crop improvement.
human proteins.
question 13 (1 point) ✓ saved
________ are the primary sources of most antibiotics.
bacteria and viruses
viruses and protistans
protistans and fungi
fungi and bacteria

Explanation:

For Question 11: Gene expression first involves transcription (DNA to RNA), then translation (RNA to protein). So the statement "Translation is the first stage of gene expression" is false.
For Question 12: Transgenic animals have had foreign genes inserted into their genomes. They can be engineered to produce human proteins (e.g., some transgenic goats produce human antithrombin).
For Question 13: Many antibiotics are derived from fungi (e.g., penicillin from Penicillium) and bacteria (e.g., streptomycin from Streptomyces).

Answer:

Question 11: B. False
Question 12: D. human proteins
Question 13: D. Fungi and bacteria
