Questions Related to transgenic organisms

The enzymatic degradation of lactose in dairy product can reduce the__________.

  1. Casein

  2. Whey

  3. Microbes

  4. Acrylamide


Correct Option: D
Explanation:

Acrylamide does not form, or forms at lower levels, in dairy, meat, and fish products. so the enzymatic degradation of lactose in dairy produts can reduce the acrylamide.

What was the amount of Alpha-lactalbumin in the milk of transgenic cow?

  1. $2.4$ grams/lit

  2. $4.2$ grams/lit

  3. $3.4$ grams/lit

  4. $4.3$ grams/lit


Correct Option: A
Explanation:

Alpha-lactalbumin is a major milk whey protein. It is involved in the process of lactose synthesis. The first transgenic cow was produced with human alpha-lactalbumin gene introduced into it. The milk of transgenic cow contained about 2.4 grams/lit of human protein.

Thus, the correct answer is '2.4 grams/lit.'

All of the followings are associated with replacement principle of animal biotechnology except

  1. Cell culture

  2. Computer models

  3. Epidemiological studies

  4. Improving experimental technique


Correct Option: D

First transgenic mouse grew twice the normal size after drinking -------- containing water.

  1. Cu

  2. Fe

  3. Zn

  4. Ra


Correct Option: C
Explanation:

When the transgenic mice were a few weeks old, they were given drinking water containing zinc. Mice carrying the transgene grew to twice the size of their litter mates because the metallothionein enhancer sequence stimulated by zinc had increased growth hormone production.

More than $95\%$ of transgenic animals are.

  1. Rabbits

  2. Mice

  3. Fish

  4. Cows


Correct Option: B

The Transgenic animals are generally produced for all of the following needs EXCEPT.
