Consider the following statements with reference to viruses:1. These a...
- A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material (but no virus can have both). The nucleic acid may be single- or double- stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins. The most complex can encode 100 - 200 proteins. Hence statement 1 is correct.
- Viruses can cause both Viral hemorrhagic fevers (VHFs) and cancers. When viruses cause an infection, they spread their DNA, affecting healthy cells' genetic makeup and potentially causing them to turn into cancer. HPV (Human Papillomavirus) infections, for instance, cause the virus’ DNA to combine with the host’s DNA, disrupting the normal function of cells. Hence statement 2 is correct.

Understanding Viruses: Key Statements Explained
Viruses are fascinating entities that play significant roles in various biological processes and diseases. Let's analyze the statements provided:
Statement 1: Microscopic Parasites
- Viruses are indeed microscopic and can be classified as parasites because they rely on a host cell to replicate.
- They contain either RNA or DNA as their genetic material, distinguishing them from other microorganisms.
Statement 2: Viruses and Disease
- Viruses are known to cause a range of diseases, including hemorrhagic fevers (e.g., Ebola virus) and certain types of cancers (e.g., Human Papillomavirus leading to cervical cancer).
- This statement is accurate as it reflects the diverse pathogenic potential of viruses.
Statement 3: Antiviral Treatment
- Antiviral medications do work by inhibiting the multiplication of viruses in the host.
- However, most antivirals do not kill the viruses directly; instead, they inhibit their replication and spread, allowing the immune system to eliminate the infection.
Conclusion: Correctness of Statements
- Statements 1 and 2 are correct.
- Statement 3 is partially correct; while antivirals inhibit viral replication, they do not necessarily kill the viruses outright.
Thus, the correct answer is option B (1 and 2 only). This option accurately reflects the nature of viruses and their treatment.
