You conducted an experiment to determine the mechanism of DNA replication in the hypothetical organism Fungus mungus. Your data shows that synthesis of newly replicated DNA from F. mungus is discontinuous on both strands of the replication fork. Does this result support or not support the hypothesis that F. mungus replicates its DNA by the same mechanism as yeast?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
