Chondrichthyes were my motivation to get involved and stick with Marine Biology no matter the challenges. Growing up I found comfort in sharks. Due to media and lack of understanding sharks were viewed only as malevolent killing machines. I thought this false‚ constraining label was unjust and unwarranted. Just as sharks had a constraining label I was stereotyped to be at best average when it came to academics. I had a minor learning disability that made reading and writing a major obstacle. After

and synthetic biology are two techniques that go hand in hand but differ ever so slightly. It is this slight divergence that makes a world of a difference. Gene editing is defined as the process of editing an organism’s DNA by altering‚ removing or adding nucleotides to the genome. Whereas synthetic biology is defined as a combination of molecular biology and systems biology with engineering principles to design biological systems and bio-factories‚ or the use of molecular biology tools and techniques

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors

Aim: The aim of this experiment is to investigate the process of Electrophoresis and successfully analyse DNA fragments. Hypothesis: That the experiment will show the visual representation of DNA proteins‚ and that the shorter the band the further is will travel. Background: Restriction enzymes are DNA-cutting enzymes found in bacteria‚ which cut DNA into smaller fragments. A restriction enzyme recognizes and cuts DNA only at a particular sequence of nucleotides‚ known as restriction sites

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

Biology revision test ch.6 2 mid-term exam Marks: /110 1. The following diagram shows two similar models simulating a region of the mammalian alimentary canal. The water in the test tubes surrounding the dialysis tubings was tested with standard food test reagents at the beginning of the experiment and again after one hour. The results showed that neither starch nor reducing sugar was present in the water surrounding tubes A and B at the beginning of the experiment. (7

What is passive transport? Passive transport is the movement of substances across the cell membrane without the use of energy by the cell. During passive transport‚ substances move down their concentration gradient‚ hence no energy is required. Passive transports can happen through three different channels‚ namely 1. lipid bilayer 2. pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low
