What is the importance of DNA replication to all living organisms? What is the importance of DNA replication to all living organisms?
DNA replication removes harmful traits from an organism.
DNA replication passes on traits from parents to offspring.
DNA replication ensures that gametes have unique genes.
DNA replication determines which genes are active.
The correct answer is option B, DNA replication passes on traits from parents to offspring.
DNA replication is essential to carry genetic traits from parents to the new offsprings. There are two strands in each parental DNA which gets separate and they then serve as template for the synthesis of new daughter strand by using complementary base pairing. This is known as semiconservative replication as the one strand of parental DNA is conserved
B.DNA replication passes on characters from parents to offsprings
