A giant chromosome with a number of chromonemeta is ________ ?
Correct answer: D. Polytene chromosome
- A. Lampbrush chromosome
- B. Hetero chromosome
- C. Supernumerary chromosome
- D. Polytene chromosome
Explanation
A polytene chromosome is a giant chromosome formed by repeated DNA replication without cell division, producing many aligned chromonemata or chromatids. Students may choose a lampbrush chromosome because it is also unusually large, but lampbrush chromosomes have extended loops and are not characterized by numerous parallel chromonemata in the same way.

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.
