Why lysosomes and vacuoles don't have DNA
Answers
1.DNA is deoxyribonucleic acid. All the 23 pair chromosomes carry DNA. These are double-stranded coiled helices. These have two polypeptide strands. DNA is deoxyribonucleic acid. It is composed of two polynucleotide chains.
2. They coil around each other forming a helix. It carries information about the genetic development, growth, and functioning of an individual. These also carry the physical trait genes from the parents. A DNA molecule has a sugar, phosphate, and purine/pyrimidine group.
3.It is usually present in the nucleus of the cell as it is the center of genetic information. Other than the nucleus, the mitochondria and chloroplast have their DNA.
4.The lysosome is the membrane organelles, formed from the Golgi apparatus. Their major function is to remove the waste from the cell. The autolysis is the process of destruction of a cell which is carried out by the lysosome.
5.Thus the enzymes like DNase, Rnase, protease, etc. are present in them to digest the macromolecules and nucleic acids. The vacuole is a bubbles-like structure, found in animal and plant cells, which store the food or nutrients.
6.They can also have waste products to protect the cell from contamination. There are a larger number of vacuoles in a cell. Their main function is to store nutrients and food.
