What is the primary goal of genetic screening?

• A. To cure existing diseases
• B. To identify genetic disorders or carrier status
• C. To enhance viral vectors
• D. To replace damaged genes

Answer: (B)

The primary goal of genetic screening is to identify genetic disorders or carrier status. This process involves testing individuals or populations to discover genetic mutations that may lead to inherited conditions or predispositions to certain diseases. By identifying these genetic factors, healthcare providers can offer valuable information and counseling regarding potential health risks, family planning, and preventative measures.

While the other options touch on areas related to genetics, they do not align with the main focus of genetic screening. For instance, curing existing diseases is not the direct aim of screening, as it primarily functions to detect potential risks rather than treat conditions. Similarly, enhancing viral vectors and replacing damaged genes are aspects of therapeutic approaches in genetic engineering, rather than the goal of screening. Overall, genetic screening's essential role is to provide insights into genetic health, helping individuals make informed decisions about their health care and family planning.
