In transgenics, expression of transgene in target tissue is determined by which of the following segment?

  1. Enhancer

  2. Promotor

  3. Transgene

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

A reporter gene is a gene that researchers attach to a regulatory sequence of another gene of interest in bacteria, cell culture, animals or plants. It determines the action of transgene in transgenic plants and animals.

Which one of the following sets of plant show/have shown promise as potential hydrocarbon(petroleum) sources?

  1. Simmondsia chinensis, Euphorhia ahvssinica, E. Teracalli

  2. Hardwockia pinnate, Capaifera longsorfii, Euphorbia esinifera

  3. Capaifera multijuga, Euphrobia lathyrus, caloropis procera

  4. Sesamum indicum, Linum usitatissimum, Arachis hypogea
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Simmondsia chinensis (jojoba), Euphorbia abyssinica, and Euphorbia terracalla have shown promise as potential hydrocarbon or petroleum-like sources. Jojoba produces liquid wax esters similar to sperm whale oil, while certain Euphorbia species produce latex containing hydrocarbon-like compounds. Options B and C contain misspelled or incorrect plant names. Option D lists conventional oilseed plants (sesame, linseed/flax, peanut) that produce edible oils, not petroleum-like hydrocarbons.

What does make farm animals most susceptible?

  1. Lead toxicity

  2. Florine toxicity

  3. Sulfur toxicity

  4. Nox toxicity
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fluorine toxicity (fluorosis) is a significant health issue in livestock, often caused by the ingestion of forage contaminated with industrial emissions or high-fluoride water. It leads to skeletal deformities and dental issues, making animals highly susceptible to health decline.

Main objective of production of herbicide resistant GM crops is to?

  1. Encourage eco-friendly herbicides

  2. Reduce herbicide accumulation in food articles for health safety

  3. Eliminate weeds from the field without the use of manual labour

  4. Eliminate weeds from the field without the use of herbicides
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Herbicide-tolerant plants are plants whose growth and development are not significantly affected by herbicides used on the weeds growing around them. 

These types of plants were developed to help farmers control weeds without the use of manual labour that competes with crops for soil, space, water, and sunlight. 
So, the correct option is 'Eliminate weeds from the field without the use of manual labour'.

How can we increase the food production?

  1. By agrochemical based agriculture

  2. By Organic agriculture

  3. By genetically engineering crop- based agriculture.

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

Organic agriculture will help improve food production as it involves production system that relies on ecological processes, biodiversity and cycles adapted to local conditions and does not involve the use of pesticides, fertilizers or other genetically modified organisms etc. Use of genetically modified crop-based agriculture techniques, on the other hand, will help increase yield and also provide the plants with resistance to diseases. 


So, the correct option is 'By genetically engineering crop- based agriculture'.

Which of the following is not a genetically modified organism (GMO)?

  1. Golden rice

  2. Rosie

  3. Dogie

  4. Dolly
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A genetically modified organism is any organism whose genetic engineering techniques. GMOs are used to produce many medications and genetically modified foods and are widely used in scientific research and the production of other goods. For example, Golden rice, Rosie, and Dolly.
So the correct answer is 'Dogie'.

  1. 1 only

  2. 2 only

  3. 1 and 3 only

  4. 1, 2, 3 and 4
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biotechnology is an applied branch, which involves the use of bioanalytical techniques. This branch is mainly associated with the genetic engineering, which helps in the modification of organisms.

Therefore the right answer is option "D, 1,2,3 and 4".

Extensively used tool in genetic engineering of crop plants is _________________.

  1. Agrobacterium mediation

  2. Protoplast fusion

  3. Transposons

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

Transposons are basically jumping genes. Protoplast fusion is a technique of creating hybrids, the mating of one species protoplast and other species protoplast. While microinjection is a method of injecting our interest of DNA directly into the host. We can achieve transformation by microinjection too but Agrobacterium-mediated transformation is most commonly used. Agrobacterium tumefaciens is a naturally occurring soil bacterium causing crown gall disease and has the ability to introduce new genetic material into the plant cell. 

Hence, the correct answer is 'Agrobacterium-mediation'.
