Chronological lifespan of S. cerevisiae mutants lacking telomere capping protein Cdc13 and Exo1 Lay summary For over 25 years, yeast has been used as a model to understand cellular processes such as how; DNA is repaired and produced, also for understanding different aspects of the cell lifecycle and principle molecular processes in eukaryotes (the same type of cells that make up humans, animals and plants). Because yeast can be easily grown until it dies in a relatively short time, it is an…

There are certain animals, plants, fungi, bacteria, and viruses that tolerate and actually thrive in extreme conditions. These organisms are called extremophiles. The word extremophile breaks up into “extreme” and the suffix “phile” literally means “one who loves.” These organisms flourish in the uninhabitable places that vary from extremely high and low temperatures, high pressures, high salinity, the absence of water, and extreme amounts of radiation just to name a few. Many of these…

Magnesium Sulphate Paste Magnesium sulfate, also known as Epsom salt, is a common household item that has numerous uses. Some people use it for therapeutic purposes, especially when used in hydrotherapy, bath soaks, and other formulas. One form of therapeutic product commonly used is magnesium sulphate paste, which you can make at home for personal use. This paste can be used like a skin ointment to treat common conditions. Learn more about the benefits of magnesium sulphate and how to make your…

far 13 Aquaporins have been discovered (AQP0-AQP12) some of the Aquaporins only transport water molecules, such as AQP1, AQP2, AQP4, AQP5 and AQP8. Aquaporins that transport water and other solutes are called aquaglyceroporins, these can transport glycerol, CO2, ammonia and urea across the membrane, depending on their pore size. The aquaglyceroporins consist of AQP3, AQP7 and AQP9. AQP6 has been classified to function as an intracellular chloride channel. All of these Aquaporins can be found in…

Restriction Mapping of Plasmid DNA Preparing 5 Eppendorf Tubes All tubes contain 1 μL of the plasmid DNA, and 2 μL of 10X buffer #2. Tube 1 is the control so there is no enzyme added only 17 μL DI water. For tube 2 the DNA is mixed with 0.5 μL of BamHI and 16.5 μL of DI water, to see total number of base pairs from the linear DNA. In tube 3 DNA is digested with 2 restriction enzymes, which can give the relative distance between the two enzymes. To be more specific, 0.5 μL of Bam HI and EcoRI…

Sixty genera of coral have a symbiotic relationship with the algae zooxanthellae. Only some deep water and cold water corals can survive without them. This symbiotic relationship benefits both organisms, the zooxanthellae provides the coral with glycerol, glucose and alanine. The coral provides the zooxanthellae with nitrogen and protection against predators. The degree to which the organisms depend on one another varies between species. (Rupert and Barnes, 1994). Coral bleaching occurs when the…

there was an accident the vital organs will be saved such as the kidneys or heart. Lipids help aquatic animals such as sea lions, whales, penguins and all kind of fishes to float on water, it helps with the buoyancy. Many lipids are formed when a glycerol molecule combines with compounds called fatty acids. If each carbon atom in a lipid’s fatty acid chain is joined by another carbon atom through a single bond then the lipid is said to be saturated. Saturated means that the fatty acids contain…

IV. METHODOLOGY SAPONIFICATION VALUE Saponification is a method used in treating a neutral fat with alkali, breaking it down to glycerol and fatty acids. The saponification value or saponification number is the amount of alkali needed to saponify the given quantity of fat or oil, expressed as mg potassium hydroxide to saponify 1 g of the sample. In this experiment, the researchers used chemicals such as ethanol, hydrochloric acid (HCl), potassium hydroxide (KOH) and phenolphthalein indicator.…

nicotine delivery devices (ENDS) consist of a battery, a reservoir of liquid, and an atomizer that, when heated by the battery’s energy, produces an aerosol that is inhaled by the user. The liquid in the reservoir contains nicotine, propylene glycol or glycerol, and some kind of flavoring (Pruitt 2016). E-cigarettes were introduced to the United States in the year 2007. The market for e-cigarettes has been doubling annually since then (Cantrell 2013). The alleged reason for the invention of the…

membrane looks like. All membranes have the same basic structure made up from phospholipids (fats). The membrane is made up of a phospholipid bilayer; consisting of a polar phosphate head and two fatty acid tails. The head is made from an alcohol and glycerol group and has a non-polar fatty acid tail made up from two strings of hydrogen and carbon atoms. The head cannot pass through the tails giving the bilayer stability. Despite the stability of the bilayer, the phospholipid…
