organelles within eukaryotes cells; explain evolutionary advantages of intracellular compartmentalization. Living cells are the functional biological building blocks of animals. They come together to form complex organic tissues, organs, and whole bodies, as well as some of these organisms themselves existing in a unicellular form. Cells vary in size and dimension, with Eukaryotes ranging from 1x10-3m to 1x10-4m in length, whilst the smaller and less structurally complex Prokaryotes exist between
The Serial Endosymbiotic Theory (SET) was a hypothesized process by which prokaryotes give rise to the first eukaryotic (an organism which contains a nucleus and organelles enclosed within a membrane ). Was pioneered in the 1960’s by the seminal work of Lynn Margulis. This theory attempts to explain the origins of eukaryotic cell organelles, specifically the mitochondria (providing the cells ATP (used for the cells metabolism) supply used by the cell as chemical energy ). With the theory suggesting
not have (Reece et al 2009). First, the Eukaryotes which are in the human, beside the animal, or in the plant in general, and they are intricacy cells (Reece et al 2009). Furthermore, the Prokaryotes which exists in the bacteria and archaea, are simple cells (Minorsky 2009). So there is a simple kind in cells and another kind that would be a complex one. According to Silverstein (2002), he clarified that "The term prokaryote means before nucleus; eukaryote means true nucleus"(n.p.). The author Silverstein
classed as either multicellular or unicellular. Multicellular organisms includes plants and animals and unicellular including bacteria and single cell organisms. There are two types of living cells, prokaryotes and eukaryotes. Prokaryotes where the first form of life on Earth. In comparison to eukaryotes they are a lot simpler in structure and lack membrane bound organelles such as a nucleus. They can typically be found in organisms such as bacteria and archaea. A prokaryotic cell will have a flagellum
Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya. The Domain Bacteria Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms (Reece, et
An organism is heterozygous at two gene loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. After mitosis the parent cell's genome is dividedninto two daughter cells. In most eukaryotes, the nuclear envelope that separates the DNA from the cytoplasm disassembles. The chromosomes align themselves in a line spanning the cell. As the cell elongates, corresponding sister chromosomes are pulled toward opposite ends. A new nuclear

Sequence Information of Proteins Just as members in the same family often resemble each other, similarly structured molecules are often grouped in the same category. There are several methods of comparing amino acid sequencing and determining how closely they are related. A simple example is the sequence-comparison method. Sequence databases are searched for a specific amino acid sequence of unknown characteristics. A set of molecules that are similar in structure can give insight into the properties
