PATHOLOGY MCQ

GENETICS AND DISEASE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Advances in biotechnology, especially regarding genetic testing and gene therapy, now allow for the screening and possible treatment of many genetic disorders. During gene therapy, for example, specific gene sequences are inserted into an individual’s cells and tissues to replace a defective or mutant allele.What have scientists found to be the most efficient and effective way to insert new sequences into an individual?
A
Scientists inject DNA strands into cells using a syringe.
B
Scientists have created genetically altered foods that release DNA during digestion.
C
Scientists use viruses to insert specific gene sequences.
D
Scientists irradiate genes so that they can be absorbed through the skin.
Explanation: 

Detailed explanation-1: -Using pharmacogenomics, pharmaceutical companies can create drugs based on the proteins, enzymes, and RNA molecules that are associated with specific genes and diseases. These tailor-made drugs promise not only to maximize therapeutic effects, but also to decrease damage to nearby healthy cells.

Detailed explanation-2: -CRISPR/Cas9 Gene Editing Boosts Effectiveness of Ultrasound Cancer Therapy. Dec. 8, 2021-Sonodynamic therapy uses ultrasound in combination with drugs to release harmful reactive oxygen species (ROS) at the site of a tumor.

Detailed explanation-3: -Genome editing is a newer technique that may potentially be used for gene therapy. Instead of adding new genetic material, genome editing introduces gene-editing tools that can change the existing DNA in the cell.
