Select the incorrect matched pair.

  1. Monoclonal antibodies - Hybridomas

  2. PCR - Phenylketonuria

  3. Bioweapons - Bacillus anthracis

  4. Tracy - First transgenic animal for food production
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tracy is a transgenic sheep, but the term 'first transgenic animal for food production' is not the standard descriptor for her; she was designed for pharmaceutical protein production (molecular farming). However, in the context of typical exam distractors, this is the intended incorrect pair compared to the others which are standard textbook associations.

A human protein which is obtained from transgenic animals and is used to treat emphysema is 

  1. Alpha-lactalbumin

  2. Thyroxine
  3. $\alpha-1$-antitrypsin

  4. Insulin.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A human protein which is obtained from transgenic animals and is used to treat emphysema is α−1-antitrypsin. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA which codes for particular product such as human proteins. 

So, the correct option is 'Option C' .

Given below are certain features of mice. Read them and select why mice is most preferred animal for studies on gene transfer.


(i) Short estrous cycle and gestation period
(ii) Relatively short generation time
(iii) Convenient in vitro fertilisation
(iv) Production of several offspring per pregnancy 

  1. (i) and (ii) only

  2. (i) only

  3. (i), (ii) and (iv) only

  4. (i), (ii), (iii) and (iv)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mouse is the most preferred animal for studies on gene transfer due to many favourable features like short oestrous cycle and gestation period, relatively short generation time, production of several offspring per pregnancy, convenient in vitro fertilisation, successful culture of embryo in vitro, etc.

Read the following statements : 
I) Mule is developed by interspecific hybridisation
II) Groups of bees is called 'swarms'
III) For the herd-improvement cross-breeding is employed
IV) In MOET, fertilised egg at 6-8 celled stage is recovered non - surgically

  1. I, II, III, IV are true

  2. III , IV, V are false

  3. I, II, IV are true

  4. I, II, III and V are true
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • As a mule is produced by crossing a female horse with a male donkey, it can be said to be an interspecific hybrid.
  • Swarming can be defined as the process by which a queen bee forms a new colony. Consequently, the term ‘swarms’ is used to refer to the colonies of honey bees.
  • Cross-breeding enables the production of hybrids that are superior in one respect or the other to their respective parents.
  • In MOET, the female is made to produce more eggs than normal, usually 6-8. After the fertilization of these eggs with sperms, these fertilized eggs are non-surgically removed and transferred to other females.
Hence, the correct answer is 'I, II, III, IV are true'.

The injecting of foreign gene in an animal gives rise to 

  1. Transgenic animal

  2. Transgenic organism

  3. Transgenic plant

  4. Transcribed animal
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome. Such, animals are most commonly created by micro-injection of DNA into the pronuclei of a fertilized egg which is implanted into the oviduct of a pseudopregnant surrogate mother. This results in the recipient giving birth to genetically modified offspring.

The gene transfer in eukaryotic cells is also known as 

  1. Transformation

  2. Transfection

  3. Transduction

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Transformation is typically used for bacteria, while transfection refers to the introduction of foreign nucleic acids into eukaryotic cells. Transduction specifically refers to virus-mediated gene transfer.
