Hello guys!  The elevating cases of corona in the world forced researchers to discover antibiotics.  scientists experimenting and researching continuously to develop vaccines or therapy that may help to beat the corona crisis. So, one of the therapies that doctors believe to experiment on patients is plasma therapy. Plasma is a watery fluid of the blood. This plasma is consists of corpuscles and thrombocytes in addition to that plasma also contains some proteins (immunoglobulin) which produce antibodies. Our body works on the principle of the immune system. The basic principle of the immune system is that it forms antibodies against any foreign antigen that enters the body. Our immune system memorizes this antigen and this is called the primary response. If the second time again this same antigen comes into the body by any means then our antibody recognizes it and neutralizes this foreign antigen.  This principle is becoming helpful for experimenting against ...

                                        Coronavirus Coronavirus is an infectious disease that is spreading rapidly all over the world. More than 20 lakh people of the world have been affected by this virus and incoming time its chances of increase will be more. It is coming from the Wuhan, the capital of China on 29 December 2019 and since then it is spreading more fastly. Symptoms - Fever, cold, cough, fatigue, diarrhea are general symptoms of this virus.  Older people and the child under 10 years of age are prone to this pandemic disease. The symptoms of this disease will appear between two to fourteen days. The people having a pre-existing disease like cancer, respiratory problems and diabetes have more risk to get the infection. Mode of transmission - This virus is inactive until they do not get any host body to replicate their genome. After entering into the ho...

                             Transgenic Animals & ethical issues  Hello guys! on this blog, we are going to discuss what are the transgenic animals and what are the issues related to that. So, guys, transgenic animals are those animals that have their DNA  manipulated so that the extra foreign gene can be expressed. There are multiple examples of transgenic animals like sheep, cows, mice, rats, etc. Reasons for developing transgenic animals -   To the understanding of gene regulation and their effect on normal physiology of the animal and its development. For example, we can study various growth factors. The study of the disease can be done by studying genes, which are responsible for causing disease in human and their treatments. Biological products can be produced by introducing the portion of DNA, which codes for a particular product into transgenic animals. For exa...
