DNA Gyrase And Topo NM From Mycobacteria : Insights into Mechanism And Drug Action
(2017-10-26)Maintenance of a topological homeostasis by introduction and removal of the supercoils to relieve excessive strain on the DNA is a hallmark of topoisomerase function in the cell. The requirement of the topoisomerases during ... -
Fire Ecology of a Seasonally Dry Tropical Forest in Southern India
(2017-10-26)Fire ecology encompasses the study of the factors, biotic and abiotic, that influence the occurrence of fire in an area, as well as the effects fire has on the flora and fauna native and non-native to the region (Whelan ... -
Insights into an Evolutionary Radiation : Causes And Consequences of Diversification in the Western Ghats Bush Frogs
(2017-10-26)One of the biggest attractions of the tropics is its stunning diversity; the origin and determinants of this diversity are amongst the most important questions in evolution and biogeography. There are two ways of looking ... -
Evaluation of Alternate DNA Structures at c-MYC Fragile Region Associated with t(8;14) Translocation And Role of GNG Motifs During G-quadruplex Formation
(2017-10-11)Watson-Crick paired B-form DNA is the genetic material in most of the biological systems. Integrity of DNA is of utmost importance for the normal functioning of any organism. Various environmental factors, chemicals and ... -
Isolation And Identification of Tropane Alkaloid Producing Endophytic Fungi from Datura Metel L., And Studies on Colletotrichum Boninense Recombinant Putrescine N-mehtyltransferase
(2017-10-11)Datura metel is a herbaceous plant found in almost all tropical parts of the world. It belongs to the family Solanaceae whose members, viz. Duboisia, Atropa, Hyoscyamus and Datura plants are known to produce tropane ... -
Exploring the Evolution of Cellobiose Utilization in Shigella Sonnei And the Conservation of ChbG Orthologs in Eukaryotes
(2017-10-11)The chb operon constitutes the genes essential for utilization of chitooligosaccharides in Escherichia coli and related species. The six genes of the operon code for a transcriptional regulator (ChbR) of the operon, a ... -
Role of Chemokine Receptor, CXCR4 Mediated Signaling in Cellular Senescence
(2017-10-05)Cellular senescence has been proposed to be equivalent to organismal aging and is one of the outcomes of the cell fate decision process in response to DNA damage that occurs in cells. When a cell encounters DNA damage, the ... -
Acoustic Signals, Mate Choice And Mate Sampling Strategies in a Field Cricket
(2017-10-05)Acoustic communication in orthopterans and anurans provides a suitable model system for studying the evolutionary mechanisms of sexual selection mainly because males use acoustic signals to attract females over long distances ... -
Role of CG9650 in Neuronal Development And Function of Drosophila Melanogaster
(2017-10-05)The nervous system is the most complex system in an organism. Functioning of the nervous system requires proper formation of neural cells, as well as accurate connectivity and signaling among them. While the major events ... -
Physiological And Exogenous Means of Regulating DNA Damage Response : Insights into Mechanisms of DNA Repair And Genomic Instability
(2017-09-23)Maintenance of genomic integrity with high fidelity is of prime importance to any organism. An insult which may result in compromised genome integrity is prevented or its consequences are monitored by advanced cellular ... -
Sequence And Structural Determinants of Helices in Membrane Proteins
(2017-09-23)Membrane proteins roughly constitute 30% of open reading frames in a genome and form 70% of current drug targets. They are classified as integral, peripheral membrane proteins and polypeptide toxins. α-helices and β -strands ... -
Investigating Pattern Recognition And Bi-coordinate Sound Localization in the Tree Cricket Species Oecanthus Henryi
(2017-09-20)Acoustic communication, used by a wide variety of animals, consists of the signaler, the signal and the receiver. A change in the behaviour of the receiver after reception of the signal is a prerequisite for communication. ... -
The Structure And Function Of The Vocal Repertoire Of The Greater Racket-Tailed Drongo (Dicrurus paradiseus) : Insights Into Avian Vocal Mimicry
(2017-07-12)Sound is used as a medium for communication by taxa as varied as insects, fish, amphibians, birds and mammals. In some birds like the suboscines, song is genetically encoded, whereas in parrots, hummingbirds and oscines, ... -
Mate Choice, Mate Sampling And Baffling Behaviour In The Tree Cricket Oecanthus henryi
(2017-07-12)Among the different sensory modalities that play a role in sexual selection, acoustic communication plays an important one. Acoustic communication has been known to be used for male-male competition (territory maintenance, ... -
Sexual Selection On Elephant Tusks
(2017-06-12)Darwin was troubled by elaborate male traits observed in many species that are seemingly maladaptive for survival, the peacock’s tail being the most iconic of all. He wrote "The sight of a feather in a peacock’s tail, ... -
Study Of Rpb4, A Component Of RNA Polymerase II As A Coordinator Of Transcription Initiation And Elongation In S. Cerevisiae
(2017-05-24)RNA polymerase II (Pol II) is the enzyme responsible for the synthesis of all mRNAs in eukaryotic cells. As the central component of the eukaryotic transcription machinery, Pol II is the final target of transcription ... -
Insights Into Cytostatic Mechanisms Regulated By Receptor Guanylyl Cyclase C
