Understanding Diabetes
Diabetes is a chronic metabolic disorder characterized by high blood glucose levels.
There are two main types of diabetes
: type 1 and type 2.
Type 1 diabetes is an autoimmune disease where the immune system attacks and destroys insulin-producing cells in the pancreas.
Type 2 diabetes occurs when the body becomes resistant to insulin or doesn’t produce enough insulin.

Creation of Transgenic Models
Transgenic models are generated by introducing specific genes into the genome of an animal.
This is achieved through techniques such as gene cloning, recombinant DNA technology, and genetic engineering.
The gene of interest, which is associated with diabetes, is inserted into the animal’s genome.
The animal will then express the gene and develop diabetes-like symptoms.
