They worked backwards from mRNA to DNA.
They figured out the DNA sequence from the amino acid sequence
Genetically engineered insulin may have fewer side effects than the insulin previously extracted from the pancreases of other animals. This is because genetic engineering inserts human genes such as the gene for insulin production into the DNA of bacteria. As a result, the bacteria that produces human insulin, when used by diabetics, should produce fewer side effects.
Human insulin is preferable to animal insulin because it is made through genetic engineering, ensuring higher purity and reducing the risk of allergic reactions. Additionally, human insulin closely mimics the natural insulin produced by the human body, which leads to more predictable and consistent results in managing diabetes. Lastly, human insulin is now more widely available and cost-effective compared to animal-derived insulin.
The process involves inserting the human gene for insulin into a bacterial plasmid, which acts as a vector. The bacteria then replicates the gene and produces insulin protein. The protein is harvested, purified, and formulated into insulin for medical use.
Pig insulin is used as a substitute for human insulin in some cases because it is similar in structure and function to human insulin, making it effective in managing diabetes. Additionally, using pig insulin can be more cost-effective and readily available for some patients compared to human insulin.
Scientists found the human gene that makes insulin by using recombinant DNA technology to clone and sequence the gene. They identified the gene by comparing it to the insulin genes of other species and then inserting the human gene into bacteria to produce insulin for medical use.
They figured out the DNA sequence from the amino acid sequence
Scientists used recombinant DNA technology to isolate the human gene responsible for producing insulin. This involved identifying the gene sequence in bacteria or yeast cells, which could then produce human insulin. By cloning and studying the gene, researchers were able to determine its function and create synthetic insulin for medical use.
Human Insulin, is a replica of the insulin found naturally in human beings. These are synthetically prepared. An insulin analogue however is an altered form of this human insulin, by addition,subsitution or substraction of one/or more amino acid chain/s. This is done to make insulin more safe and effective for human use.

The insulin that we engineer bacteria to make (E.colidoes not naturally make insulin) is identical to human insulin.
Diabetes insulin is found in all four subjects. However, recombinant bacteria are primarily used as a main source of insulin for diabetic subjects.

Scientists made insulin by isolating it from the pancreas of animals, such as pigs and cows, initially. Later, recombinant DNA technology allowed for the production of human insulin using genetically engineered bacteria or yeast cells. This process revolutionized insulin production, making it more widely available and reducing the risk of allergic reactions from animal-derived insulin.
