Today we will try to introduce you to one of them – replication. When thinking about genetics, most of us think of the DNA helix. Two lines spinning around each other creating a screw-like shape. However, although genetics is actually based on genetic material in the form of DNA, many different processes are involved. What...
One of the most important skills for a cell is the ability to divide. We know two cell divisions - meiosis and mitosis. Today we will delve into the second one – mitosis. What is mitosis? Mitosis is the process by which one cell divides into two identical daughter cells. During this process, chromosomes are...
Every year, high school graduates struggle with the decision of whether they should study medical analytics. They have to choose which field to choose and what profession they want to pursue in the future. High school graduates who took the Matura exam in natural science subjects, such as chemistry and biology, especially have a large...
The pharmaceutical and biological medicines market is full of all kinds of medicines for most diseases. New OTC and generic medicines appear in pharmacies. However, in addition to the most well-known pharmaceuticals, doctors are increasingly using a relatively new creation in pharmacy - biological medicines.

Monkeypox, which is linked to the now-eradicated smallpox virus, is endemic in parts of central and west Africa. UK...
A new sub-strain of the Omicron variant called "stealth omicron" has been detected in more than 40 countries and can escape even RT-PCR testing, the UK has said. Sub-strain BA.2, commonly called "stealth omicron", has raised fears of a stronger wave across Europe. So what is this Omicron subvariant and how dangerous is it? Here's...
Many will ask "flurone covid what it is", and although there is not much information yet, according to the Israeli Ministry of Health, it is a simultaneous infection of COVID-19 and influenza. The word Flurone covid is a combination of influenza and rona, a contraction of the coronavirus, although it is not a scientific name....
Since the release of this variant, we haven't stopped hearing omicron news, so here's another one "Half of Europe will be infected with Omicron in short order". The World Health Organisation(WHO) has warned that half of Europe will have been infected with the Omicron variant of Covid within the next six to eight weeks. Dr...
In the last year there have been many developments and news around PCR tests, these days a new approach has emerged by LMU chemists could help to significantly improve PCR-based diagnostic tests. The enzymes used are activated by pulses of light. DNA polymerases and other DNA-modifying enzymes are essential tools in biotechnology and diagnostics. They...
There is information all around us about an increased number of cases of our pets getting sick, the Avian flu. Specialists tell us to keep an eye on our cats so that they do not leave the house to avoid contact with sick birds. Can this disease be transmitted to humans? And if so, how...
With the ongoing summer period, many plants begin to bloom. Unfortunately, this process then involves the production of a large amount of pollen, which is then carried by bees to disseminate certain plant species. Why unfortunately? Many of us suffer from a condition called allergy, which is very often caused by contact with various types...
What is malaria? Malaria is a mosquito-borne disease caused by parasites in the insects' bodies. It is a serious disease and sometimes fatal. The exact species of mosquito that is involved in the infection process is Anopheles. The disease begins with the bite of a mosquito carrier, which, together with a puncture of the skin,...
With the release of Christopher Nolan's Oppenheimer, the public became interested in the atomic bomb and radiation itself. Remembering the explosion in Hiroshima, we witnessed how a large influx of nuclear radiation affects the human body. Many of us also survived the explosion of the Chernobyl power plant, where a real threat of radiation sickness...
Meeting with articles or scientific books related to biology, we often come across words such as meiosis and mitosis. Both, despite their mysterious name, play a very important role in the life of the cell. Unfortunately, we often confuse them due to similarities in the name and location of the action. Thanks to this article,...
In many media we are increasingly hearing about autoimmune diseases or autoimmunity. We hear how dangerous they are for the patient and how often they appear in our population. Is there any way we can defend ourselves against these diseases? And what is the immunization process itself? What is autoimmunity Autoimmunity is manifested by the...
Our entire world is made up of microorganisms and microbiology. We ourselves do not realize how often we encounter bacteria both good and harmful to our bodies. Many products, ready for purchase on the Gentaur website, belong precisely to the equipment needed in microbiology laboratories. What kind of work takes place in such a place,...
The vacations are fast approaching and so is the danger of being bitten by a tick, today we are going to lyme disease. Although these small insects seem innocent because of their size, they carry a very dangerous disease called Lyme disease. How to protect yourself from this insect and what to do when you...
Multidrug resistance is the insensitivity or resistance of a microorganism to the administered antimicrobial medicines with different structures and the molecular formula (Tanwar, Das, Fatima, & Hameed, 2014). According to the World Health Organization (WHO), the resistant microorganisms that include bacteria, fungi, viruses, and parasites are able to fight the antimicrobial drugs. As a result,...
Tuberculosis, which is a curable disease nowadays, continues to threaten our health. New cases and even deaths are still being reported. In 2021, around 1.6 million people died from TB, including 187,000 people who also have HIV. The disease still ranks as the 13th most common cause of death. Together with COVID-19 disease, it ranks...
The gene transfer technique is widely used in genetic research. It is one of the indispensable tools used in cloning, research into gene function and regulation and in the production of recombinant proteins. This process is divided into six methods: transformation, conjugation, electroporation, gene transfer by liposomes, transduction and direct DNA transfer. In the following...
Despite new and standardised treatments, HIV continues to be a major problem in many countries around the world. According to the WHO, since the beginning of the pandemic some 84 million people have been infected with the virus and 40 million have died.
