Question

question 1 (2.5 points)
eukaryotic cells have their dna enclosed in the
plasma membrane
nucleus
nucleoid
nuclear envelope
nucleotide

Explanation:

Eukaryotic cells have a true nucleus. The nucleus is a membrane - bound organelle that encloses the cell's DNA. The plasma membrane is the outer boundary of the cell, not where DNA is enclosed. The nucleoid is found in prokaryotic cells (no true nucleus). The nuclear envelope is the double - membrane of the nucleus but the structure that encloses DNA is the nucleus. A nucleotide is a building block of nucleic acids (like DNA), not a structure that encloses DNA.

Answer:

nucleus
