Plasmids are small, circular, double-stranded DNA molecules that are distinct from a cell's chromosomal DNA and can replicate independently. They are commonly used as vectors in genetic engineering.
What is the definition of biotechnology?
Biotechnology involves using living organisms or their systems to develop or make products for human benefit.
What are the two major types of anaerobic fermentation?
The two major types of anaerobic fermentation are lactic acid fermentation and ethanol fermentation, which are used in various industrial applications.

What gas is produced by yeast in bread dough that makes it rise?
Yeast produces carbon dioxide during alcoholic fermentation, which causes bread dough to rise.
What is the role of restriction enzymes in biotechnology?
Restriction enzymes are used in biotechnology to cut DNA at specific sequences, allowing for the manipulation and study of gene sequences.
What does DNA ligase do?
DNA ligase is an enzyme that facilitates the joining of DNA strands together by forming a bond between the phosphate and deoxyribose groups.
What are plasmids used for in genetic engineering?
Plasmids are used in genetic engineering as vectors to carry and insert specific genes into host organisms, allowing for the expression of desired traits or the production of specific proteins.
What does genetic engineering involve?
Genetic engineering involves the artificial manipulation and recombination of DNA to alter the characteristics of organisms or to produce specific biological products.
What was the first genetically engineered drug produced in 1978?
The first genetically engineered drug produced in 1978 was human insulin, which was created using recombinant DNA technology to produce insulin in bacteria for diabetic patients.
Which of the following is a biotechnology application in medicine?
DNA fingerprinting is a biotechnology application used in medicine and forensic science to identify individuals based on their unique DNA sequences.
What is fermentation?
Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol using microorganisms like yeast or bacteria under anaerobic conditions.
Which organisms are commonly used in fermentation?
Yeast and bacteria are commonly used in fermentation processes to produce a variety of products, including alcohol, bread, and dairy products.
In lactic acid fermentation, pyruvic acid is converted into:
In lactic acid fermentation, pyruvic acid is converted into lactic acid, which is commonly observed in muscle cells during strenuous activity when oxygen is scarce.
Why do muscles feel sore after intense exercise?
Muscles feel sore after intense exercise due to the build-up of lactic acid, which occurs when the body produces energy anaerobically.
In alcoholic fermentation, what are the end products?
In alcoholic fermentation, the end products are ethanol and carbon dioxide, which are produced by yeast under anaerobic conditions.
What is the first step in the genetic engineering process?
The first step in the genetic engineering process is identifying the gene that produces the protein of interest, which will be manipulated or inserted into another organism.
What are restriction enzymes primarily used for in genetic engineering?
Restriction enzymes are primarily used in genetic engineering to cut DNA at specific sequences, allowing for the manipulation and study of gene sequences.
What is the function of ligase?
Ligase is an enzyme used to paste or join DNA fragments together, which is crucial in genetic engineering for creating recombinant DNA.
What is a plasmid?
A plasmid is a small, circular, double-stranded DNA molecule that is separate from chromosomal DNA and can replicate independently. Plasmids are commonly used as vectors in genetic engineering.
What are genetically modified organisms?
Genetically modified organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques, often involving the insertion of recombinant DNA.
What is the purpose of inserting recombinant DNA into a host cell?
The purpose of inserting recombinant DNA into a host cell is to produce a desired protein, which can be used for various applications in medicine, agriculture, and industry.
How was insulin production improved using genetic engineering?
Insulin production was improved using genetic engineering by inserting the human insulin gene into E. coli bacteria, which then produce insulin that can be harvested and purified for human use.
What is the gene called that suppresses cancer cells?
The p-53 gene is known as a tumor suppressor gene that plays a crucial role in preventing cancer by regulating cell division and preventing the proliferation of damaged cells.
Which organism is commonly used as a host to produce insulin through recombinant DNA?
E. coli is commonly used as a host organism to produce insulin through recombinant DNA technology due to its rapid growth and ease of genetic manipulation.
What is the significance of bacteriophages in genetic engineering?
Bacteriophages are viruses that infect bacteria and can be used in genetic engineering as vectors to carry recombinant DNA into bacterial cells.
