Ribosome

for identification. If its cell wall is thin and stains red, it is referred to as gram negative. Under the cell wall, the bacterium also has a plasma membrane made up of a phospholipid bilayer with proteins inserted inside. Within its cytoplasm, ribosomes for protein synthesis and a single DNA strand are…

Clostridium tetani is a rod shaped microorganism’s bacteria in charge of the frequently lethal infection tetanus he word tetanus originates from the Greek word tetanus, which anticipates the meaning to stretch. Tetanus is described by unbending nature and sudden contractions of skeletal muscle and infection within the integumentary system, skin (Tortora, et al., 2016). Bacterial cells, similar to plant cells, are surrounded by a cell wall. However, bacterial cell walls are comprised of…

antimicrobial activity is focused on the inhibition bacterial protein synthesis. As macrolides have 1,2, and 3 ribosomal binding, they are able to achieve this inhibition through reversible bindings to the P site of the 50s subunit of the bacterial ribosome. It is also worth noting that supportive care plays a role in managing the disease, especially in…

Exercise 2: Observing Bacteria Cultures in Yogurt Firstly, we created an incubator using a Styrofoam cooler with a removable lid and a small hole in the top which was used for placing a 7 watt light bulb in order to maintain a Microbe growing temperature of 35-37° Celsius. We also monitored the temperature with the use of a thermometer. A teaspoon of yogurt was then placed into a clean plastic container with lid. The container was then placed in the Styrofoam incubator, which was not…

Write an essay on the structure of proteins, emphasising the forces that sustain their three dimensional structures. Introduction MORE Proteins are nitrogenous organic macromolecules constructed from a base sequence of 20 amino acids at the ribosome in cells. There are over 100,000 different proteins encoded by thousands of different genes within the human body. They all perform different functions e.g. antibodies providing immunity and enzymes catalysing metabolic reactions. The…

Figure 1: Shows the gene expression changes found in Arabidopsis after the insertion of the IRX1, IRX3, and IRX5 mutants(Brown). 1A shows the principal component data collected from the targeted areas of the plant(Brown). 1B shows a comparison of gene expression of the base and tip of the stem and the change of level(Brown). 1C shows the slope of genes most likely to be related to IRX3(Brown). From Figure 1B, it is shown through analysis that there are several hundred genes that show an increase…

The Extraordinary Science of Microbiology There are a wide variety of microorganisms in this world. The major groups of microorganisms include bacteria and fungi. These microorganisms are found all over the earth. The study of microorganisms started in the mid-1600’s. Most people believed that microorganisms only spread deadly diseases, but scientists proved that microorganisms can also be beneficial to human life. The wide variety of microorganisms that are found everywhere are most well…

1.0 Introduction – What is diabetes Mellitus? Diabetes mellitus is a progressive disorder of chronic hyperglycaemia due to insulin deficiency or resistance and in some cases both which affects people of all ages. The chronic hyperglycaemia causes a range of macro- and microvascular complications. Macrovascular damage leads to increased prevalence of heart disease, stroke and peripheral vascular disease whereas microvascular complications can cause diabetic retinopathy, neuropathy and…

Sandra Peart. Biology Assignment 2 Task1 AC1.1 Major Components & Function of Blood. The four major Blood Components are •Plasma •red cells •white cells •platelet •Plasma is the liquid part of the blood that is made up of 55% fluid, this is the blood’s liquid medium, by itself is straw-yellow in colour. The total volume of blood plasma is about 2.7-3.0 litres in human. The plasma carries carbon dioxide , hormones and waste. •Red blood cells •The red blood cells are called…

Introduction: Chlamydomonas is a unicellular green alga that contains two flagellas that are used for swimming. It is found in fresh water, in oceans, and in soil. Chlamydomonas are easily grown and controlled. We study chlamydomonas because we are able to easily deflagellate them and then allow them to regenerate their flagella using different chemicals. Due to this characteristic, we are able to study how flagella growth is affected and the rate of flagella growth once deflagellated.…
