Answer:
each new cell needs a DNA copy, which serves as instructions on how to function as a cell. DNA replicates before a cell divides. The replication process is semi-conservative, which means that when DNA creates a copy, half of the old strand is retained in the new strand to reduce the number of copy errors.

<u>Evolution is sometimes a controversial:</u>
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
