  1. Kalyan Sona wheat

  2. Sweet sorghum

  3. Hybrid bajra

  4. Golden rice
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Golden rice is a genetically modified variety of rice engineered to produce beta-carotene, which the body converts into vitamin A.

In genetic engineering, which of the following is used?

  1. Plasmid

  2. Plastid

  3. Mitochondria

  4. Endoplasmic reticulum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering mainly aims at the transfer of genes of desired protein products between the organisms. Plastids are double membrane bound organelles that serve as the site for photosynthesis. Mitochondria are double membrane bound eukaryotic cell organelles that serve as the site for cellular respiration, produce an enormous amount of energy. ER is eukaryotic organelle with a network of tubules, vesicles, and cisternae within the cells. It serves to synthesis and transport of proteins and lipids. Plasmids are low molecular weight extrachromosomal DNA that carries origin of replication, restriction sites and selectable markers to confer readily selectable phenotypic traits on host cells. Plasmids require very few genes for their own replication and rest of it can be deleted and foreign sequences can be added to the plasmid which in turn makes them a suitable candidate to serve as a vector for gene transfer. Thus, the correct answer is option A.

Which of the following bacteria are used in study of 'genetics'?

  1. E. coli

  2. Bacillus

  3. Pseudomonas

  4. Rhizobium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
E. coli is the most well-understood bacterium and is an extremely important model organism in many fields of research, particularly molecular biology, genetics, and biochemistry. It is easy to grow under laboratory conditions, and research strains are very safe to work with. As with many bacteria, E. coli grows quickly, which allows many generations to be studied in a short time. Under ideal conditions, E. coli cells can double in number after only 20 minutes. The genetics of E. coli are well-understood and can be readily manipulated.
Therefore, the correct answer is option A.

Which of the following is related with genetic engineering?

  1. Golgi apparatus

  2. Lysosomes

  3. Mitochondria

  4. Plasmid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic engineering mainly aims at the transfer of genes of desired protein products between the organisms. Lysosomes are the suicidal bags of cell that digest and remove the wear and tear organelles and molecules from the cell. Golgi body consist of flattened sacs stacked on each other, that serve to processes secretory and synthetic products from the ER and then transport the finished products into cell part or secretes them to the outside of the cell. Mitochondria are double membrane bound eukaryotic cell organelles that serve as the site for cellular respiration, produce an enormous amount of energy and therefore are also known as a power house of cell. Plasmids are low molecular weight extrachromosomal DNA that carries origin of replication, restriction sites and selectable markers to confer readily selectable phenotypic traits on host cells. Plasmids require very few genes for their own replication and rest of it can be deleted and foreign sequences can be added to the plasmid which in turn makes them a suitable candidate to serve as a vector for gene transfer. Thus, the correct answer is option C.

Radiology deals with the study of

  1. UV rays

  2. Gamma rays

  3. Cosmic rays

  4. X-rays
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Radiology is a medical specialty that uses imaging to diagnose and treat disease seen within the body. Radiologists use a variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI) to diagnose or treat diseases.

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.
