rna is found in cells, but not in viruses.
viruses can infect certain cells.

Explanation:

• Analyze each option:
• Option 1: Viruses don't grow and reproduce like cells (they need host cells to replicate), so this is incorrect.
• Option 2: Cells don't infect viruses; viruses infect cells, so this is incorrect.
• Option 3: Many viruses (like RNA viruses) contain RNA, so this is incorrect.
• Option 4: Viruses are obligate parasites and can infect specific (certain) host cells, which is correct.

Answer:

D. Viruses can infect certain cells (assuming the options are labeled A - D with D being the last option as per the list: A. Viruses grow and reproduce like cells, B. Cells can infect specific host viruses, C. RNA is found in cells, but not in viruses, D. Viruses can infect certain cells)
