Archaea

Respiration and Photosynthesis Respiration and photosynthesis are reactions that take place in the environment which complement each other, in the other case can be seen as a same reaction but happening in reverse of each other (Tang, 2005). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Respiration to take place requires glucose and oxygen to yield carbon dioxide and water. Since the product of…

The [Just say, "fuck animals"](https://www.reddit.com/r/vegan/comments/5umewu/just_say_fuck_animals/) thread compeled me to reflect a bit and advance this post inquiry in an attempt to dissect the logical foundations of the vegan principle. I can see how vegans feel that there's a lot of hypocrisy regarding beliefs and attitudes that relate to animal well-being. But it seems unfair and shortsighted to assume that everyone who eats meat basically doesn't care about animals, imo. I'm omni, and I…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

Form I Rubisco. This structure is similar to the structure of the basic dimer of the Form I Rubisco despite some differences in catalytic properties.16,17 Form III Rubisco is the dimers of large subunits in either an L2 or (L2)5 and is found only in archaea. Form IV Rubisco (Rubisco-like Protein) is a simple dimer of large subunits (L2) that do not use CO2 as a major carbon source.18,19…

The RNA worlds together with the DNA world are known to have numerous differences as well as similarities with the cell nature as well as the varied virus character demands pointing to the viruses coming first. To a degree, the theories that designate this phenomenon have contended on the dissimilar nature of viruses, as a crucial factor that illustrates the viruses coming first (Woese, 1987). In the biosphere of microbes, whereas viruses are regarded as minuscule in size, the Pithovirus is…

viewed 19th March 2016, Cells can be classified into two major groups- Prokaryotic and Eukaryotic cells. Prokaryotes are organisms that do not contain a cell nucleus and have no membrane bound organelles. Prokaryotes can be divided into two domains, Archaea and Bacteria. However organisms, whose cells are organized into complex structures by a nucleus, contain internal membranes and a cytoskeleton are known to be Eukaryotes. Similarly plant and animal cells can be classified into eukaryotic…

Cell division is a complex biological method in which a parent cell divides into two or more daughter cells, depending on whether or not that division is mitosis or meiosis. For simple one-cell organisms, like amoebas, archaea and protozoa, single cell division, mitosis, is akin to reproduction. For multicellular organisms, meiosis produces four haploid daughter cells by undertaking a single round of DNA replication, shadowed by two more cellular divisions. In all, the principal purpose of cell…

Silver nanoparticles have unique antimicrobial properties. They have a variety of applications: diagnostics, wound healing, pharmaceuticals, etc. These nanoparticles destroy bacterial cells walls and interrupt membrane integrity by their electrostatic attraction to the negatively charged bacterial cell walls [10]. Metal nanoparticles are usually synthesized by chemical techniques which is costly and highly toxic. Currently, there is a growing demand for alternative methods that would limit the…

The aim of the data analysis exercise was to determine genetic relationships between the HSP70 amino acid chains of fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes,…

Genome editing is a fairly new area of science as well as it theoretical benefits it also has it drawbacks, according to (incite reference). It 's is where genes are cut, deleted or inserted in the DNA which in turn changed the sequence of DNA of an organism or cell Various engineered nucleases can be used to carry out the genome editing, this include TALENs (Transcription activator interspaced nuclease), ZFNs (Zinc-finger nuclease) and CRISPR-Cas9 (Clustered regularly interspaced palindromic…
