Correct Option (b)
Explanation
Statement 1 is incorrect.
- Adenoviruses are characterized by double-stranded DNA (dsDNA) genomes.
- Retroviruses, such as the Human Immunodeficiency Virus (HIV), possess single-stranded RNA (ssRNA) genomes. They utilize reverse transcriptase to synthesize a double-stranded DNA (dsDNA) intermediate, which is then integrated into the host genome during their replication cycle.
- Therefore, the description of genome types for both viruses in statement 1 is inaccurate.
Statement 2 is correct.
- Adenoviruses are a group of viruses known to cause various illnesses, including respiratory infections such as the common cold.
- Acquired Immunodeficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV), which belongs to the retrovirus family.
Incorrect Options
- Option (a) is incorrect because statement 1 contains factual inaccuracies regarding the genome types of adenoviruses and retroviruses.
- Option (c) is incorrect because although statement 2 is correct, statement 1 is incorrect.
- Option (d) is incorrect because statement 2 is factually correct, rendering the option "Neither 1 nor 2" invalid.
