What characteristic is NOT associated with eukaryotic cells?

What characteristic is NOT associated with eukaryotic cells?

• A. Presence of a nucleus
• B. Complex structure with membrane-bound organelles
• C. Lack of DNA bound in histones
• D. Cellulose in plant cell walls

Answer: (C)

Eukaryotic cells are defined by several distinguishing features, one of which is the presence of a well-defined nucleus that contains the cell’s genetic material. Additionally, these cells have a complex structure that includes various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, all functioning in a coordinated manner to support cellular processes. Plant cells, which are a subset of eukaryotic cells, also contain cellulose in their cell walls, providing structural support and protection. The statement about the lack of DNA bound in histones is incorrect regarding eukaryotic cells, as their DNA is indeed associated with histones. These proteins help to package and organize the DNA into a structure called chromatin, which allows for efficient gene regulation and arrangement during cell division. Hence, the presence of histone-bound DNA is a characteristic feature of eukaryotic cells, further underscoring that the correct choice accurately highlights a feature not associated with eukaryotic cells.
