If the envelope of a particular virus were unstable outside the host’s body, which of the following statements would you expect to be true concerning this virus?

a. It would be a dsRNA virus.
b. It would be transmitted by intimate contact.
c. Touching a doorknob would easily transmit it.
d. That virus would eventually cease to be a threat to the population.

Expert Solution & Answer

Summary Introduction

Introduction:

The viral envelop is derived from the outer membrane of the virus body and it confers the sensitivity of the virus against detergent, heat, dryness, and alcohol. Virus without envelop is more resistant against harsh condition as compared to the enveloped virus.

Answer to Problem 1MC

Correct answer:

Virus which contains an unstable envelope outside the host’s body is transmitted by intimate contact. Therefore, option (b) is correct.

Option (b) is given as “it would be transmitted by intimate contact”.

Explanation of Solution

Justify reason for the correct statement:

Enveloped viruses have protein capsid and lipid bilayer which make them more sensitive towards environment condition. Thus, they need an intimate contact such as body fluid between their hosts in order to get transmitted.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “It would be a dsRNA virus”.

Most of the dsRNA virus are naked virus which do not contain envelop. Hence, it is a wrong answer.

Option (c) is given as “Touching a doorknob would easily transmit it”.

Enveloped virus can only get transmitted by an intimate contact between the hosts. Hence, it is a wrong answer.

Option (d) is given as “That virus would eventually cease to be a threat to the population”

Naked virus such as Variola virus is more contagious and thus, they would cease to be a threat to the population. Hence, it is a wrong answer.

Hence, options (a), (c) and (d) are incorrect.

Conclusion

Enveloped virus are more sensitive against the environmental condition, hence they need an intimate contact between their hosts for transmission.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
