 Coronavirus Infectious Disease-2019

Covid-19 is a newly emerged highly infectious strain affecting around million of people around the globe. It is termed as corona due to its crown like shape. It is carrying spike proteins with specific gene sequence that is responsible for causing the infectious condition. Spike proteins penetrate the specific cell to cause the infection. Due to the presence of specific mutations, the infectivity rate of the pathogen is higher as compared to other members of coronavirus family. 


Various strains of covid-19 are being emerged due to acclimatization and genetic changes due to the failure of mankind to fight with the infection.

The emergence of covid-19 was first reported in Wuhan city of Chine in December, 2019. The virus is a mutant form of SARS (Severe Acute Respiratory Syndrome) The virus is found to be highly contagious due to the presence of a spike protein that tends to bind specifically receptor sites present on lung tissue. The pandemic created an alarming situation and everything halted due to this deadly and contagious virus. There are some controversies regarding the emergence of virus, as some people assume that virus has been created by biological method by Chinese scientists with some unforeseen motives.  However, efforts are still on to completely eliminate the virus to let mankind take a breath of relief. Researchers have sequenced the whole genome of the virus, and found very unique  Genes  sequence causing the respiratory illness in human. Only 14% of the individuals have been reported with severe form of illness like respiratory failure, hypoxia. According to researches, virus first orig

Cloning is a biological term used to make multiple copies of a particular organism by using the asexual method. Cloning can be of different types including bacterial cloning, fission, etc. We can use the process to make multiple copies of a particular gene by using a particular vector i.e., E.coli. The most commonly used biological vectors are plasmids (extrachromosomal structures in bacteria).                                        The first animal was cloned by splitting embryos in a test tube and the resulting embryos were transferred to the womb of adult female mice. Following that, biologists produced several other animals including cows, sheep, cattle, horses, mules, ox, etc. The nucleus can be transferred to the recipient organism by using two methods. One of the methods involves the removal of the nucleus by injecting a needle and transferring it to another cell. The second method involves the use of electric current to transfer the nucleus from a somatic cell to another empti

Polymerase Chain Reaction Within the domain of atomic science, Polymerase Chain Response (PCR) stands as a foundation, revolutionizing the way researchers analyze and open up DNA. PCR, a capable method created by Kary Mullis in 1983, has gotten to be an crucial device in different logical disciplines, extending from hereditary qualities and forensics to restorative diagnostics. Understanding the Essentials of PCR: PCR could be a strategy utilized to exponentially increase a particular portion of DNA, permitting analysts to produce millions of duplicates from a little beginning test. This handle includes three primary steps: denaturation, strengthening, and expansion. Amid denaturation, the DNA twofold helix is isolated into two single strands. Within the strengthening step, preliminaries tie to the focused on DNA grouping, and at long last, DNA polymerase synthesizes complementary strands amid the expansion stage. Applications of PCR in Medication: PCR has revolutionized restorative di
