How mutations to DNA can occur and what the effects mutations may cause.




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).;PROCESS;WHEN;does it;occur?;WHERE in;the cell;does it;occur?;WHAT;exactly is;happening;during the;process?;What;NUCLEOTIDE;BASES are;involved?;DNA;Replication;Transcriptio;n;d.
