Step 1
Step 2
B. Human growth hormone can cause E. coli to grow and mature rapidly.
Answer
This statement is misleading. While the human growth hormone can be produced in E. coli, it does not directly affect the growth rate of E. coli itself. The role of the hormone is rather in the production of desired proteins.
Step 3
C. Human plasmids containing the gene of interest can be inserted into bacteria.
Answer
This statement is accurate. In biotechnology, human genes can be inserted into plasmids, which are then introduced into bacteria like E. coli. This allows for the production of human proteins, such as growth hormone.
Step 4
D. Restriction enzymes can produce sticky ends on both bacterial and human DNA.
Answer
This statement is correct. Restriction enzymes cut DNA at specific sequences, creating sticky ends that facilitate the insertion of genes into plasmids, which can then be introduced into bacteria for protein expression.
