Question

a. Briefly discuss how mutations to DNA can occur and what the effects mutations may
cause.
A permanent change in the DNA sequence occurs. While this happens the mutations
alters the amino acid sequence. The process is a permanent change in the DNA
sequence of a gene. Mutations in a gene's DNA sequence will alter the amino acid
sequences of the protein which is encoded by the gene.
b. Are mutations good, bad, both or neutral, from a biological perspective? Explain
your answer. Research your answer and provide internal citations and a reference page
in proper APA format.
Mutation is very tricky. On one hand, mutation is necessary to introduce variation into
the gene pool of a population. Genetic variation has been shown to correlate with
species fitness. On the other hand, most mutations are deleterious to the individuals in
which they occur. So mutation is good for the population, but generally not so good for
the individual. Some mutations arise as natural errors in DNA replication. Mutations can
also be caused by agents in the environment. Mutations can affect individuals in a
variety of ways. Change in a morphological trait. Nutritional, biochemical variation.
Change in behavior, changes in gene regulation, even lethality.
c. Compare and contrast the processes of replication and transcription (copy/pastes the
table into your document).
