The mismatch of a dna base pair during duplication can result in a mutation.
true
false

The answer is true. Mutation is the result of the mismatch of a base pair during the duplication. Mutations are neither the results from errors during the replication of DNA or other types of damage to DNA. In simpler words, DNA errs to copy accurately.

If cells from a carrot are removed and placed in a culture medium, they can develop into a normal adult plant. This demonstrates that carrot cells retain all the genes that were in the zygote that developed into the original plant.  

It is known that carrot has callus stem cells-a mass of undifferentiated plant cells that can be re-differentiated into the specialized tissues of a whole plant. This ability is known as “totipotency” and the carrot callus stem cell is recommended for moisturizing application.
