Which is considered a superior method for identification of urine sugars?

  1. Endoscopy

  2. Thin layer chromatography

  3. Electrocardiogram

  4. Tomography
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Thin-layer chromatography is a method that is used for the separation and identification of the amino acids and sugars. 
  • There are different substances that may be present in the urine which is excreted by an organism. 
  • Generally, the amount of sugar that is excreted by humans is less. 
  • In the case of diabetic patients, the sugar in the urine can be detected by this method of chromatography in which there is a thin layer of silica gel and the solvent is used with respect to the sugars. 
  • The solvent flows and allows the separation of the different molecules.
  • Thus, the correct answer is option B.

Terminator seeds produced by giant seed companies using techniques of genetic engineering are in fact _________________.

  1. Hybrid seeds which germinate in the frame's field but do not produce seeds in the next generation

  2. Hybrid seeds which give a very high yield

  3. Seed which germinate and produce incompatible gametes

  4. Seeds that develop into fertile plants which produce flog-terminable seeds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Terminator seeds are hybrid seeds that germinate and grow normally but produce sterile seeds in the next generation, preventing farmers from saving seeds. They do not produce flog-terminable seeds or incompatible gametes. The high yield claim is secondary to their terminator characteristic.

Which one is being produced by genetically altered genes _________________.

  1. Calcitonin

  2. Platelet derived growth factor

  3. Erythropoietin

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic engineering allows for the production of various therapeutic proteins, including calcitonin, growth factors, and erythropoietin, using recombinant DNA technology.

Which of the following statements is/are correct? 

  1. The current interest in the manipulation of microbes, plants and animals has raised serious ethical issues.

  2. One possible risk of genetic engineering is the accidental production of antibiotic resistant microorganisms.

  3. Although risks are possible, genetic engineering offers more of a contribution to human welfare than threats.

  4. All of these.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Several animal studies indicate serious health risks associated with genetically modified (GM) food including infertility, immune problems, accelerated aging, faulty insulin regulation, and changes in major organs and the gastrointestinal system.
  • One of the first cases of human benefit from genetic engineering was the production of human insulin in bacterial cells. Previous to this, diabetic patients were treated with pig insulin. Use of bacterially-derived human insulin has substantially reduced the number of animals used to produce insulin and also significantly reduces adverse reactions in diabetic patients as the molecule is identical to human insulin. Since the successful production of genetically engineered insulin, many other human proteins have been produced in this manner. This technology has improved millions of lives.

So, the correct option is 'All of these.'.

Manipulation of DNA to change its structure is called genetic engineering.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering is a technique to alter the chemistry of genetic material (DNA and RNA), to introduce these into the host organisms and thus change the phenotype and genetic makeup of the organism.

So, the statement is 'True'.

Research projects: 

  1. cloning

  2. identical/ non identical twins

  3. triplets/ quadruplets

  4. surrogacy

  5. IVF
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning happens all the time in nature for example, when a cell replicates itself asexually without any genetic alteration or recombination.

So, the correct option is 'Cloning'.
