A molecule that can act as a genetic material must NOT fulfill which of the the traits given below?
Correct answer: C. It should be unstable structurally and chemically
- A. It should be able to express itself in the form of 'Mendelian characters'
- B. It should be able to generate its replica
- C. It should be unstable structurally and chemically
- D. It should provide the scope for slow changes that are required for evolution
Explanation
Genetic material should be structurally and chemically stable otherwise its expression will change. This will lead to a loss of several metabolic functions, etc. The genetic material in any living organism consists of the fundamental information required to carry out various life processes related to development, growth, metabolism, reproduction, etc. DNA (deoxyribose nucleic acid) and RNA (ribonucleic acid) are known to constitute the genetic material in all organisms. The genetic material is stabilized using various interactions like van der Waals forces, hydrophobic interactions, and hydrogen bonds. The structural and chemical instability of the genetic material will result in impairment of cell function, mutations, and transformation to cancerous cells, or diseases.

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.
