Which of the following would be a reason to use bacteria or yeast to synthesize human proteins through genetic engineering?

Which of the following would be a reason to use bacteria or yeast to synthesize human proteins through genetic engineering? … Large quantities of the protein can be made easily.

How does recombinant DNA technology help in the production of vaccines?

A recombinant vaccine is a vaccine produced through recombinant DNA technology. This involves inserting the DNA encoding an antigen (such as a bacterial surface protein) that stimulates an immune response into bacterial or mammalian cells, expressing the antigen in these cells and then purifying it from them.

Is commonly used in recombinant DNA technology?

Restriction endonucleases are most widely used in recombinant DNA technology.

What is the main principle behind rDNA technology?

The principle of recombinant DNA technology involved four steps. The four steps are: (1) Gene Cloning and Development of Recombinant DNA (2) Transfer of Vector into the Host (3) Selection of Transformed Cells and (4) Transcription and Translation of Inserted Gene.

Why is bacteria used in cloning?

DNA cloning is a molecular biology technique that makes many identical copies of a piece of DNA, such as a gene. … Bacteria with the correct plasmid are used to make more plasmid DNA or, in some cases, induced to express the gene and make protein.

What features of DNA make it possible to make recombinant DNA in the lab?

Restriction enzymes have two properties useful in recombinant DNA technology. First, they cut DNA into fragments of a size suitable for cloning. Second, many restriction enzymes make staggered cuts that create single-stranded sticky ends conducive to the formation of recombinant DNA.

What are the major discoveries that led to the development of recombinant DNA technology?

Another important tool for creating recombinant DNA was the discovery in the 1960s by the Swiss microbiologist Werner Arber and American biochemist Stuart Linn that bacteria could protect themselves from attack by viruses the production of endonucleases, known as restriction enzymes, which could seek out a single DNA …

Why bacteria are useful in biotechnology?

The biotechnology industry uses bacterial cells for the production of biological substances that are useful to human existence, including fuels, foods, medicines, hormones, enzymes, proteins, and nucleic acids. … Genes can be introduced into plants by a bacterium Agrobacterium tumefaciens.

How are bacteria used in genetic engineering to produce medicine?

Using restriction enzymes, scientists can cut and paste together DNA from different species. For example, by cutting and pasting the gene for human insulin into bacteria, we can use the bacteria as biofactories to produce insulin for diabetic patients.

Why are microbial organisms important as tools in biotechnology?

Microbial biotechnology, enabled by genome studies, will lead to breakthroughs such as improved vaccines and better disease-diagnostic tools, improved microbial agents for biological control of plant and animal pests, modifications of plant and animal pathogens for reduced virulence, development of new industrial …

What is an advantage of using genetically engineered bacteria to produce human proteins?

What is an advantage of using transgenic bacteria to produce human proteins? Transgenic bacteria can produce human proteins in large amounts because bacteria reproduce rapidly. A cell takes in DNA from outside the cell.

How can bacteria be genetically engineered to produce a human protein?

Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory.

How can bacteria be genetically modified?

A small piece of circular DNA called a plasmid? is extracted from the bacteria or yeast cell. A small section is then cut out of the circular plasmid by restriction enzymes, ‘molecular scissors’. The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified.

How does recombinant DNA technology help in environment?

Applications of recombinant DNA technology are discussed as a backdrop for evaluation of the environmental impacts of this technology. Some of applications include using traditional biological techniques for specific purposes, including nitrogen fixation, microbial pesticides, and waste treatment.

What is the importance of recombinant DNA technology in environment?

This technology has multidisciplinary applications and potential to deal with important aspects of life, for instance, improving health, enhancing food resources, and resistance to divergent adverse environmental effects.

How can knowledge of recombinant DNA technology be useful in addressing issues and concerns in society?

Recombinant DNA technology is likely to also have profound effects on society, including better health through improved disease diagnosis, much better understanding of human gene variation, improved drug and pharmaceutical production, vastly more sensitive and specific crime scene forensics , and production of …

Which of the following is a product of recombinant DNA technology?

Biochemical products of recombinant DNA technology in medicine and research include: human recombinant insulin, growth hormone, blood clotting factors, hepatitis B vaccine, and diagnosis of HIV infection.

What is recombinant DNA technique?

​Recombinant DNA (rDNA)

= Recombinant DNA (rDNA) is a technology that uses enzymes to cut and paste together DNA sequences of interest. The recombined DNA sequences can be placed into vehicles called vectors that ferry the DNA into a suitable host cell where it can be copied or expressed.

What are the advantages of using recombinant DNA to produce human hormones such as somatotropin?

Beside cancer, recombinant DNA has been used to treat other diseases also. To treat the disease of diabetes, insulin is produced using recombinant DNA technology. It is now possible to produce insulin in the laboratory which is similar to the human insulin produced by pancreas.

Which bacteria is used in production of insulin by genetic engineering?

E. coli is used in the production of insulin by genetic engineering.

Why is recombinant DNA technology so important to the development of vaccines?

The development of rDNA technologies has provided new ways of attenuating disease agents by modifying their genetic makeup, or ge- nomes, to create safer, more efficacious vaccines. The genome of all living beings is made up of many genes that define the characteristics of the organism.

How is recombinant DNA technology used in the practice of medicine?

Recombinant DNA technology has applications in health and nutrition. In medicine, it is used to create pharmaceutical products such as human insulin. … The cut-out gene is then inserted into a circular piece of bacterial DNA called a plasmid. The plasmid is then re-introduced into a bacterial cell.

Why are bacteria used in recombinant DNA technology?

Bacteria are used in recombinant technology due to various reasons. They contain extrachromosomal DNA called plasmid, which can replicate independently. They are easier to manipulate and replicate rapidly in a medium. Transformants can be easily screened, selected and transferred to the target cells.

Why can recombinant DNA be expressed in any kind of organism even if it contains DNA from another species?
