The caps and tails attached to mRNA protect it from:
Correct answer: C. Nucleases and phosphatases
- A. None
- B. Ligases
- C. Nucleases and phosphatases
- D. Polymerases
Explanation
Nucleases are enzymes that degrade nucleic acids, while phosphatases remove phosphate groups from molecules. The caps and tails on mRNA protect it from nucleases and phosphatases by providing structural stability and preventing enzymatic degradation. This protection ensures that the mRNA remains intact for longer periods, allowing it to carry out its functions such as translation into proteins.

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.
