NEETBotanyBiological Classification
Description Characteristic A. Contains single or double-stranded RNA or DNA 1. Protein coat made of capsomeres B. Can be crystallized and consist largely of proteins 2. Non-cellular and obligate parasite C. Protein coat arranged in helical or polyhedral forms 3. Genetic material that could be RNA or DNA D. Can infect plants and cause symptoms like mosaic formation 4. Can cause diseases such as AIDS, mumps, and influe
Options
- AA - 2, B - 3, C - 4, D - 1
- BA - 1, B - 3, C - 2, D - 4
- CA - 3, B - 2, C - 1, D - 4
- DA - 4, B - 2, C - 1, D - 3
Correct answer
C. A - 3, B - 2, C - 1, D - 4
Step-by-step solution
A - 3: Viruses contain either single or double-stranded RNA or DNA, but not both. B - 2: Viruses can be crystallized, and their crystals consist largely of proteins, reflecting their non-cellular and obligate parasitic nature. C - 1: The protein coat of viruses, known as the capsid, is made of capsomeres and can be arranged in helical or polyhedral geometric forms. D - 4: Viruses can infect plants and cause various symptoms, including mosaic formation, leaf rolling, and stunted growth, and they also cause diseases
