Weekly Quiz Competition

Question 1
1 / -0.25

Assertion: Bacillus thuringiensis forms protein crystals during particular phase of growth.Reason: These crystals contain a toxic insecticidal protein that kills the certain insects.

A
Both assertion and reason are incorrect

B
Both assertion and reason are correct.

C
Assertion is not explained by reason

D
Assertion is correct but reason is incorrect.

Solution

Bacillus thuringiensis bacterium forms protein crystals during particular phase of growth. The crystal of toxic protein has insecticidal protein. This protein get activated in alkaline medium in the gut of insects and kills them.
Question 2
1 / -0.25

Gene used to treat emphysema is

A
Trypsin 1

B
Beta-1- antitrypsin

C
Alpha 1

D
Alpha- 1- antitrypsin

Solution

Alpha-1-antitrysin gene is used to treat emphysema disease. This disease causes breakdown of alveoli cell and reducing the surface area for exchange of gases.
Question 3
1 / -0.25

The main challenge for production of insulin using rDNA technique was

A
Removing C peptide chain

B
Joining chain A with peptide chain

C
Separating chain A and chain B

D
Getting insulin assembled into a mature form

Solution

The main challenge for production of insulin using rDNA technique was getting insulin assembled into a mature form
Question 4
1 / -0.25

A person born with hereditary disease can be treated by

A
Chemotherapy

B
Gene therapy

C
Medicine

D
Thermal therapy

Solution

Hereditary diseases are due to defects in gene. Gene can be corrected at embryonic stage by gene therapy technique in which genes are inserted into person cells or tissue to take over the function of defective gene.
Question 5
1 / -0.25

The two polypeptide chains in insulin are linked via Sulphur. The bond formed is

A
Peptide bond

B
Glycosidic linkage

C
Disulphide linkage

D
Diester bond

Solution

Two peptide chains A and B in insulin are linked via sulphur to form a disulphide linkage or disulphide bridge.
Question 6
1 / -0.25

A radioactively labeled Probe can be detected by

A
Autoradiography

B
UV rays

C
ELISA

D
PCR

Solution

Radioactively labeled probe can be detected by autoradiography. A single stranded DNA or RNA tagged with a radioactive molecule is allowed to hybridise to its complementary DNA in a clone of cells followed by detecting using autoradiography.
Question 7
1 / -0.25

Mature insulin is different from pro-insulin in

A
Having more number of nucleotides

B
Having more number of amino acids

C
Causing allergic reactions

D
Absence of C-Peptide

Solution

Pro-insulin differ from mature insulin as pro-insulin contain C-peptide which is absent in mature insulin.
Question 8
1 / -0.25

Detection of bands on a southern blot is done by_____.

A
ELISA

B
PCR

C
electrophoresis

D
probe

Solution

Detection of bands on a southern blot is done by probe that contain radioactive single stranded DNA or RNA.
Question 9
1 / -0.25

Transgenic cow Rosie, produced human protein enriched milk that contain:

A
2.4 gram per litre

B
7.4 gram per litre

C
3.5 gram per litre

D
4.2 gram per litre

Solution

Transgenic cow Rossie produced human protein enriched milk that contain 2.4 gram of protein per litre. The milk contained the human alpha-lacalbumin protein.
Question 10
1 / -0.25

For which of the disease transgenic models do not exists now days?

A
Tuberculosis

B
Cancer

C
Cystic fibrosis

D
Alzheimer ’s disease.

Solution

Transgenic model for treatment of disease is available today for cancer, cystic fibrosis, Alzheimer ’s disease and rheumatoid arthritis disease.
Question 11
1 / -0.25

Toxicity of drug on human can be studied by using transgenic animal by

A
Introducing complementary gene into organism

B
Inoculating gene that make them more sensitive to toxic substances

C
Introducing gene that show change in physiology of organism

D
All of the these

Solution

Toxicity of drug on human can be studied by using transgenic animal by Inoculating gene that make them more sensitive to toxic substances and exposing to toxic substance to be studied.
Question 12
1 / -0.25

Assertion: For toxicity testing, transgenic animals are made to carry genes which make them more sensitive to toxic substance.

Reason: Transgenic animals are exposed to toxic substance to be study to know their effect.

A
Assertion is correct but reason is incorrect

B
Both assertion and statements are correct

C
Assertion is incorrect but reason is correct

D
Both assertion and reason are incorrect

Solution

Transgenic animals are used to study the toxicity effects of certain chemical in which animals are made to carry gene which make them more sensitive to toxic substance and exposed to toxic substance to be studied.
Question 13
1 / -0.25

Useful biological products are obtained from transgenic animals to treat disease like
i. Emphysema
ii. AIDS
iii. Cystic fibrosis
iv. Phenylketonuria

A
Only ii, iii and iv

B
Only i, iii and iv

C
Only i, ii and iii

D
Only i, ii and iv

Solution

Useful biological products are obtained from transgenic animals to treat disease like Emphysema, Cystic fibrosis and Phenylketonuria.
Question 14
1 / -0.25

In 1997, an American company got patent rights on

A
Turmeric

B
Basmati rice

C
Maize

D
Soybean

Solution

In 1997, an American company got patent rights on Basmati rice through the US patent and trademark office. This allowed the company to sell a new variety of Basmati in the US and abroad.
Question 15
1 / -0.25

A
Biopiracy

B
Eugenics

C
