Question

What is the importance of DNA copying in reproduction? Explain with an example.

Solution

DNA copying refers to the replication of DNA at the time of cell division. It plays a very important role in giving rise to slight variations in offsprings in comparison to the parents particularly in asexual reproduction where only single parent is involved.
Example: When a cell divides, the DNA of the cell gets replicated first so that the daughter cells get equal amount of DNA from the parent. DNA replication occurs through biochemical process which is not accurate. Hence, variations are introduced in the DNA during replication. When the cell divides, the daughter cells acquire a slightly different DNA to that of the parent. Therefore, the DNA of the daughter cell is similar to that of the parent but not identical.

  Is there an error in this question or solution?
