the human insulin gene, which is located on the top of the short arm of chromosome 11 in human DNA, is cut from the DNA strand using restriction enzymes (genetics scissors).
a plasmid (floating circular disks of DNA in bacteria) is extracted from a bacteria and cut open with another restriction enzyme, and the gene for human insulin is taken up by the plasmid. Another enzyme, ligase, is used to permanently seal the exposed nucleotides (ends of the DNA strands) together (like genetic glue).
the plasmid is then put back into the bacterial cell, and the bacteria will then manufacture insulin. its offspring will also have the genetic data for human insulin.

Is an example of genetic engineering?
Altering corn for better yield and taste. Producing human insulin from bacteria.
When was Human Insulin produced by mircobes?
In 1983 scientists worked out a way of producing human insulin on a large scale using genetically modified bacteria. They did this by first working out which human chromosome was responsible for producing insulin. They then isolated that chromosome using a restricting enzyme. They would then remove the plasmid from the bacterium, cut out a small piece of the plasmid using enzymes and then replace the gap made with the human insulin gene. The genetically engineered plasmid is the inserted into a new bacterium and this bacterium is allowed to grow and multiply. Each of the new bacteria would contain the human insulin gene and as the bacteria continued to multiply they would be producing insulin which could then be used to treat diabetes. In this way we could produce large amounts of insulin that was suitable for vegetarian use and causes very few allergic reactions quickly and cost effectively.
Which organ is responsible for producing the hormone insulin to lower blood sugars in the human body?
Pancreas is an endocrine gland that contain cells known as beta cells that produces insulin.
Which best describes how scientistists found the human gene that makes insulin?
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.
Islets of Langerhans are specialized cells found in the?
They are tiny endocrine producing bodies in the human pancreas.
Is the insulin made by E.coli better or worse than insulin made by human?
The insulin that we engineer bacteria to make (E.colidoes not naturally make insulin) is identical to human insulin.
Why is human insulin preferable to animal insulin?
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.
What is the difference between human and analog insulin?
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.
What is the process of making human insulin with bacteria?
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.
Why is pig insulin being used as a substitute of human insulin?
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.
What is recombinant human insulin?
Insulen used to be "made" by extracting insulin from the pancreases of slaughtered pigs and cows. Aside from the problems with being acceptable to Jewish or Muslim folks the supply was limited. The solution was to re-enginer E. Coli to carry the insulin producing gene. The insulin can now be grown like any pharmaceutical.

What does it mean if a doctor finds glucose in human urine?
It means that the body isn't producing enough insulin to control glucose levels; the patient is probably diabetic.
