Question

Which of the following are applications of genetic engineering? Check all that apply.

identifying types of cancer

creating vaccines to prevent illness

identifying the type of microorganism causing an infection

producing hormones to treat certain diseases

have made many serious illnesses, such as polio, rare. They were initially made with
weakened
, but modern biotechnology has expanded methods of development to prevent more diseases.

Answer 1

All four are applications of genetic engineering:

- identifying types of cancer — yes (genetic/molecular profiling)
- creating vaccines to prevent illness — yes (recombinant, mRNA, subunit vaccines)
- identifying the type of microorganism causing an infection — yes (PCR, sequencing, molecular diagnostics)
- producing hormones to treat certain diseases — yes (recombinant insulin, growth hormone, etc.)

Complete sentence:
"Vaccines have made many serious illnesses, such as polio, rare. They were initially made with weakened (attenuated) or killed pathogens/viruses, but modern biotechnology has expanded methods of development to prevent more diseases."
