What is the importance of DNA copying in reproduction?

Solution: DNA is a vital macromolecule essential for life hence commonly called the blueprint of life as it contains all the information determining body structure and design of an organism.

DNA is transferred from parents to offsprings; equally from both mother and father this results in inheritance of characters. As we share DNA with our parents we resemble their characteristics. 

DNA replication is the process of synthesising two new DNA molecules using a single parent DNA molecule and this is important during gamete formation to segregate the DNA equally. 

DNA copying/ DNA replication: 

  • DNA copying of DNA replication refers to the process of new DNA synthesis by using parent DNA as template during cell division. 

  • It is an important step in the transfer of genes from parents to offspring.

  • DNA inheritance is a key factor maintaining the existence of particular species

  • DNA replication is specifically important in the organisms that reproduce asexually. 

  • In such organisms, only a single parent determines the characteristics of progeny hence there is no variation in traits

  • While in case of sexual reproduction both the parents replicate their DNA and contribute single copy of DNA where both the genetic materials can undergo recombination and a set of totally deffent combination can arise in progeny. 

  • DNA acts as a characteristic determining factor and gets inherited from parents to offspring through gametes. For this DNA first has to be replicated into multiple copies hence DNA replication is very essential during reproduction
