Use the chart below to answer the following quesThe use of genetically modified animals has been important in medical research. Transgenic animals are routinely bred to carry human genes. At times these animals are given mutations in specific genes. This allows researchers to study the progression of various illnesses and diseases. Biomedical researchers often use transgenic mice as they are “small” models for their study. Transgenic mice express the foreign gene that was deliberately inserted into its genome (DNA). Which of the following facts best explain how transgenic mice are possible?

Viral DNA is encoded into the host DNA during the lysogenic process.

The use of sequenced nitrogen bases as genetic code is in all living things.

Protein synthesis does not occur in all organisms.

Meiosis reproduces new gametes. tion.
