Open Reading Frames * (ORFs) are regions with no stop codons. All genes reside in long open reading frames * Note that stop codons in other reading frames have no effect on the gene. * Can be searched in the genome sequence. Valid only for prokaryotes and lower eukaryotes. Protein Sequencing vs. DNA sequencing * We compare protein sequences‚ not DNA‚ because protein is more conserved in evolution than DNA * The organism’s survival depends on the protein being

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Egg Lab Report Introduction: An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in
