![]() ![]() In the case of human mRNAs, these modifications occur – with the help of appropriate enzymes – in the cell nucleus, which is where the mRNA is formed, based on the DNA found in the nucleus. It is a relatively complicated process, which involves, among other things, adding appropriate structures on both ends of the mRNA strands: a so-called cap is added at one end and a poly(A) tail at the other. ?Cellular mRNAs must be properly prepared to be the matrices in the protein synthesis process. Viral mRNAs are very similar to any other mRNAs found in a human cell, so the virus can use human cellular machinery to produce its proteins. it is the so-called messenger RNA (mRNA). After infecting the host cell and entering the cytoplasm of that cell, the viral RNA strand serves as a matrix for the synthesis of viral proteins, i.e. The SARS-CoV-2 coronavirus belongs to the group of RNA viruses, which means that its genetic material is a single RNA strand. The research is financed by the Foundation for Polish Science, from the European Union funds. The answer to one of such quite detailed but significant questions is going to be provided by a research group working under the supervision of Professor Andrzej Dziembowski PhD., from the RNA Biology Laboratory of the International Institute of Molecular and Cell Biology in Warsaw. ![]() However, several details relating to the production of virus proteins in host cells still remain unclear. We understand how it spreads and penetrates into human cells we recognise its genome and the proteins that build it. We already know quite a lot about the SARS-CoV-2 coronavirus. ![]()
