Which of the following are situated in the nucleus of a cell?

Chromosome and genes

The correct answer is Option (1)- Chromosome and genes

Chromosome and genes are situated in the nucleus of a cell.

Explanation:

The nucleus is a membrane-bound organelle that contains genetic material in the form of chromosomes. Chromosomes consist of DNA, which carries genes—the functional units of heredity. Genes are specific segments of DNA that code for the synthesis of proteins and play a crucial role in determining an organism's traits.

The other options do not accurately represent components located in the nucleus:

• Cytoplasm and chromosome: The cytoplasm is the gel-like substance surrounding the nucleus, and chromosomes are within the nucleus.
• Nucleolus and cytoplasm: The nucleolus is a structure within the nucleus, not in the cytoplasm.
• Protoplasm and chromosome: Protoplasm refers to the entire living content of a cell, encompassing the cytoplasm and nucleus. Chromosomes are specifically found within the nucleus.
