You have designed a drug that irreversibly binds to the p-site of the ribosome. what is the outcome for a growing bacterial cell
Sonja [21]
<span>The P-site of the ribosomes is the site of polypeptide elongation during translation of mRNA. Therefore, a drug that binds to this site ensures that there is no elongation hence, basically, the translation process is inhibited. The <span>growing bacteria cell will stop growing and die due to lack of structural and functional proteins to grow and perform its cellular processes respectively..</span></span>

Which microscope would be used to observe surface structure of corona virus?
ElenaW [278]

Answer:

SEM ANSWER

Explanation:

Electron microscopy is a powerful tool in the field of microbiology. It has played a key role in the rapid diagnosis of viruses in patient samples and has contributed significantly to the clarification of virus structure and function, helping to guide the public health response to emerging viral infections. In the present study, we used scanning electron microscopy (SEM) to study the infectious cycle of SARS-CoV-2 in Vero E6 cells and we controlled some key findings by classical transmission electronic microscopy (TEM). The replication cycle of the virus was followed from 1 to 36 h post-infection. Our results revealed that SARS-CoV-2 infected the cells through membrane fusion. Particles are formed in the peri-nuclear region from a budding of the endoplasmic reticulum-Golgi apparatus complex into morphogenesis matrix vesicae. New SARS-CoV-2 particles were expelled from the cells, through cell lysis or by fusion of virus containing vacuoles with the cell plasma membrane. Overall, this cycle is highly comparable to that of SARS-CoV. By providing a detailed and complete SARS-CoV-2 infectious cycle, SEM proves to be a very rapid and efficient tool compared to classical TEM.
