Questions Related to biotechnology: general introduction
Biotechnology is use of
-
Industries
-
Organisms
-
Plants
-
None of the above
Biotechnology is the use of biological processes, organisms, or systems to manufacture products intended to improve the quality of human life. The earliest biotechnologists were farmers who developed improved species of plants and animals by cross pollination or cross breeding.
What are GMOs?
-
Genetically modified organisms
-
Gross modified organisms
-
Genetically multiplied organisms
-
All of the above
Which of the following is not an antibiotic?
-
Griseofulvin
-
Cephalosporin
-
Citric acid
-
Streptomycin
-
Both (A) and (C)
Citric acid is a weak organic acid with the formula -CHO. It is a natural preservative or conservative which occurs naturally in citrus fruits and is also used to add an acidic or sour taste to foods and drinks. Griseofulvin is an orally administered antifungal drug. It is used both in animals and humans, to treat fungal infections of the skin and nails. Whereas cephalosporins are a group of broad spectrum, semi-synthetic beta-lactam antibiotics derived from the mould Cephalosporium. Streptomycin is an antibiotic (antimycobacterial) drug, the first of a class of drugs called as aminoglycosides to be discovered,
Recombinant DNA technology is also called
-
Biotechnology
-
Modern biotechnology
-
Genetic engineering
-
Transgenic technology
The correct option is C
Genetic engineering is connected with
-
Development of transgenic plants
-
Development of vaccination
-
Gene therapy
-
All the above
Modern biotechnology is based on
-
Protoplast fusion
-
Tissue culture
-
Recombinant proteins
-
Genetic engineering
Modern biotechnology is based on the the methods of genetic engineering. It is a technique which involves the introduction of foreign DNA carrying the desired gene of interest into the host organism & thus change the phenotype of the host organism.
