Extremely long molecule of DNA that is tightly folded to fit inside the cell component is called?
Correct answer: B. Chromosome
- A. Nucleus
- B. Chromosome
- C. Chromatin body
- D. Chromatid
Explanation
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

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.
