Difference between infectivity and cell fusion abillity of Virus. (COVID 19)

I’m a computational chemist who have interest in COVID-19. As a physical chemist, I’m lack of basic knowledge for biology. What is the difference between ‘infectivity’ and ‘membrane fusion activity’? I thought that, for corona virus, infection is equal to membrane(cell) fusion, but it seems wrong idea. Thank you for reading!

I need to write an essay about a protein. I chose Keratin. But I need to write about its structure

But to do that I need the primary, secondary and tertiary and lastly the qua ternary structure as I need to link it back to the function. Do you know what these structures are in primary to qua ternary?

Do plant cells recycle carbon dioxide from their respiration during photosynthesis?

It seems one of my colleague’s biology textbook claims that plant cells, with presence of light, feed back 100% of carbon dioxide molecules from their respiration into photosynthesis. Is there any evidence that carbon dioxide, gas or dissolved, transferred from the mitochondria to the chloroplast?

Identify this gray spider with distinctive white mark

I was out back in the garden tonight and found an extremely long strand of web running about 10 ft. At the end was a kind of spider I’ve never seen before. It’s about a .75-1 inch, fat body, with a distinctive white mark on its back. It was very docile while I took the […]

I just sequenced my whole genome, can someone tell me what are these different file formats?

I just sequenced my whole genome and now I want to play a bit with bio-informatics. However, the documentation is quite scarce on the file standards used… These are the files I have been given (the “raw” data): Can someone explain me with some detail what is each file format, and for what are they […]

How the duplication of bacteriophage happen in Lysogenic infection?

I was watching a video and the teacher said that a virus go from lytic to Lysogenic cicle. He kept saying that the virus genetic material duplicates with the host cell he never said “duplicate with the bacteria”. In Lysogenic infection, considering the fact that bacterias are unicellular, when the virus genetic material duplicate with […]

Single Cell RNA sequencing downstream functional study?

During this lock down time I read through few single cell RNA sequencing papers and find that all the papers are analysis heavy. Rarely any downstream functional study of their finding. So, I was just thinking how a molecular biologist/ model organism biologist can contribute to this study in strengthening the findings. I did not […]
