If DNA is not copied during reproduction , correct proteins will not be formed and the structure and functions of the individual will be entirely different.

It transfer genetic charecter from parents to progny
but knowledge is most importance for us…
It is not our level types questions

To carry out the characters from patent to offsprings
DNA cause variations among organism

DNA copying is an essential step in reproduction,as it helps to transmit genetic information from parents to offspring.Sometimes, DNA copyingintroduces minute changes in DNA sequence,which lead to variation,and progressively evolution.

DNA-(deoxyibose nucleic acids) DNA copying leads to the formation of two exactly identical cell but any error in duplication can lead to dissimulation cells of variations
The copying of DNA during reproduction is important because:\tThe replication of DNA ensures that each daughter cell formed at the end of cell division, receives equal amount of DNA.\tIf DNA won\’t be copied then the daughter cells won\’t receive all necessary genes.\tThere may be absence of important proteins which are encoded by DNA, if DNA won\’t be replicated.\tCopying of DNA may result in recombination which will lead to evolution.\tTransfer of genetic material from one generation to other makes the organisms to have similar functions.\tStability of population is maintained.
DNA ? copying is important during reproduction because it leads to the transmission of characters from parents to the offsprings and bring about variations. Hope it helped you….. Thanks, Regards
