Question 1
1 / -0

Sir Alexander Flemming extracted Penicillin from?

A
Penicllium citrinum

B
Penicllium notatum

C
Penicllium chrysogenum

D
Bacillus brevis

Solution

First antibiotic Penicillin from blue - green fungus Penicillium notatum in agar - agar medium, was discovered by Sir Alexander Flemming in 1928.
So, the correct answer is 'Penicllium notatum'
Question 2
1 / -0

Antibiotic Flavicin is obtained from

A
Aspergillus flavus

B
Aspergillus clavatus

C
Streptomyces griseus

D
Streptomyces fradice

Solution

Aspergillus flavus is the fungi which grows on plants such as peanut plant. It is used in the production of the antibiotic Flavicin. It is also used to produce the carcinogenic substance Aflatoxin.
Question 3
1 / -0

Which is the first biochemical to be produced commercially by microbial cloning and genetic engineering ?

A
Human insulin

B
Penicillin

C
Interferons

D
Fertility factors

Solution

Synthetic human insulin was the first biochemical product which is produced commercially by recombinant DNA technology. Before that insulin was extracted from the pig which mimics like human insulin. Currently, millions of diabetics worldwide use synthetic insulin to regulate their blood sugar levels. Synthetic insulin is made in both bacteria and yeast.
Question 4
1 / -0

Which of the following organelles is related with genetic engineering?

A
Golgi apparatus

B
Lysosomes

C
Mitochondria

D
Plasmids

Solution

A plasmid is a small DNA molecule that is physically separate from, and can replicate independently of, chromosomal DNA within a cell. Plasmids play an integral role in genetic engineering experiments. In genetic engineering, DNA is required to move from test-tube environment to cellular environment. Plasmid being small in size makes it easier to complete this task.
Therefore, the correct answer is option D.
Question 5
1 / -0

Which of these is widely used in genetic engineering?

A
Butterfly

B
Dragon fly

C
Dragon lizard

D
Fruit fly
Solution
- Drosophila melanogaster is a species of fly in the family Drosophilideae.
- The species is known as the common fruit fly or vinegar fly.
- It is typically used in genetic engineering because it is an animal species that is easy to care for, has four pairs of chromosomes, breeds quickly, and lays many eggs.
Question 6
1 / -0

'ANDi' is a cloned

A
Sheep

B
Bull

C
Monkey

D
Cat

Solution

'ANDi' is the first genetically modified rhesus monkey, who was born at Oregon Health Sciences University in 2000. OSHU named the monkey ANDi because it stands for 'inserted DNA' spelled backward.
Question 7
1 / -0

Genetically engineered human insulin is prepared by using which microbe?

A
E. coli

B
Rhizopus

C
Pseudomonas

D
Yeast

Solution

When E.coli reproduces, the insulin gene is replicated along with the plasmid, a circular section of DNA. E.coli produces enzymes that rapidly degrade foreign proteins such as insulin. By using mutant strains that lack these enzymes, the problem is avoided.
Question 8
1 / -0

Why the production of a human protein in bacteria by genetic engineering became possible?

A
Bacterial cell can carry out the RNA splicing reactions

B
The human chromosome can replicate bacterial cell

C
The mechanism of gene regulation is identical in humans and bacteria

D
The genetic code is universal

Solution

Genetic engineering was proved very much successful because of the universal acceptance of genetic code. It means, all the organisms have the same pairing properties of their base pairs on DNA. Each codon codes for the same aminoacid in all organisms.
Question 9
1 / -0

Polyethylene glycol method is used for which of the following techniques?

A
Gene transfer without a vector

B
Biodiesel production

C
Seedless fruit production

D
Energy production from sewage

Solution

Polyethylene glycol method is also called as PEG. Foreign DNA is introduced into protoplasts prepared protonemata. Regeneration rate of protoplasts is one of most critical factors for transformation efficiency. Protonemata grown for 3 to 6 days after subculture should be used for isolating protoplasts.
Question 10
1 / -0

Choose the correct statement with reference to "Dolly".

A
She was created by taking nucleus from unfertilised egg.

B
She was created by taking nucleus from udder cell and cytoplasm from unfertilised egg.

C
She was created by taking cytoplasm from udder cells and nucleus from fertilised egg.

D
She was created in the test tube.

Solution

To produce Dolly, sheep a cloned animal where the fin Dorset mammary cell nucleus is injected into the Scottish Blackface ewe oocyte with the help of electricity. The new fused cell is them implanted into a surrogate mother, another Scottish Blackface ewe which develops sheep a clone of fin Dorset sheep. Thus, the correct answer is option B.
