Each cell of the human body contains 46 chromosomes. How many DNA molecules does this statement represent? How many different types of DNA molecules does it represent?
Shown below is a DNA coding strand. A base (*G*) mutates to Adenine (A). What will be the resulting amino acid sequence as a result of the mutation? What type of mutation occured?
Hint: Determine the template, then first determine the amino acid sequence before the mutation, and then determine the amino acid sequence after the mutation. Show how you got your answer.

She is planning on working with the nucleus of a human and the nucleus of a mouse. She has removed all of the DNA from each nucleus, then has selected and isolated one DNA fragment from each species. What results can Neema expect if she takes the human DNA fragment and inserts it into the mouse nucleus and then inserts the mouse DNA fragment into the human nucleus? Use your knowledge of DNA replication to answer.arrow_forward
