Introduction Viruses are considered as extremely successful predators as they can replicate and control the host cell synthesizing machinery. Viruses have coevolved with their hosts and thus have limited pathogenicity in any immunocompromised natural host. Viruses can exist in two forms: Extra cellular virion particles Intracellular genomes. Virions are more resistant to physical stress than genomes but are susceptible to...

In my opinion I don’t necessarily believe viruses are alive because of the fact that viruses can't reproduce on there own, they need a cell to reproduce. If you had a looser definition of alive then maybe they can be considered alive. I also beileve there not alive because according to the seven characteristics of life for something to be...

The corona viruses (2019 -ncov) infecting humans appeared in Wuhan, China, at the end of December 2019. Since the identification of the outbreak the infection quickly spread. This illness is a type of decease that transmits between animals and humans. Based on the articles that I read the infections of human to human transmission remains unclear. In contrast, human to...

Viruses are the most common biological agents in the sea typically numbering 10 billion per litre. They mostly infect all organism, can undergo rapid decay and replenishment and influence many biogeochemical and ecological process including nutrient cycling, system respiration, and particle size distribution and sinking rates, bacterial and algal biodiversity and species distribution, algal bloom control, dimethyl sulphide formation and...

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,...

Viral respiratory infections can cause many different illnesses related to the respiratory tract. These diseases may range from mild infections to more severe ones that can even lead to death. The most common respiratory disease is known as a cold, which is a mild infection that affects the upper respiratory tract and it is harmless in most cases. Common colds...

Bacteria - these are single cell microorganism that come in many shapes and forms these can be ball, rod or spiral shaped. most bacteria's are not harmful and some can be helpful less than 1 percent of these are infectious which can multiply in the body leading to disease. They can produce toxins that can make someone very ill. bacteria...

INTRODUCTION Influenza viruses are a virus that infects the respiratory tract of mammals and usually can cause fever, muscle pain, severe headache, sore throat, fatigue, coughing, and weakness. It is the Orthomyxoviridae family of enveloped viruses and a significant cause of respiratory infections worldwide (Bahadoran et al., 2016). It can be transmitted through the air by coughing or sneezing and...

Viruses a foe which has affected the past and has now turned modern-day living into an almost apocalyptic like state due to the appearance of Covid-19. Along with being one of the most heavily studied areas within science, although a conclusive answer on whether viruses can be considered apart of the living or nonliving is still being debated. The virus...

Viruses have continuously challenged our perception of what ‘living’ means. The scientific community have constantly debated whether viruses are classified as living or non-living organisms. Viruses are very important complexes of biochemical that influence all types of living organisms including bacteria, yeast, plants and animal cells. Viruses are blobs of RNA or DNA surrounded by a coat of protein. They...

Viruses’ evolutionary history has been an interesting but challenging topic for the cell biologists and virologist. Due to their great variety, it has been difficult for biologists to classify them and how they connect to the traditional tree of life. It can express genetic elements that can move between cells. They can represent organisms that lived freely before becoming parasites....

Biology has been playing a very big role in our society since the ancient times until now. As one of the branches of science assigned in studying life and living things, it allows us to discover and learn about different organisms through testing, reviewing and experimenting using scientific research methods. Biology allows us to learn about the structure, function, behavior...

The transformative history of infections speaks to an interesting, though cloudy, theme for virologists and cell scientists. Due to the extraordinary assorted variety among infections, researcher have battled with how to characterize these elements and how to relate them to the traditional tree of life. They may speak to hereditary components that picked up the capacity to move between cells....

Abstract There are seven types of coronaviruses appeared till now and they are different in their pathogenicity and the degree of the severity of the symptoms they cause. Phylogenetic analysis should be conducted in order to know the origin of the lethal viruses to be able to find treatments for them. In this essay, what have been found so far...

Introduction COVID-19 is a worldwide pandemic involving the vast spread of a type of viruses called the Corona virus. These viruses are positive-stranded RNA viruses having a crown-like appearance when viewed an electron microscope. It belongs to the subfamily Orthocoronavirinae of the Coronaviridae family (order Nidovirales) and is divided into four genera of CoVs: Alphacoronavirus (alphaCoV), Betacoronavirus (betaCoV), Deltacoronavirus (deltaCoV),...

What Is Corona Viruse (COVID-19) Corona viruses are a wide group of viruses that in animals and humans may cause disease. Corona viruses are known to cause respiratory infections in humans ranging from mild colds to more severe diseases such as Middle East Respiratory Syndrome, and severe acute respiratory syndrome (SARS). Since being first identified in southern China in 2002,...

Coronaviruses are single-stranded RNA viruses, about 120 nanometers in diameter. They are susceptible to mutation and recombination and are therefore highly diverse. There are about 40 different varieties and they mainly infect human and non-human mammals and birds. They reside in bats and wild birds, and can spread to other animals and hence to humans. The virus that causes COVID-19...

Abstract Mycoviruses are significant widespread viruses found to be infecting all major groups of plant pathogenic fungi. Mycoviruses require living cells to replicate like other animal and plant viruses. These viruses are transmitted through cell division or during spore formation. Most of the mycoviruses have double strand RNA genome, and few are known to have positive single strand RNA genome,...

We know how the COVID-19 pandemic began: Bats near Wuhan, China, hold a mix of coronavirus strains, and sometime last fall one of the strains, opportunistic enough to cross species lines, left its host or hosts and ended up in a person. Then it was on the loose. What no one knows yet is how the pandemic will end. This...

Gene regulation is the way genes are expressed, and it starts with the central dogma. Gene regulation starts with the DNA which makes mRNA which then makes proteins. Prokaryotes, which are bacteria (for example E. coli), eat whatever we eat; therefore, if we drink milk, the bacteria will break down the lactose using gene regulation (Anderson, 2011). Bacterial genes are...

Introduction Bacteria and bacterial viruses, commonly known as bacteriophages, represent two crucial entities in microbiology that have significantly influenced biological research and biotechnology. While bacteria are unicellular microorganisms classified as prokaryotes, bacteriophages are viruses that specifically infect bacterial cells. Despite their distinct classifications and fundamental differences in structure and lifecycle, bacteria and bacteriophages exhibit several similarities that are intriguing from...
