could determine "how much" transcription is necessary. Positive control is the method that can help start the transcription through protein binding and is often regulated by things such as glucose. On the other hand, negative control can help stop transcription when necessary. This type of control also involves the binding of a protein, but it is a repressing protein as opposed to an activator. Although transcription is different in prokaryotes and Eukaryotes, there are many similarities. In…
Assessment of enzyme producing efficiencies of endophytic fungi Extracellular enzymes assay was conducted to investigate the production of enzymes by the endophytic fungi Amylase activity Amylase enzyme was assessed by growing the fungi on glucose yeast extract peptone (GYP) agar medium (glucose- 1g, yeast extract- 0.1g, agar- 15 g, distilled water 1000mL and pH 6) containing 1 % soluble starch after 5 days incubation , the plates with fungal colony were flooded with 1% iodine and 2% potassium…
Homeostasis is defined as keeping the variables and conditions of a system constant and regulating the internal conditions. In a biological system at the cellular level, this can be defined as the process of maintaining stable conditions inside a cell, such as a normal pH, salinity, and ion concentration, to keep the cell healthy. There are several parts of the cell that play a role in homeostasis, but one of the more prominent ones is the phospholipid bilayer membrane. The cell membrane…
LO 2.1 I understand that free energy, the portion of a biological system’s that can perform work when temperature and pressure are uniform throughout the system, is used in systems to cause change. I also understand that empirical data proves all organisms require a constant energy output to maintain organization, to grow, and to reproduce. (Campbell 119-123) LO 2.2 I understand that although free energy is always required in living systems in order to maintain organization, to grow, and to…
cell such as Erthrocyte or osteoclast.The relationship between epignetics and stem cells paved a pathway to an experiment relating to the relationship between TET, a protein that oxidizes certain kinds of DNA and stems cells and its properties when it is both modified and unmodified, by OGT, an enzyme that modifies other proteins with different materials such as sugar. Gene expression is the…
Many endosymbiotic theories have figured in opinion about the differences between prokaryotic and eukaryotic cells. More than 20 different versions of Endosymbiotic theories have been presented in literature to explain the origin of eukaryotes and their mitochondria (Martin, Garg and Zimorski, 2015, p.1678). A Prokaryotic cell contains structural components such as: Cell wall is made of peptidoglycan. Gram-positive bacteria contain a thick cell wall with many layers of peptidoglycan…
While reading the book Genome by Matt Ridley, I started to hone in on some of the key topics and main ideas to take away from this novel. It was a very interesting read that introduced new ideas to me. Many of the ideas in the book applied directly to our Biology class. Some topics that were covered in lecture can be directly applied to the book. Matt Ridley talks about many important things in his novel; however, I feel as if the chapters of life, species, and environment are the most…
This novel route, have several characteristics to distinguish them from the more traditional target specific route available. The difference between normal skin and the lip skin. The labial skin on our lips looks clearly different from the rest of our body [38]. That is because it is much thinner in comparison to normal skin. Skin is divided in three separate layers - the stratum corneum, the epidermis and the dermis [39]. The protective stratum corneum is the outer layer that we can see, the…
Lead Identification (LO): Lead compounds bind to target receptors, and shows potentially therapeutic pharmacological activity, and may contain similar structures and functional groups. Lead compounds are used as a foundation for drug development and may be modified structurally for greater pharmacodynamic efficiency and potency.1 One source of determining lead compounds is by assaying libraries through HTS. Researchers analyze the drug’s ADME properties (Absorption, Distribution, Metabolism, and…
year 2009 in Northern England, for every 100,000 males, 16 had DMD (0.016%). DMD affects males before the age of 5 due to a gene mutation on the X chromosome, thus causing males to be more at risk. The gene mutation prevents the translation of the protein dystrophin…
