Gram-positive bacteria

They are made within the nucleolus from 60% RNA and 40% protein, and consist of two subunits, one large and one small. When produced, the subunits stay separate to exit through the nuclear pores: it is only because of their miniscule size that they can fit through. Many ribosomes then bind themselves to the RER, although some stay free in the cytoplasm. Free and bound ribosomes both create polypeptide chains, which are used to make proteins. To create a polypeptide chain the large and small…

Moalem talks about how cholesterol rises too. Like when you consume alcohol, your body detoxifies it and then extracts calories from it. It's a difficult process that involves many different enzymes and a lot of organs, although most of the process takes place in the liver. First, an enzyme called alcohol dehydrogenase converts the alcohol into another chemical called acetaldehyde; another enzyme—cleverly called acetaldehyde dehydrogenase—converts the acetaldehyde into acetate. And a third…

aseptic technique is the collection of procedures and steps performed to ensure both the cleanliness of the laboratory setting, and more importantly, the purity of the components used; that is to say, to ensure that no unknown contaminants such as bacteria or cells can compromise the procedures of the experiment (examples of such techniques include wearing the proper personal protective equipment, cleaning important surfaces with ethanol, and pipetting liquids in…

nitrification process and both their protein synthesis use the same methionine amino acid function. It was thought that modern bacteria evolved from archaebacteria but new scientific methods of DNA molecular sequencing concludes that they are not that primitive and the fairly homogenous group have evolved just as much (Ladiges, 2010). Instead of being the related to bacteria, in fact it is the ancestor of…

for a viral infection. Another type of selective pressure is not completing a full prescription. If a patient stops taking an antibiotic before they should, all of the disease causing bacteria may not be dead yet. This greatly increases the chance of recurrence and a greater chance…

What are disease-causing bacteria and how harmful could they be? By their name, disease-causing bacteria are bacteria that cause disease. The effects that they have on the human body, or any living organism, can range from mild to severe. Fortunately, we have antibiotics to help prevent the spread of infection and protect our bodies against infectious bacterial diseases. Antibiotics, also called antimicrobial drugs, are drugs that fight off infectious disease caused by bacteria. With the…

With the rate at which our planets population is growing, what are we going to eat when we run out of room to plant crops, raise animals? There is always the option of genetically modified organisms or GMO’s, meats that are grown in labratories, algae, or even insects, but all of these are “temporary fixes” to the real problem. How can we sustainably survive on this planet at all if we continue down this path of over consumption? According to the Non GMO Project, GMO’s are defined as living…

Introduction Microbes are essential to everyday life. Going from the basic food we eat to biogeochemical cycles, if we didn 't have biogeochemical cycles we would no longer have any of the resources that we have now; for example, there is plenty of nitrogen in the atmosphere but it 's all not available until it has been fixed, and that is when the microbes come in and changes the nitrogen in a way that is usable. Humans come in contact with microbes every day there is never a time there are…

invading and “chop up” their DNA. This defense mechanism is composed of clustered regularly interspaced short palindromic repeats found within the genome of bacteria. This is the origin of the CRISRP acronym. These CRISPR sequences are specific patterns of DNA sequences that are capable of being edited out of genes. Using the CRISPR system, bacteria are able to destroy the genome of invading viruses and thus prevent the virus from being able to replicate and survive in its host.…

leaky gut syndrome. Under ordinary circumstances, your gut has just enough permeability to allow the absorption of vital nutrients. However, certain dietary and environmental factors can greatly increase your intestinal permeability, allowing bacteria, undigested food, microbes, and candida to leak into the rest of your body. This can result in chronic illness. Leaky gut syndrome is most commonly triggered by: Inflammatory Foods – Gluten is an inflammatory food, and for those who are…
