Summary Writing – The CBSE Way by Admin on October 13‚ 2012 in English Man created remote to avoid going over to the TV every time to switch a channel. Huge articles were always there‚ some too huge that if we had such an article in exam; we would end up reading it all the three hours. To tackle this‚ man created short notes and summaries. Why re-read huge articles again and again when you can get the gist of it in just 1/3 rd of its length? Sound’s better no? Summaries can be of variable length

Yuri Anthony D. Sucgang BMLS-IA Electrophoresis Machine Gel Electrophoresis Apparatus(Aragose Gel) Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson‚ we’ll review how agarose gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment.
