Which one of the following statements about the particular entity is true?
Correct answer: B. The gene for producing insulin is present in every body cell
- A. The centromere is found in animal cells, which produces an aster during cell division
- B. The gene for producing insulin is present in every body cell
- C. The nucleosome is formed from nucleotides
- D. DNA consists of a core of eight histones
Explanation
The Insulin gene is found in every body cell but is not expressed in all cells. A nucleosome consists of a core of eight histones. DNA is composed of nucleotides. Centrioles are found in animal cells, which produce asters during cell division.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
