Question

The introduction of a gene sequence into a cell with the aim of modifying the cell's behaviour in a clinically relevant fashion is termed as?

• A. Gene therapy
• B. DNA technology
• C. Cell technology
• D. DNA therapy

Hint:

Think of "DNA technology" as the large toolbox (with tools like gene editing, PCR, etc.) and "Gene therapy" as one specific job you can do with those tools: fixing a disease at the genetic level.

Answer 1

The Correct Option is A

Step 1: Deconstruct the definition. Step 1: The process described is:

Introducing a "gene sequence".
Into a "cell".
To "modify the cell's behaviour".
For a "clinically relevant" purpose (i.e., to treat or cure a disease).
Step 2: Match the definition to the options.
Step 2:

Gene therapy: This is the precise term for an experimental technique that uses genes to treat or prevent disease. The process involves introducing genetic material into a person's cells to compensate for abnormal genes or to make a beneficial protein. This perfectly matches the description.
DNA technology: This is a very broad term that encompasses any technique used to analyze, modify, or create DNA, including DNA sequencing, PCR, and genetic engineering. Gene therapy is a specific application of DNA technology.
Cell technology: This is a general term for methods involving the manipulation of cells, such as cell culture or stem cell research.
DNA therapy: While it sounds similar, "Gene therapy" is the standard and more accurate scientific term.
Step 3: Conclude the most accurate term.
Step 3: Gene therapy is the most specific and correct term for the clinical application described.
