Why is it important to cut the plasmid and the human DNA with the same restriction enzyme?
Cutting both the plasmid and the human DNA with the same restriction enzyme is crucial for creating compatible ends that can easily ligate together. This ensures that the DNA fragments can anneal properly, facilitating the formation of recombinant DNA. Using the same enzyme also maintains the specific sequences needed for successful cloning and expression in host cells, enhancing the efficiency of genetic engineering processes.

How does a human insulin genes become part of a plasmid?
1. Scientists remove plasmids, small rings of DNA, from bacterial cells. 2. An enzyme cuts open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome. 3. The human insulin gene attaches the open ends of the plasmid to form a closed ring. 4. Some bacterial cells take up the plasmids that have the insulin gene. 5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.
Whay is then enzyme in human saliva?
The enzyme in human saliva is Amylase.
When scientist copy DNA what do they have to cut out first?
Restriction endonuclease
What evidence is there that protease enzyme came from a human?
Protease enzme came from a human.
Name the enzyme present in human saliva?
A. The enzyme present in the human saliva is called salivary amylase and it starts the chemical digestion of starch. Also, there is another enzyme called lingual lipase which starts the chemical digestion of fats.

When pharmaceutical companies use recombinant bacteria to make insulin what do they insert the insulin gene into?
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.

How is a human gene recombined into a bacterial plasmid?
One of the most common ways these days is from cDNA. RNA is extracted from human cells, purified, and then treated with an enzyme called reverse transcriptase which is able to make DNA from RNA templates (this DNA made from RNA is called cDNA). The advantage of using cDNA is that in the genome human genes are typically distributed across multiple exons spread over tens or even hundreds of thousands of basepairs of DNA. Such a massive segment of DNA is extremely hard to manipulate and far too large to insert into a plasmid. However, in cDNA, all the introns have been spliced out (because cDNA is made from mature mRNA). To isolate a particular gene from cDNA, PCR is often used to selectively amplify one gene's cDNA using specific primers. To insert the amplified cDNA into a plasmid, the traditional approach was to use restriction enzymes - enzymes that cut precise DNA sequences. The great thing about many restriction enzymes is that they cut DNA but leave behind "sticky ends". Thus if you cut both your cDNA and a plasmid with a particular restriction enzyme, the resulting sticky ends will allow the human cDNA to be taken up by the plasmid (the sticky ends will mesh). The sticky ends will have to be sealed by an enzyme called DNA ligase. However, there are other ways these days - often involving recombination to insert the PCR product directly into a plasmid without resorting to restriction enzymes and ligations.
How could you use genetic engineering techniques to make transformed bacteria that produce the enzyme?
Extract DNA from the cells of people who can make the digestion enzyme. Cut the DNA with restriction enzymes to cut out the gene that codes for the enzyme. Use gel electrophoresis to locate the gene. Then, use polymerase chain reaction to make copies of the gene. Choose a plasmid that has an antibiotic-resistance genetic marker, and cut the plasmid with the smae restriction enzyme use to cut out the hyman gene. Insert the copies of the human gene into the plasmids. Allow bacterial cells to take in the plasmids. Select for transformed bacteria by growing them in a culture containing the antibiotic. These bacteria will make the digestion enzyme.

In the process of human gene cloning using recombinant plasmids what is the bacterial plasmid?
The bacterial plasmid is a small circular DNA molecule that is used as a vector to carry the gene of interest in gene cloning experiments. It is introduced into bacteria, where it replicates independently from the bacterial chromosome. The gene of interest is inserted into the plasmid using restriction enzymes and ligase.

A plasmid that contains a gene for human growth hormone is and example of what?
A plasmid containing a gene for human growth hormone can be used in genetic engineering to produce recombinant human growth hormone. This plasmid can be introduced into host cells, such as bacteria, for the production of the hormone on a large scale.

Can genetic engineering techniques treat cystic fibrosis?
Yes, there are two similar techniques in which i am aware of.AdenovirusesFirstly adenoviruses are made harmless by interefering with a gene involved in replication. A healthy from of the CFTR gene is extracted and cut with restriction endonucleases, the same enzyme is used to cut a bacterial plasmid. The gene and plasmid are mixed together along with DNA ligase to anneal the phosphosugar framework of the DNA fragment and bacterial plasmid. The plasmid is then mixed with epithelial cells. The plasmid is then isolated and purified and places into adenoviruses. These are then placed onto the nostrils of individuals with cystic fibrosis. The viruses find their way to epithelial cells in the airways and injected their DNA. The DNA contains the functional CFTR gene, the cells can then produce fucntional CFTR proteins.LiposomesA healthy gene is extracted from a human. This gene is then inserted into a bacterial plasmid, in a similar manner as discussed above. The bacterial plasmids are then inserted into bacteria. These are allowed to grow and divide, producing large quantities of the plasmid, with the required gene. These plasmids are then extracted and coated in a lipid soluble substance. They are then put into nasal sprays and sprayed onto the nostrils of effected individuals.
How bacteria can make human insulin?
Yes, bacteria are used to make insulin. First restriction enzymes cut a human DNA strand where the gene to make insulin is located. Then, that fragment of human DNA is inserted into a bateria plasmid that reproduces and as it reproduces it creates more insulin.
