    As seen on many crime shows and in real-life crime scenes, it is necessary to be able to identify DNA. Most of the time, this is done using a technique known as gel electrophoresis. Gel electrophoresis is a method used to separate the macromolecules that make up nucleic acids, such as DNA and RNA, along with proteins. Gel electrophoresis is significant because it has given scientists insight on what cells cause certain diseases and has led to advancements in DNA and fingerprint identification. My

    For Learning Centre use only Activity 1: Simulating Dialysis (Simple Diffusion) Lab Report Review Sheet Results 1. 2. Describe two Variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: A. The size of the molecule. The larger molecule will diffuse more slowly than the smaller molecule. B. The nature of plasma membrane. If the membrane is composed of lipid portion., only lipid soluble molecules can pass through while water molecules

    Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

    Biotechnology is the application of scientific techniques and exploitation of biological processes used to improve and modify animals, plants and microorganisms to enhance their value through genetic manipulation. Over time, advances in the field of molecular biology has allowed scientists to take a particular gene from any organism, including, bacteria, viruses, plants or animals, and introduce those genes into another organism. An organism transformed using genetic engineering techniques is known as

    BIOSCI 751 – Molecular Plant Microbe Interaction Evolution of plant pathogens Introduction: Plant and microbial interactions are present right from the establishment of land plants. The plants have co-evolved with the microbes since then (Gehrig et al., 1996). A microbial interaction with the plant can have both positive and negative effects on the plant. Due to this, it has gained high agronomic importance in today’s plant science research (Stacey et al., 1996). Plant Immune System: A pathogen

    Proteins are primarily considered to have one primary function to serve its role in an organism, however studies have observed to have multiple functioning proteins known as moonlighting proteins (Khan et al. 2014). Moonlighting proteins along with primary functions, have secondary functions that are not related to the primary function and does not correlate to the primary or other functions (Khan et al. 2014). The multifunctional proteins play essential roles in carrying out biochemical functions

    An excessive amount of asphaltene deposition may result in a severe formation damage and sometimes blocking the flow path as seen in Figure 6c. Therefore, the injected solvent cannot further diffuse deep into the matrix (due severe to asphaltene deposition) and eventually causes injectivity problem. In this study, C5 injection resulted in the high amount of asphaltene deposition in porous media (11.4 % per Figure 7) and it could block the main flow path, the fracture (as seen in Figure 6c). The pressure
