Why in dna copying mechanism creates variation.
Answers
DNA copying mechanism is extremely necessary for reproduction as copying of DNA helps in transfer of information or characters from parents to offspring. It also generates variations during sexual reproduction. This variation leads to evolution. ... Each cell then receives an equal number of the chromosomes or DNA.
variations arise during the process of reproduction.
A basic event in reproduction is the creation of DNA copying. DNA copying is accompanied by a cell division giving rise to two cells.
The minor variations arising during sexual reproduction is caused by crossing over the process of meiosis. whereas in asexual reproduction it is caused by slight inaccuracies in DNA copying.
These variations help the species to survive better in the environment and also leads to evolution.
