Answer:
Use of a drug selection eliminates those stem cells with nonhomologous recombination products. (mouse)
Viral vectors, microinjection, T-DNA, electroporation, and biolistic transfer. (fruits and veggies)

Created using constituitively expressed DNA from genetically unrelated species. (fish)
^^^ ANSWERS ARE IN PARENTHESES ^^^
Answer:
C. External fertilization is common for animals that live in water.
Explanation:
Answer:
Since there are many factors that can produce a mutation, the event that would be most likely to cause a mutation is a nucleotide is inserted into a DNA strand.
Explanation:
A genetic mutation involves an alteration of the DNA that leads to a defect in protein synthesis and a structural or functional alteration of an individual.
Of all the factors that can produce a mutation, the insertion of one or two nucleotides into the DNA strand produces a point mutation, or molecular mutation, of the insertion type.
<em> The other options are not correct because the processes of </em><em><u>mRNA traveling out of the nucleus</u></em><em>, </em><em><u>mRNA releasing from the DNA strand</u></em><em> or </em><em><u>enzymatic transcription of mRNA</u></em><em> in the nucleus can carry over a mutation produced in the DNA, but they are not mutation-producing factors.</em>
