Find the CORRECT match from the following.

Options:
A Cry I Ab - Cotton bollworms
B RNAi - Meloidogyne incognitia
C First transgenic cow - Dolly
D Eli Lily and company - Gene therapy

The correct answer is:
RNAi - Meloidogyne incognitia

Solution:
Biotechnology has been used extensively in the fields of agriculture and medicine. A disease affecting the cotton plant known as cotton bollworms has been eliminated with the help of biotechnology. Bt toxin gene isolated from Bacillus thuringiensis and incorporated into the cotton plants. Specific gene code for specific toxins. The cry IAc and cryIIAb are useful in the control of cotton bollworm. Another example of the use of biotechnology in agriculture is the development of pest-resistant plants. RNA interference technique was used to overcome the nematode Meloidogyne incognitia which infects and reduces the yield of tobacco plants. The first transgenic cow produced was named Rosie and it produced milk which was rich in human proteins. Elli Lilly is an American company that produced genetically engineered insulin.

Find the correct match in the following:

Options:
A Viruses are smaller in size ranging from 20-400 nm and bacteria is larger in size, around 1000 nm.
B Origin of Solar system: 20 billion years ago and Origin of universe system: 50 billion years ago
C Founder effect operates in a large population and gene flow operates in a small population
D Deep veins are located on the surface of the skin.

The correct answer is:
Viruses are smaller in size ranging from 20-400 nm and bacteria is larger in size, around 1000 nm.

Solution:
The universe originated about 20 billion years ago by a big bang (thermonuclear explosion) of a dense entity. About 4.5 billion years ago, our solar system was probably created when the gaseous cloud called Solar Nebula started to collapse under the force of its own gravity. Founder effect operates in a small population and gene flow operates in a large population. Deep veins are located deep within the muscle tissue and superficial veins are closer to the surface of the skin.

Find the correct match with respect to habitat loss.

Options:
A Plant-pollinator mutualism - Co-extinction
B Extinction of Steller's sea cow - Degradation of habitat by pollution
C Clarias gariepinus - Invasive weed species
D Amazonian rainforests - Deforestation for cultivation of cotton

The correct answer is:
Plant-pollinator mutualism - Co-extinction

Solution:
When a species becomes extinct, the plant and animal species associated with it in an obligatory way also become extinct. When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate. Another example is the case of a coevolved plant-pollinator mutualism where extinction of one invariably leads to the extinction of the other.

Find the correct order of arrangement of ear ossicles from the side of tympanum towards the oval window.

Options:
A Incus → Stapes → Malleus
B Stapes → Incus → Malleus
C Malleus → Incus → Stapes

Find the correct statement.

Options:
A Ori means origin of transcription
B Some bacterial cell may have copy number of plasmids vary from 15-100
C Vector should have many recognition sites for commonly used restriction enzymes so that alien DNA can attach to any one of the sites easily.
D tetR gene in pBR322 can be cleaved by Pvu I and Pst I.

The correct answer is:
Some bacterial cell may have copy number of plasmids vary from 15-100

Solution:
Vectors in biotechnology process is a carrier for the genetic material to transfer to the desired organism's genome. Vectors are also used for making copies or clones. Origin of replication (ori) in a vector enable replication of the vector and vector supporting higher copy number is preferred. Some bacteria have been known to have copy number of plasmids from 15-100. Vector having a selectable marker is preferred as it will help in identifying the transformant from non-transformants. Vector with few or single restriction enzyme sites preferred to avoid fragmentation of the DNA sequence and reduce complication of the biotechnological process. Plasmids and bacteriophages are preferred as cloning vectors from transferring gene. pBR322 is one of the most used plasmids which has the tetracycline resistant gene (tetR) which has restriction site for enzyme BamH I.

Find the CORRECT statement.

Options:
A Joints are not essential for all types of movement.
B Joints are point of contact between bones.
C Fibrous joint permit slight degree of movement.
D Saddle joint is present between phalanges.

The correct answer is:
Joints are point of contact between bones.

Solution:
Joints are points of contact between bones, or between bones and cartilages. Force generated by the muscles is used to carry out movement through joints, where the joint acts as a fulcrum. The movability at these joints vary depending on different factors.
These joints can be of three types depending of amount of mobility. These can be fibrous joints that are immovable joints. Example: sutures in skull, cartilaginous joints are slightly movable joints. Saddle joint is found between carpal and metacarpal of thumb.

(Given that E°cell=1.05 V, 2.303 RTF=0.059 at 298 K)

Options:
A 1.385 V
B 0.9615 V
C 1.05 V
D 1.0385 V

The correct answer is:
0.9615 V

Solution:
Given reaction: Ni(s)+2Ag+(0.001 M)→Ni2+(0.001M)+2Ag(s)

Applying Nernst equation we have:
Ecell=Ecell0-2.303 RTnFlogNi2+[Ag]Ag+2[Ni]
Active mass of solid is taken to be unity so Nis=Ags=1
Ecell=Ecell0-0.059nlogNi2+Ag+2
=1.05-0.05912log0.0010.0012
=1.05-0.0295 log(1×103)
=1.05-0.0295 ×3
=0.9615 V

Therefore, the emf of the cell is 0.9615 V.

Find the enthalpy of dissociation of H2C2O4 from the given data:
Enthalpy of neutralisation of strong acid and strong base is -13.7 kcal mol-1 and that of oxalic acid by a strong base is -25 kcal mol-1.

Options:
A -11.3 kcal mol-1
B 2.4 kcal mol-1
C 1.2 kcal mol-1
D 11.7 kcal mol-1

The correct answer is:
2.4 kcal mol-1

Solution:
One equivalent of oxalic acid gives two moles of H+ ions, as the basicity of the acid is two.

Now enthalpy of neutralisation is defined for one equivalent of acid as well as base.

For weak acids:

Enthalpy of neutralisation=Basicity×enthalpy of neutralisation for strong acid and base+enthalpy of dissociation

Thus, enthalpy of dissociation for oxalic acid=-25-2×-13.7=27.4-25=2.4 kcal mol-1

B Vagina: Lined internally by glands that are shed during menstruation
C Fundus: Common site for implantation
D Cervix and vagina: Birth canal

The correct answer is:

A vaginal wall is made of an internal mucosa, muscular layer, and an outer adventitia. Its mucous membrane is the non-keratinized stratified squamous epithelium. Glands are absent. However, cervical glands do pass on some mucus into it during ovulation. The vaginal orifice is partially covered by an annular centrally perforate membrane called the hymen.
