Concept explainers
(1)
To determine:
The reasons that government can cite for maintaining smallpox viruses.
Concept introduction:
The United States and Russia have repeatedly agreed to destroy their stocks of the smallpox virus, but the deadline has been put off many times. In the meantime, the entire genome of variola virus has been sequenced. Smallpox is an infectious disease of the past that was eliminated worldwide by vaccination. Affected people become ill with high fever and rashes.
(2)
To determine:
Whether laboratory stores of smallpox viruses should be destroyed.
Concept introduction:
The United States and Russia have repeatedly agreed to destroy their stocks of the smallpox virus, but the deadline has been put off many times. In the meantime, the entire genome of variola virus has been sequenced. Smallpox is an infectious disease of the past that was eliminated worldwide by vaccination. Affected people become ill with high fever and rashes.
(3)
To determine:
Weather elimination of all laboratories stock really be the extinction of smallpox virus.

- What is the virus transmission, morphology, and the family name for the virus that causes smallpox?arrow_forwardAccording to the article which was written before the COVID-19 vaccine was created, when do people turn to magic? How can this tendency, which happens across cultures and throughout history, contribute to the current spread of the novel coronavirus and its variants?arrow_forwardWill it be possible to eradicate many viral diseases in the same way as smallpox? Why or why not?arrow_forward
- What factors inherent in the variola virus and the disease smallpox made it possible to eradicate them?arrow_forwardAs a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.arrow_forwardWhat if the vaccine for covid 19 contains nanotechnology to fight the virus?arrow_forward
- Arrange the following list into the correct sequence for part of the cycle of a retrovirus: 1. dsDNA integrated into host DNA 2.viral proteins synthesized on host ribosomes 3. viral DNA uses host enzymes to transcribe viral RNA 4. reverse transcriptase catalyzes synthesis of ssDNA 5. synthesis of second DNA strand (a) 5, 2, 1, 3, 4 (b) 5, 2, 3, 4, 1 (c) 4, 5, 1, 3, 2 (d) 4, 1, 2, 3, 5 (e) 2, 1, 3, 4, 5arrow_forwardwhat is N1H1 virus ? explain in the pharagraph form, please?arrow_forwardWhich of the following statements concerning antigenic drift in influenza viruses is correct? A-It results in major antigenic changes B-It affects predominantly the matrix protein C-It is exhibited by only influenza A viruses D-It is due to frame shift mutations in viral genes E-It results in new sub types over timearrow_forward
- explain what the arguments are for keeping or destroying the smallpox virus? Which do you agree with and why?arrow_forward. Rotavirus, a disease-causing member of the Reovirus family (with double-stranded RNA, but no DNA), must use which of the following enzymes to replicate its nucleic acid? RNA-dependent-RNA-polymerase RNA-dependent-DNA-polymerase DNA-dependent-RNA-polymerase DNA-dependent-DNA-polymerase reverse transcriptasearrow_forwardWhat is the etymology (origin) of the word "vaccine"?arrow_forward
