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.

Please read the scenario below and then answer the question (in bold) that follows. An original DNA sequence reads 3'- GGCGCTAGAATC -5'. A mutated version of that DNA strand is produced that reads 3-GGCTCTAGAATC -5. Based on the information above, how severe of an impact do you believe the mutation would have on the cell (and therefore individual) in which the mutation occurred? O a. Very severe, because the mutation leads to the formation of a truncated polypeptide O b. Moderately to very severe, because the mutation results in the formation of a polypeptide that contains amino acids not found in the unmutated polypeptide O c. Likely not that severe, because the amino acid sequence of the mutated polypeptide is identical to the amino acid sequence of the nonmutated polypeptide
