Biotechnology is defined as “the exploitation of living systems and biological processes to develop tools for technological use”. It may be applied in areas such as industry, medicine, environmental sciences as well as computer design. The field of biotechnology is very broad because there is such a wealth of biological phenomena which we could harness for human benefit. However, although...

Viruses are the smallest microorganisms in life and cannot be seen by naked eyes or with light microscopy. They are considered as a contagious agent that is only regenerated within the host cells of other living organizations and can infect all living organisms in the earth, from animals and plants to microorganisms, including bacteria and the archaea. Viruses can be...

Everyone knows the importance of exercise, but the people are not much aware of the importance of protein and how it affects the human body in muscle recovery. Actually, muscle is starving for protein after high-intensity exercise. we all know that carbohydrates are a crucial fuel source throughout training, also perform a major role in helping recovery after exercise. However,...

Introduction Growing crops hydroponically is an alternative to traditional soil farming methods (7). Hydroponics systems consist of a water-based solution enriching in nutrients, without the use soil (2). Commonly an artificial medium is used to provide support for the plant as soil is not being used (2). Hydroponic systems started in 1920 and have dramatically evolved in a variety of...

Agriculture and food security under shifting climatic conditions The global population is increasing day by day and is expected to increase further by 2050 (Ringler et al., 2016). This larger population will exert pressure on the prevailing resources. Further, due to urbanization and unbalanced use of fertilizers and pesticides, land for agriculture is decreasing rapidly. Despite technological advancements including mechanization...

INTRODUCTION Access to DNA is required to regulate the gene expression, and this access regulated by many factors such as chromatin remodeling or histone modification. According to Vogel-Ciernia and Wood (2014), chromatin remodeling is a movement of nucleosomes along DNA by the aid of chromosome remodeling complexes (CRCs) that is composed of four large protein families which are BAF (SWI/SNF),...

Nutrient solutions and fertilizers impact plant growth in many ways. According to Teaming with Nutrients by Jeff Lowenfels, plants that experience nutrient deficiencies, are more likely to experience informalities such as wilted or yellowed leaves. In order for a plant to sustain itself, it must have seventeen main elements. Many everyday fertilizers and nutrient solutions provide these elements. The most...

The effects of changing temperature and pH conditions on the activity of the β-galactosidase enzyme and its affinity for ONPG were studied. A standard curve was developed as a control, and was used to obtain the assays for the 6 different reaction rates studied, corresponding with the 4 temperatures and 4 pH’s. The reaction results were measured for its absorbance,...

Introduction Apoptosis refers to normal and coordinated death of cells where cells degrade their cytoplasmic contents and DNA. [1] It takes place in multicellular organisms as a programmed response of defense against noxious agents. It can also take place during the regulation of cell populations within the tissues. This analysis will further the definition provided above and explore causes of...

The qualifications all biotic beings meet are not met by viruses on the grounds that there is a lot that a virus is unable to do. A virion cannot maintain homeostasis, or regulate its internal processes because it does not have the anatomy to do so, simply because a virus is not made up of cells. A virion is, fundamentally,...

Introduction Stem cells are formatively crude, undifferentiated cells that have the ability to make new duplicates of themselves (self-reestablish) and to practice (separate) into different other cell types, for example, blood, muscle, and nerve cells. Customarily foundational microorganisms have been classified into two primary gatherings: embryonic immature microorganisms and grown-up undifferentiated cells. HESCs (Human embryonic stem cell) are separated from...
