Answer: Option A. ->
True
:
A
A Japanese company called Hayashibara made bioplastic by using simple sugar derived from the fungus Pullularia pullulans. They constructed a polysaccharide called ‘pullulan’ which possessed the physical properties of plastic but was also biodegradable as it was made of only sugars.

Answer: Option B. ->
To monitor the effect of GMO on humans and environment
:
B and C
Bioethical committees aim to make decisions regarding the validity of GM research and the safety of introducing GM-organisms for public services. They also regulate the use and distribution of a GMO after considering its effect on humans and the environment as a whole. They regulate the extent of gene manipulation so that genetic information is not used as a weapon in bio-warfare.

Answer: Option A. ->
Finn dorset ewe and Scottish blackface ewe
:
A
:
A
Dolly was cloned using the process of nuclear transfer. Three female sheep were used to produce the clone.The udder cell from a finn Dorset was taken. This is a somatic cell. The nucleus was removed and then inserted into an enucleated egg cell from a scottish blackface ewe. This zygote was allowed to develop into an embryo and then introduced into the uterus of another scottish blackface ewe. Even though the enucleated egg cell and the surrogate mother both were blackface ewes the offspring dolly was born as a Finn Dorset.

Answer: Option A. ->
It has improved learning and memory
:
A and D
:
A and D
The Smart Mouse is genetically modified to have improved learning and memory. It has extra copies of a gene called NR2B that encodes for certain receptors found in the synapse region of nerve cells in the brain.
Answer: Option C. ->
Understand the genetic disposition of the patients who had positive result
:
C and D
Trying a higher dosage of the drug may help a few patients but may be lethal to others. The same is true when another drug is used.
Pharmacogenomics is the the branch of genetics which deals with determining the likely response of an individual to therapeutic drugs.
In genetic diagnostic testing, specific molecular assays that measure levels of proteins or genes or specific mutations are used to stratify disease status, select from among different medications and tailor dosages, thereby providing a specific therapy for an individual's condition.

Answer: Option B. ->
Getting insulin assembled into its mature form
:
B
The main challenge for production of insulin using rDNA technique was getting insulin assembled into its mature form. The primitive form of insulin called proinsulin contains the C peptide which is not a part of mature insulin. Therefore the scientists had to make the mature insulin using reverse transcriptase and the mature mRNA of the insulin gene. This method is known as cDNA technology, where complimentary DNA sequene of the mRNA is made and inserted as a gene of interest into the bacteria.

Answer: Option C. ->
Only i, iii and iv
:
C
Useful biological products are obtained from transgenic animals to treat diseases like Emphysema, Cystic fibrosis and Phenylketonuria. The treatment of AIDS is the use of antivirals that are not obtained from transgenic animals.

Answer: Option B. ->
Dr. MS Swaminathan
:
B
Dr. MS Swaminathan is known as the ‘Indian Father of Green Revolution’ for his leadership and success in introducing and further developing high-yielding varieties of food grains in India. The extensive work done by him and his team in this field helped India become self-sufficient in the production of food grains, especially Wheat.

Answer: Option D. ->
It amplifies the genetic material
:
D
AIDS can be detected by PCR (polymerase chain reaction) at early stages as it amplifies the genetic material millions of times. Thus the presence of even a tiny number of viruses can give a positive result to the diagnostic test.
