Question

Indicate whether the following statements about DNA technology in medicine are true or false.


DNA technology is used to identify hereditary diseases.

DNA technology is used to produce medicines and hormones.

DNA technology is used to identify mutations.

DNA technology is used to map human genes on chromosomes.

DNA technology is used to identify paternity.

Answer 1

All five statements are True.

- DNA technology is used to identify hereditary diseases — True (genetic testing, carrier screening, and sequencing detect disease-causing variants).
- DNA technology is used to produce medicines and hormones — True (recombinant DNA and biotechnology produce insulin, growth hormone, monoclonal antibodies, vaccines, etc.).
- DNA technology is used to identify mutations — True (sequencing, PCR, and mutation-detection assays reveal point mutations, insertions/deletions, and other variants).
- DNA technology is used to map human genes on chromosomes — True (linkage analysis, physical mapping and the Human Genome Project located genes and genomic regions on chromosomes).
- DNA technology is used to identify paternity — True (DNA profiling/STR analysis provides high-confidence parentage testing).
