Question

multiple choice 10 points
which is a step in the process of producing transgenic bacteria to make human insulin?
a chain of bacterial amino acids is inserted into human dna.
a plasmid is used to replace a faulty gene in a human cell.
a mutation is produced in a bacterial cell
a human gene is inserted into a bacterial plasmid.
multiple choice 10 points
which of the following technologies best describes the process of replacing a defective gene with a functioning gene using genetic engineering?
stem cell research
cloning
gene therapy
gel electrophoresis

Explanation:

For question 7, in producing transgenic bacteria for human insulin, a human gene (for insulin - production) is inserted into a bacterial plasmid. This allows bacteria to produce human insulin. For question 8, gene therapy is the process of replacing a defective gene with a functioning gene using genetic - engineering techniques. Stem cell research is about undifferentiated cells, cloning is about creating identical organisms or cells, and gel electrophoresis is for separating DNA fragments.

Answer:

1. D. A human gene is inserted into a bacterial plasmid.
2. C. gene therapy
