Molecular biology, along with ‘GenBank’ plays an important role in genetic disorders. More than 200 single-gene disorders have been detected. It determines the molecular genetic defects in various diseases. These include amongst others cystic fibrosis, sickle cell anemia, and thalassaemia. Modes of inheritance are essential knowledge in genetic counseling and...
Introduction Biological evolution refers to descent with modification. Biologically, descent is taken to refer to the concept of passing traits from one generation to another while on other hand modification is regarded as the change in the composition and frequency of the gene.This is the concept through which the modern...
Prokaryotes are organisms that lack a cell nucleus or any other membrane-bound organelle, while Eukaryotes possess both. The nucleus is one of the most important structures required in living organisms. The nucleus can be thought of as the ‘brain’ of the cell. Mostly Prokaryotes are single-celled or unicellular, except the...

Application of the studied statistical information allows translating theoretical bases into a practical activity that stimulates a student’s professional and creative development as a specialist....
Introduction Etiologic agent Brucellosis is a common infection that affects man, swine, goats, and cattle, although it rarely infects wild mammals such as deer in the United States. The disease is responsible for the occurrence of abortion in cattle (Ingebrigtsen, Ludwig, Arlin, & McClurkin, 1986). Brucellosis is caused by bacteria...
Chapter 1 The first chapter of the book Why Evolution is True by Coyne is an introduction to evolution and how it is driven by natural selection. Charles Darwin coined the theory that all life forms resulted from evolution, which was largely propelled by natural selection, which bases on the...
Introduction Among many exotic and extinct fauna, thirteen species of Darwin’s finches, namely Geospiza fortis, G. scandens, G. magnirostris and G. fuliginosa harbor Galápagos Islands, Santa Cruz, and Daphne Major (Grant & Grant, 2008). According to Grant and Grant (1995), these species have displayed remarkable evolutionary adaptations to survive harsh...
Introduction Methicilin Resistant Staphylococcus aureus (MRSA) is a bacterial strain that is resistant to beta-lactam antibiotic penicillin. It is also known as multidrug resistant Staph. In the hospital set up, patients who make use of invasive devices, have compromised immune system, and have open wound have greater chances of getting...
Radiation results from the decay of unstable nuclei to give out particles that could destroy normal tissues leading to diseases such as cancer. Radioactive elements are referred to as ionizing radiations that can impact the chemical and physical traits of the molecules they are exposed to. Radiation comprises high-energy particles,...
Chlorophyll is the molecule found in green plants that absorbs sunlight necessary for the process of photosynthesis for the sustenance of plant lives. Situated in the chloroplasts of green plants, it is what constitutes the green color of green plants. When light falls on plants, chlorophyll pigments take in blue...
The effects of environmental pollution on the global marine ecosystem, as well as local ones, have been tremendously adverse, with multiple species having become extinct or approaching the stage of extinction. Therefore, strategies for restoring the ecosystems that said organisms need to survive and thrive must be introduced into the...
Introduction Education is a vital need of modern society. It allows people to develop their skills and talents so that to further use them for their own prosperity and for the glory of their countries and continents. In Africa, the issue of education is rather burning as the weak economies...

A study conducted at Paul Sabatier University found that societal shifts caused ancient hunter-gatherers to prefer male horses. The research used DNA from the remains of ancient horses to determine alterations in animal husbandry preferences. The study of DNA, starting with the human genome, has broadened to allow researchers to...
The overall aim of this report is to explain the use of chromatography procedure in separating the components of lycopene. Conjugated polyenes with multiple single or double bonds alternating give fruits and flowers the different colorations feature. According to Answers.com (2010) lycopene is a red carotenoid pigment and a polyene...
The brain is one of the most complex body organs, and addressing the issues that relate to it can be sophisticated as well. The TED Talk video gives an elaborate description of the common misunderstanding of the brain like a bag of chemicals and that related ailments can be resolved...
In 1998 French researchers Christian Vaisse, Karine Clement, Bernard Guy-Grand & Philippe Froguel published an article A frameshift mutation in human MC4R is associated with the dominant form of obesity in the scientific journal Nature genetics. The article implies exploring the human melanocortin-4 receptor and its relation to obesity. The...
The incidence of malaria has been increasing at an alarming rate. Nearly 3000 million people are reported to be affected annually and 1/3 of them die. Confronting malaria has achieved good progress in the elimination of mosquito species that would carry Plasmodium parasites by eradiation of breeding grounds and using...
Digestion Process The process of digestion occurs in the digestive system. This process is the source of energy for all living creatures. Digestion involves the breakdown of large junks of food into small molecules that can be absorbed into the system. The process occurs in three key steps. These are...
Heart anatomy The heart consists of four chambers through which blood inconsistent flows. They are divided by heart walls that are made of cardiac muscle as the whole structure. The upper compartments are called atria (singular: atrium), and the lower ones are ventricles. Atlas of Human Cardiac Anatomy interactively shows...
Introduction Chemistry education is aimed at preparing one for better living. Chemistry occupies a central position among science subjects. Chemistry is conceptualized as gaining knowledge problem-solving and constructing personal understandings. Chemistry can be defined as using our knowledge of how matter is put together and how it interacts with other...
