The spherical DNA-containing structure of the cell body is the ...

• A. Cytoplasm
• B. Nucleus
• C. Dendrites
• D. Neuron

Answer: (B)

In cells, the genome is housed in the nucleus, a membrane-bound, typically spherical organelle. In neurons, the cell body (soma) contains this nucleus, which stores DNA and coordinates gene expression. The cytoplasm surrounds the nucleus and contains various organelles where metabolism happens, but the genome isn’t stored there. Dendrites are neural extensions for receiving signals, and a neuron refers to the entire cell, not a specific compartment. So the spherical DNA-containing structure in the cell body is the nucleus.
