Which one of the following hydrolyses internal phosphodiester bonds in a polynucleotide chain?
Correct answer: C. Endonuclease
- A. Lipase
- B. Protease
- C. Endonuclease
- D. Exonuclease
Explanation
The answer is endonuclease. Endonucleases are enzymes that hydrolyze internal phosphodiester bonds in a polynucleotide chain. They are used in many different cellular processes, such as DNA replication, DNA repair, and gene expression.The other options are incorrect because :Lipase hydrolyzes triglycerides into fatty acids and glycerol.Protease hydrolyzes proteins into peptides and amino acids.Exonuclease hydrolyzes phosphodiester bonds at the ends of a polynucleotide chain.

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.
