Molecular Biology Essay Examples

Athlete utilizing insulin like growing factor -1 ( IGF-1 ) to heighten public presentation deficiencies scientific grounds, but much anecdotal grounds seems available to propose its used in the athletic sphere. Rosenbloom ( 2007) discusses how Children with growing failure due to a lack in IGF-1 are frequently prescribed IGF-1 to promote and speed up […]

Biologists employ microscopes and biochemical tools to analyze cells. The study of cells faced limitations in the past due to their small size, but Robert Hooke’s observation of deceased oak tree cells in 1665 and Anton van Leeuwenhoek’s invention of lenses and optical aids revolutionized cell investigation. The ability to observe through a microscope depends […]

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 spread more easy than the smaller molecule. B. The nature of plasma membrane. If the membrane is composed of lipid part. . merely lipid soluble molecules […]

Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the […]

The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver, blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed, ammonium sulfate was added to the supernatant, chilled and then spun […]

This study focused on exploring and analyzing different methods of protein solubilization and assaying, with bovine liver protein serving as the test sample. The effects of several solvents including ethanol, water, PBS, PBS+1% Triton x-100, and PBS+2% SDS on protein solubilization were thoroughly investigated. Protein quantities dissolved in these solvents were measured using Bradford and […]

 Introduction Over the course of the last few weeks, we conducted experiments in which our goal was to successfully ligate EGFP cDNA into pET41a(+) in order to transform our recombinant expression plasmids into clones of E. coli. After growing these cultures on varieties of agar plates, we attempted to isolate our recombinant plasmid DNA and […]

Research Question: “What are the economic efficiency and overall environmental benefits of commercializing Bt-Corn breeds?” “Abstract This paper discusses and evaluates the positive and negative aspects of Bt-Corn, a transgenic maize developed through genetic engineering and biotechnology methods. It also addresses controversial issues surrounding Bt-Corn, and ultimately concludes that the commercialization of Bt-Corn breeds has […]

The main focus of the Human Biology Unit 1 Assignment is the study of cells, including their structure and function. Cells are small structures that are surrounded by a membrane and contain an aqueous solution. Within cells, there are various organelles that have specific functions. Eukaryotic cells possess several organelles such as the nucleus, ribosomes, […]

Introduction A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk, 2013). The membrane is necessary for sustainability of the cell’s life, it separates the cell from the outside environment, and is responsible for diffusion, exocytosis and endocytosis, and transport. It can be damaged […]

Arabidopsis thaliana, also known as ‘mouse ear cress’, is a small weed classified as a dicotyledonous angiosperm. It possesses two leaves in the mature embryo and its seeds are enclosed within an ovary in the flower. Similar to other plants, Arabidopsis thaliana is autotrophic and can produce its own food through photosynthesis. It remains immobile […]

RNA polymerase is a crucial enzyme in human cells that produces a template of the cell’s DNA, essential for protein production. RNA, acting as the enzyme, uses genes from DNA to create RNA chains with specific genetic codes expressed on mRNA. However, if a toxin inhibits RNA polymerase during transcription, it hampers mRNA production. Once […]

Practice Questions for FALL FINAL Biology KEY Note: These are a few sample questions that you can work through for more practice with genetics and experimental design. You should also review the evolution and experimental design quizzes and exams. These questions do NOT cover all of the material covered this semester. Completion of these questions […]

By utilizing our knowledge of the genetic code, transcription, and translation, we can elucidate the mechanism through which a mutation can cause a single gene disorder. In this discussion, we will offer an illustration of such a disorder. This will encompass information concerning the gene that is affected, its influence on the final product generated, […]

In studying evolution, there has been much debate over the origins and evolutionary maintenance of sex. This represents a great challenge in evolution as it appears that the vast majority of animals and plants reproduce sexually. One component compounding the mystery is the two fold cost of sex, that is, there is a cost to […]

Human beings-as is every form of life on Earth-are the product of millions of years of random, unintentional mutations to the DNA of, at every stage, a less complex and more poorly suited organism. It is a process whereby something of low entropy keeps decreasing; whereas in the physical world, the general rule is the […]

In the previous activity, you learned that DNA contains instructions for making proteins and the basics of protein synthesis. In this activity, you will use your knowledge of written text and translation to decode a secret message and explore the effects of different mutations on protein production. Specifically, you will focus on the genetic mutation […]

Over the past several years Genetics has become a leading link to understanding how our body works. By mapping out deoxyribonucleic acid, or DNA, scientists plan to find cures for various diseases, develop better, more efficient drugs, grow new organs, evaluate environment hazards, and eventually build a human being. Inside of every single cell in […]

This report offers a comprehensive overview of the main theories on the aging process. As there is no universally accepted theory, these discussed theories serve as potential explanations for aging, with each hypothesis holding approximately equal likelihood. The focus of the explored theories ranges from DNA mutations and replication at the molecular level to wear […]

The articles The Cancer Killer, Insurance, and The Enemy Within all highlighted many concerns and problems that arise with cancer. They not only introduce medical aspects, but also the societal aspects as well. The articles also told of many procedures and ideas that are currently being studied and tested, and they highlighted many important breakthroughs. […]

According to Tomasello (1999), the primary difference between human cognitive development and that of other primates is our ability to comprehend others’ intentions, engage in abstract thinking, solve environmental problems, and use language. This viewpoint contrasts with Freud and Piaget’s structural-organismic perspectives because it suggests that developmental stages are universal. B. b. The child’s psychological […]

The Perfect World. Imagine a world full of Lebanon James, Adrian Gonzales, Beyond, and Brad Plat, which was developed by the parents that chose to transmit featured genes into their fertilized eggs through IF (in vitro fertilization clinic and these so-called genetic engineers are able to mutate both internal and external physical traits exactly the […]
