දැනුවත් තලාට සිතුතියි යාඑවා
එ ත් බං මට තියන ප්රශ්ණය මෙචචර ශරිරය ගැන දන්න විද්වත්තුට මෙකට හරිහමන් විසදුමක් දෙන්න ලොකයේ මොනජගතේ කුටවත් බැරි උනා ඉතින් බං මුන් තාක්ශනේන් අගහරු ගියින් වැඩක් තියෙනවාද මිනිස් ජිවිත වලට වෙන විපත් මගහරවා ගන්න බැරිව
It's not easy to design an anti-viral. These are made to trick the virus, thus blocking one or more of the steps it needs to replicate or infect host cells. Different drugs work by using different mechanisms. Also these drugs must
not cause any harm to our cells. Viruses have polymerases that keep on adding nucleotides which are sort of like building blocks. A drug might present itself like one of these blocks, the viral polymerase grabs it thinking that its another building block but that's a decoy, not real. No more further blocks can be added. Then the virus is kaput.
It's not easy to explain in brief but it's not an easy job to develop a drug. May be will write on this another time.
As I mentioned earlier there are DNA vaccines already developed to cut the Covid virus precisely, but it will take at least two more years to get approval, as these have never, ever been used on humans.
As you say, a mission to Mars could be easier. It's the same "Engineering" here and there.
