Solution and Explanation
The process described in the question pertains to the use of gene targeting and amplification in an individual's tissue, aiming to treat a disease. This specific intervention is termed as Gene Therapy. Let's delve into a detailed explanation:
- Understanding Gene Therapy: Gene therapy is a technique where genes are used to treat or prevent disease. This is done by introducing, removing, or altering the genetic material within a person's cells to correct the underlying problem.
-
Mechanism of Gene Therapy:
- The process usually involves inserting a functional copy of a gene into a patient’s cells, which is most commonly achieved through a vector, such as a virus, to deliver the gene.
- Amplification, or increase in gene copy number, might also be used to enhance the expression of a therapeutic gene to achieve the desired effect.
- Diseases Treated by Gene Therapy: Currently, gene therapy is utilized for treating genetic disorders, certain types of cancer, and viral infections. For instance, it has shown promise in treating severe combined immunodeficiency (SCID) and some types of inherited blindness.
-
Eliminating Other Options:
- Safety Testing: This involves evaluating the safety and potential side effects of a treatment or intervention, not specifically related to gene manipulation.
- Biopiracy: Refers to the unethical appropriation of indigenous knowledge or biological resources, unrelated to the gene targeting for therapeutic use.
- Molecular Diagnosis: Involves diagnosing diseases at a molecular level, such as identifying gene mutations, and is not a therapeutic intervention.
- Conclusion: Given that the question involves gene amplification for treatment purposes, the correct answer is Gene Therapy.

Anatomy of Dicotyledonous and Monocotyledonous Plants
Dicot Root:
- Dicot plants have the taproot system.
- The outermost layer is called the epidermis. The epidermal cells sometimes project out which appear as the root hairs.
- The epidermis is followed by the multi-layered cortex, loosely made of the parenchyma cells with intercellular spaces.
- The inner layer of the cortex is called endodermis, which is tightly packed by the barrel shaped-cells.
- Endodermis is followed by pericycle, which are a few layers of thick-walled parenchyma cells.
- In dicots, the central pith is not distinct.
- There are two to four xylem and phloem.
- The xylem and phloem are remarked by a layer of parenchymatous cells known as conjunctive tissue.
Monocot Root:
Monocot roots do not show much difference in the anatomy from that of the dicot roots.
- Monocot plants possess an adventitious root system.
- As in the dicots, the epidermis forms the outermost layer, followed by cortex, pericycle, endodermis, vascular bundles (xylem and phloem) and pith (random order).
- Pith is conspicuous and large.
- The number of xylem in a monocot is six or more.
- Secondary growth is not seen in the monocot plants.
