Marissa Arias Senior Rhetoric Graf-8 April 14‚ 2014 Gel II Manicure Many women and even some men love to get their nails done‚ but hate how much time it takes to dry and on top of that they are extremely easy to ruin and chip. There is a new type of manicure trending know as Shellac‚ Gel nails‚ or No chip. According to my cosmetology instructor Samantha Rudman‚ this process takes about 35 to 40 minutes but dries in seconds. Many individuals would love to know this process even the men that

Agarose Gel Electophoresis of DNA Topoisomers Introduction DNA can exist as different isomers that change the confirmation of the DNA’s structure. DNA can be in a linear confirmation this is a relaxed confirmation as the DNA can rotate about its axis unconstrained. It can also exist as a nicked circle this is also a relaxed confirmation as the DNA strands can again rotate freely with respect to one another. Covalently closed circular DNA or cccDNA exists as a supercoil this is because the covalent

The container in which the gel is stored has a negative and positive side; whichever side the DNA molecules go to means the DNA is charged the opposite way. (Ware‚ Lunte‚ Gardiner)For example if a DNA molecule

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

SDS-PAGE Laboratory Summary Electrophoresis is a technique where molecules are separated according to their physical properties such as size‚ charge‚ and/or shape. Charged proteins are commonly separated in this matter using PAGE (polyacrylamide gel electrophoresis) to identify individual proteins present in samples. In this lab‚ SDS-PAGE was used. SDS-PAGE separates charged proteins primarily by size because the ionic detergent sodium dodecyl sulfate (SDS) with 2-mercaptoethanol disassociates
