Animal "pharming" is becoming more popular as the demand for human proteins and vaccines continues to grow. Animal "pharming" is the process of using transgenic
animals to produce human drugs such as insulin and human growth hormone.
Transgenic animals are animals which have been genetically transformed by splicing
and inserting foreign genes into their chromosomes. If successful, the inserted gene
can enable an animal to make certain proteins in its milk, blood, sperm, or eggs. Which
of the following is NOT true about transgenic animals?

O Transgene DNA may insert itself into the genome in a way that disrupts the animal's normal
gene function

O Transgenic animals cannot pass their ability to produce desired drug to its offspring

O Transgenic animals can produce the desired drug at high levels without endangering its own
health
Transgenic animals can be easily tested for the new gene

Operons can be used to coordinate the expression of multiple proteins in combination in the prokaryotes. An operon is a fundamental unit of DNA that transcribes, translates, or splices an array of genes under the guidance of a single operator and promoter.  

The expression of genes can take place in combination or not at all. The regulation of operon can either be positive or negative due to repression or induction.
