CSIR UGC JRF NET June 2015, Notification: For Junior Research Fellowship (JRF) & Eligibility for Lectureship (NET)


CSIR JRF NET Life Sciences June 2015 Notification

CSIR will hold the Joint CSIR-UGC Test Tentatively on 21st June, 2015 for determining the eligibility of the Indian National candidates for the award of Junior Research Fellowships (JRF) NET and for determining eligibility for appointment of Lecturers (NET) in certain subject areas falling under the faculty of Science & Technology. The award of Junior Research Fellowship (NET) to the successful eligible candidates will depend on their finding admission/placement in a university/ national laboratory/ institution of higher learning and research, as applicable.

A candidate may apply either for ‘JRF’ or for ‘Lectureship’ (LS) only. He/she may indicate his/her preference in the Online Application, as the case may be. CSIR may consider candidates for ‘JRF’, or ‘Lectureship only” depending on number of fellowships available & performance in the test subject to the condition that they fulfill the laid down eligibility criterion. If a candidate is found to be over-age for JRF (NET) he/she will automatically be considered for Lectureship (NET) only, except for Engineering Sciences.

Engineering Sciences candidates will only be eligible for CSIR JRF ship and are advised to opt for JRF only in the application form. Candidates with M.Sc. qualification or under M.Sc.  Result Awaiting (RA) category shall be eligible for LS in the subjects except Engineering Sciences, subject to the eligibility criteria as laid down by the UGC.

CSIR JRF NET Life Sciences December 2014 Question Paper & Answer Key with Explanations (1)

CSIR/JRF/NET: Life Sciences, December 2014 (II):
Part B (Original Questions)


New: NET Life Sciences Dec 2015 Question Paper with Detailed Answer key

(1). Chirality of DNA is due to:

a. The bases
b. Base stacking
c. Hydrogen bonds between bases
d. Deoxyribose

Ans: d – Deoxyribose

Biomolecules like DNA, proteins, amino acids and sugars are chiral molecules.

(2). Proton motive force during oxidative phosphorylation is generated in mitochondria by:

a. Exchanging protons for sodium ions
b. Pumping protons out into inter-membrane space
c. Pumping hydroxyl ions into the mitochondria
d. Hydrolysis of ATP

Ans: c – Pumping protons out into inter-membrane space

During Electron Transport System (ETS) in the inner mitochondrial membrane, protons are pumped out of the mitochondrial matrix in to peri-mitochondrial space. This creates a concentration gradient of H+ ions between mitochondrial matrix and peri-mitochondrial space to have a proton-motive force. This proton-motive force will be later utilized by the ATP synthase enzyme to synthesize ATP. In chloroplasts, during light reaction of photosynthesis, the proton-motive force is created between inner thylakoid space and chloroplast matrix. Here also this proton-motive force will be later used by ATP synthase to produce ATP.

Chemiosmotic theory: (proposed by Peter Mitchel, 1961): Free energy of electron transport is conserved by pumping H+ from the mitochondrial matrix to the inter-membrane space to create an electrochemical H+ gradient across the inner mitochondrial membrane. The electrochemical potential of this gradient is harnessed to synthesize ATP

(3). In proteins, hydrogen bonds forms as follows: Donor (D)-H— Acceptor (A). Hydrogen bond is more favourable if the angle between D-H and A is:

Revised Rate of CSIR, ICMR and DBT Junior/Senior Research Fellowship (JRF/SRF) and Salary of Research Associates (RA)


A Delicious Diwali Gift for Blooming Scientists in India

In order to encourage science research scholars across India, The Ministry of Science and Technology, Government of India, has announced a Fellowship Hike of about 50% in the amount of various categories of young researches such as Junior Research Fellowship (JRF), Senior Research Fellowship (SRF) and Research Associate (RA). The revised fellowship amount will be as follows (previous rates in brackets)

Junior Research Fellowship (JRF)               : Rs. 25,000.00/- + 30%HRA* (Rs. 16.000/-)

Senior Research Fellowship (SRF)               : Rs. 28,000.00/- + 30%HRA* (Rs. 18,000/-)

Research Associate Category I (RA-I)         : Rs. 36,000.00/- + 30%HRA* (Rs. 22,000/-)

Research Associate Category II (RA-II)      : Rs. 38,000.00/- + 30%HRA* (Rs. (23,000/-)

Research Associate Category III (RA-III)    : Rs. 40,000.00/- + 30%HRA* (Rs 24,000/-)

The revised rate will take effect from 01/10/2014.

* Percentage of HRA varies with the norms of host institutions

Why the pH of water is 7

Biochemical Principle Behind pH Scale and pH of Water
(The Relationship Between Equilibrium Constant, Ion Product of Water and pH Scale)


pH is defined as the negative logarithm of hydrogen ion concentration in a medium. For example, if you are saying a solution with pH 6.5, it means that the concentration of H+ ions in that solution expressed in negative logarithmic term is 6.5. pH is a scale, a scale to measure the H+ ion concentration in a medium. The pH scale starts from 0 to 14. The middle value in the scale (7) is considered as a neutral pH and any solution with pH below 7 is considered as acidic pH. Similarly any solution with pH above 7 is considered as a basic solution. Like the Celsius temperature scale, the pH scale is also constructed on the basis of water, the universal solvent and also the solvent of life.

pH of water is 7 and it is considered as a neutral pH. The term neutral does not mean that water does not contain H+ ions. In fact the term neutral means water contains equal number of H+ and OH- ions. Everyone knows that the pH of water is 7 and it is a neutral pH. But people often forgot to think why the pH of water is 7; from where the value 7 comes… is it a randomly assigned value to water? No, not at all.., the value 7 is an absolute value derived from the ion product of water. The ion product (the product of ions in water i.e., product of H+ and OH-) of water thus forms the basis of pH scale. The video tutorial explains how water got the pH value 7 and how the ion product of water is related to pH scale.
