| ARTICLES RELATED TO eukaryote | | | |  eukaryote: Encyclopedia II - Mitochondrial genetics - RelevanceBecause they provide 36 molecules of ATP per glucose molecule in contrast to the 2 ATP molecules produced by glycolysis, mitochondria are essential to all higher organisms for sustaining life. This is why slight problems with any one of the numerous enzymes used by the mitochondria can be devastating to the cell, and in turn, to the organism. Also, mitochondria specialize depending on what cells they exist in, and they perform specific functions at different stages in ...

| | | | | eukaryote: Encyclopedia II - Mating of yeast - The importance of a and α mating types The key differences between the a and α mating types are:
a type cells produce the a pheromone and the α receptor
α type cells produc the α pheromone and the a receptor
As the pheromones are an important signal in inducing the mating process it is important the a and α genes must also act with each other (in the diploid cell) to prevent the production of any p ...

| | | | | eukaryote: Encyclopedia II - Mating of yeast - The life cycle of yeast There are two forms in which yeast cells can survive and grow, haploid and diploid. The haploid cells undergo a simple life cycle of mitosis and growth, and under conditions of high stress will generally simply die. The diploid cells similarly undergo a simple lifecycle of mitosis and growth, but under conditions of stress can undergo sporulation, entering meiosis and producing a variety of haploid spores (showing genetic variation), ...

| | | | | eukaryote: Encyclopedia II - Mitochondrial genetics - Mitochondrial Replication Repair Transcription and Translation Mitochondrial replication is controlled by chromosomes in the nucleus and is specifically suited to make as many mitochondria as that particular cell needs at the time. Mitochondrial polymerase is used in the copying of mtDNA during replication. Because the two (heavy and light) strands on the circular mtDNA molecule have different origins of replication, it replicates in a D-loop (displacement) configuration. One strand begins to replicate first, displacing the other strand. This continues until replication reaches the origin of replication ...

| | | | | eukaryote: Encyclopedia II - Geyser - Geysers on Triton One of the great surprises of the Voyager 2 flyby of Neptune in 1989 was the discovery of geysers on its moon, Triton. Astronomers noticed dark plumes rising to some 8 km above the surface, and depositing material up to 150 km downstream.
All the geysers observed were located between 40° and 60°S, the part of Triton's surface close to the subsolar point. This indicates that solar heating, although very weak at Triton's great distance from the Sun, probably plays a crucial role. It is thought that the surface of Triton prob ...

Genetics - Classical genetics.
Main articles: Classical genetics, Mendelian inheritance
Classical genetics consists of the techniques and methodologies of genetics that predate the advent of molecular biology. After the discovery of the genetic code and such tools of cloning as restriction enzymes, the avenues of investigation open to geneticists were greatly broadened. Some classical genetic ideas have been supplanted with the mechanistic understanding brought by molec ...

| | | | | | | | | | | eukaryote: Encyclopedia II - Magnetotactic bacteria - Magnetosomes The biomineralisation of the magnetite is brought about by the regulating mechanisms of the concentration of iron, by the nucleation of crystal, of the potential redox and of the pH. The compartimentalisation in magnetosomes permits the biochemical control of such processes. After the sequencing of the genome of certain species of MTB, a comparative analysis of the proteins involved in the formation of BMP became possible. In this way similarities in the sequence between members of the ubiquitaria family CDF (Cation Diffusion Facilitator) an ...

| | | | | | eukaryote: Encyclopedia II - Geyser - Misnamed geysers In a number of places where there is geothermal activity wells have been drilled and fitted with impermeable casements that allow them to erupt like geysers. Though these so-called artificial geysers, technically known as erupting geothermal wells, are not true geysers, they can be quite spectacular. Little Old Faithful Geyser, in Calistoga, California, is an erupting geothermal well.
Sometimes drilled cold-water wells erupt in a geyser-like manner due to the build-up of pressure from dissolved carbon dioxide in the wate ...

| | | | | eukaryote: Encyclopedia II - Geyser - Numbers and distribution Geysers are quite rare, requiring a combination of water, heat, and fortuitous plumbing. The combination exists in few places on Earth. The five largest geyser fields in the world are (Glennon, J.A. and Pfaff R.M. 2003; Bryan 1995):
1. Yellowstone National Park, Wyoming, United States
2. Dolina Geiserov, Kamchatka Peninsula, Russia
3. El Tatio, Chile, South America
4. Taupo Volcanic Zone, North Isl ...

| | | | | eukaryote: Encyclopedia II - Magnetotactic bacteria - Applications The unique characteristics of BMP permit practical uses in a variety of fields, improving upon older techniques and introducing completely new ones. Common advantages across these areas include:
being surrounded by a double layer helps form compounds that are easily dispersed in watery solutions, as opposed to articles that are obtained artificially [4]
their size renders them superparamagnetic, that is, they quickly follow changes in the external magnetic field without any remnants of the preceding polarity [10].
