In species-area relationships equation - log S = log C + Z log A
'Z' denotes the -

The reasons why not both the strands of DNA are copied during transcription are:
(A) Replication fork will not be formed
(B) The two RNA molecules synthesised will form dsRNA molecule
(C) Complicate the genetic information transfer machinery
(D) dsRNA molecule will not be translated into proteins

Read the given passage carefully and answer the questions
Antibiotics have greatly improved our capacity to treat deadly diseases such as plague, whooping cough (kali khansi), diphtheria (gal ghotu) and leprosy (kusht rog), which used to kill millions all over the globe.
Streptokinase produced by the bacterium Streptococcus and modified by genetic engineering is used as a 'clot buster' for removing clots from the blood vessels of patients who have undergone myocardial infarction leading to heart attack. Microbes are diverse-protozoa, bacteria, fungi and microscopic animal and plant viruses, viroids and also prions that are proteinacious infectious agents. The puffed-up appearance of dough is due to the production of CO₂ gas. Similarly the dough, which is used for making bread, is fermented using baker's yeast (Saccharomyces cerevisiae). Primary sewage treatment basically involve physical removal of particles - large and small from the sewage through filtration and sedimentation. These are removed in stages; initially, floating debris is removed by sequential filtration. Then the grit (soil and small pebbles) are removed by sedimentation. All solids that settle form the primary sludge, and the supernatant forms the effluent. The effluent from the primary settling tank is taken for secondary treatment. The primary effluent is passed into large aeration tanks, where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs. While growing, these microbes consume the major part of the organic matter in the effluent.
Prions are made up of :

Match List-l with List-ll

List-l (Evolutionary stages of man)	List-II (Features)
(A) Dryopethicus	(I) Brain capacity 900 cc
(B) Australopithecines	(II) Hairy and walked like gorillas
(C) Homo habilis	(III) Brain capacity 650-800 cc
(D) Homo erectus	(IV) Lived in east African grasslands

Which one of the following techniques is used for the separation of DNA fragments?

If \(A^{-1}\) exists for the matrix \(A=\left[\begin{array}{ccc}1 & \lambda & -1 \\ -1 & 1 & 0 \\ \lambda & 1 & 1\end{array}\right]\) then

The vector through which dengue and chikungunya spread is:

If A is a square matrix such that \(A^2=A\) and I is the identity matrix of the same order as A, then \((I+A)^2-3 A\) is equal to

The sequencing of fragments using automated DNA sequencers in HGP, worked on the principle of the method that was developed by:
