What is DNA copying? State importance of DNA copying in reproduction.

@Amit: Apart from the answer provided by your friend. I would like to add that 

DNA copying mechanism is extremely necessary for reproduction as copying of DNA also generates variations during sexual reproduction. This variation leads to evolution. DNA copying is also necessary because DNA (Deoxyribonucleic acid) is the genetic material found in the chromosomes, which are present in the nucleus of a cell. The DNA is the information site for making proteins and each specific type of protein leads to a specific type of body design and if DNA is not copied properly then offspring might face some serious abnormalities or might not even develop.

@Naren: Good work! Keep it up.

DNA copying is a biological process that occurs in all living organisms and copies their DNA it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle also pertains to the DNA replication/reproduction process. The cell cycle includes, interphase, prophase, metaphase, anaphase, and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand, a process referred to as semiconservative replication. Cellular proofreading and error toe-checking mechanisms ensure near perfect fidelity for DNA replication.


DNA replication is an important process that ensure that when cell multiplies, through the mechanisms of mitosis and meiosis, the equal amount of DNA (genetic material) passes in to the new cell. The DNA replicates so that there will be an extra DNA when the cell multiplies, allowing the "daughters" the chance to reproduce.

hope this helps you frnd..........
