DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.
Explanation:
Mutation is the process
It is caused by certain chemicals called mutagens or by environmental factors.
In mutation the nucleotide get change which eventually changes the protein product.
In mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.
A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.
In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.

The answer is h It can be split into thin, flat layers. This foliated rock slate is made up of parallel plates, giving it the ability to break into smooth, even and thin layers which are along its cleavage. This characteristic makes slate most suitable for roofing shingles, flooring and flagging.
