Chromatin and Chromosomes - Packed inside the nucleus of every human cell is nearly 6 feet of DNA, which is divided into 46 individual molecules, one for each chromosome and each about 1.5 inches long. It is also attached to a network of tubules and sacs, called the endoplasmic reticulum, where protein synthesis occurs, and is usually studded with ribosomes (see Figure 1)

The CANDU and RBMK types have pressure tubes (rather than a pressure vessel enclosing the reactor core) and can be refuelled under load by disconnecting individual pressure tubes. The development of nuclear power based on Pb-Bi cooled fast neutron reactors is likely to be limited to a total of 50-100 GWe, basically for small reactors in remote places

A contractile ring, comprised of non-muscle myosin II and actin filaments, assembles equatorially (in the middle of the cell) at the cell cortex (adjacent to the cell membrane). In plant cells, a dividing structure known as the cell plate forms across the centre of the cytoplasm and a new cell wall forms between the two daughter cells

PRICKLY PEAR CACTUSPrickly pear cacti (genus Opuntia, many species) are North American desert succulents that have flat, fleshy, leaf-shaped pads and large spines (modified leaves) growing from tubercles (small bumps on the pads). PLEISTOCENEThe Pleistocene was an epoch of geologic time that lasted from 1.8 million to 11,000 years ago; it was a period of widespread glaciation and large Ice Age animals (caled Pleistocene Megafauna)

Amongst the ways in which plant cells ablude from animal cells is the fact that they contain a fluid filled vacuole and have a hard outer wall; this is made of cellulose. As both animals and plants are eukaryotic organisms they also share many features within their cells, some of the organelles that they share include the nucleus, which contains the chromosomes and DNA; the ATP producing mitochondria; the protein processing golgi bodies and endoplasmic reticulum, and the 'liquid soup' cytoplasm
Plant Cell
http://biology.about.com/od/cellbiology/ss/plant-cell.htm Competition: low
In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. While animal cells come in various sizes and tend to have irregular shapes, plant cells are more similar in size and are typically rectangular or cube shaped

By comparison, the wastes from coal burning plants that end up in the ground will eventually cause several thousand deaths from generating the same amount of electricity. To date, the largest number of noticeable deaths from coal burning was in an air pollution incident (London, 1952) where there were 3500 extra deaths in one week

From the reactor, the water in the primary system flows through a steam generator where heat is transferred to water in the secondary system, boiling it to steam. Ron Johnson, a member of the Prairie Island Indian Community tribal council, spoke about the partnership among his community, Xcel Energy and the city of Red Wing regarding efforts to persuade the federal government to live up to its promise to remove used nuclear fuel from the Prairie Island plant site and store it elsewhere

McBride at Oak Ridge National Laboratory (ORNL) and his colleagues looked at the uranium and thorium content of fly ash from coal-fired power plants in Tennessee and Alabama. Anyone with knowledge of naturally occuring radioactive materials is aware that coal fired plants spew more radioactive material than nuclear plants, in addition to all of the other things that coal plants emit

A plant cell is bounded by a cell wall and the living portion of the cell is within the walls and is divided into two portions: the nucleus, or central control center; and the cytoplasm, a fluid in which membrane bound organelles are found. The proteins synthesized on ribosomes bound to granular endoplasmic reticulum are transferred from the lumen (open space inside endoplasmic reticulum) to the golgi apparatus for secretion outside the cell or distribution to other organelles

In a LWR, the entire reactor core is a single large pressure vessel containing the light water, which acts as moderator and coolant, and the fuel arranged in a series of long bundles running the length of the core. Such language gives the impression that events will unfold in an orderly and predictable manner, and generating station personnel only need to refer to their training scenarios to respond to any foreseeable emergency

In higher plants, the diploid generation, the members of which are known as sporophytes due to their ability to produce spores, is usually dominant and more recognizable than the haploid gametophyte generation. By the Carboniferous Period, about 355 million years ago, most of the Earth was covered by forests of primitive vascular plants, such as lycopods (scale trees) and gymnosperms (pine trees, ginkgos)

not dividing, the chromosomes are organized into long entangled structures called chromatin and not into individual chromosomes as we typically think of them.The Nucleolus:The nucleus also contains the nucleolus which helps to synthesize ribosomes. The envelope helps to maintain the shape of the nucleus and assists in regulating the flow of molecules into and out of the nucleus through nuclear pores

Autophagy or the process in which the elements of a cell are degraded also has a lot to do with the vacuole, because it needs to ensure the perfect balance between the biogenesis and the turnover of substances in the structure of the cell. They help to support plants while not restraining growth due to their lack of secondary walls and the absence of a hardening agent in their primary walls

Many nuclear pores are inserted in the nuclear envelope, which facilitate and regulate the exchange of materials (proteins such as transcription factors, and RNA) between the nucleus and the cytoplasm.Each of the two membranes is composed of a lipid bilayer. The outer membrane is continuous with the rough endoplasmic reticulum while the inner nuclear membrane is the primary residence of several inner nuclear membrane proteins

Franz Meyen was a strong opponent of this view, having already described cells multiplying by division and believing that many cells would have no nuclei.

By controlling the traffic of molecules between the nucleus and cytoplasm, the nuclear pore complex plays a fundamental role in the physiology of all eukaryotic cells. Transcription factors, for example, are functional only when they are present in the nucleus, so regulation of their import to the nucleus is a novel means of controlling gene expression
Nuclear Envelope

For example, molecules of: 5,000 MW are freely diffusable 17,000 MW-- take 2 min to establish equilibrium 44,000 MW--take 30 min to establish equilibrium 60,000 MW--cannot move in by diffusion This concept is important because it means that mature ribosomes (with both subunits joined) cannot reenter the nucleus. These intermediate filaments are polymers of lamin, ranging from 60-75 kD A-type lamins are inside, next to nucleoplasm; B-type lamins are near the nuclear membrane (inner)
