The Elucidation of the Mechanism of Meiotic Chromosome Synapsis in Saccharomyces Cerevisiae : Insights into the Function of Synaptonemal Complex, Hop1 and Red1, Proteins and the Significance of DNA Quadruplex Structures
(2017-12-03)Meiosis is a specialized type of cell division where two rounds of chromosome segregation follow a single round of DNA duplication resulting in the formation of four haploid daughter cells. Once the DNA replication is ... -
Unique Response and the Survival Mechanism of Mycobacterial Subpopulations against Oxidative and Nitrite Stress
(2017-12-03)Mycobacterial populations are known for the heterogeneity in terms of cell size, morphology, and metabolic status, which are believed to help the population survive under stress conditions. Such population heterogeneity ... -
Identification, Structural and Functional Characterisation of the Molecule that Induces Asymmetric Cell Division in Mycobacteria
(2017-12-03)Phenotypic heterogeneity in terms of cell size, morphology, and metabolic status, which are believed to help the population survive under stress conditions, is known in mycobacterial populations. Such population heterogeneity ... -
Delineating the Role of OsMADS1 in Auxin Distribution, Floret Identity and Floret Meristem Determinacy
(2017-12-02)Rice have highly derived florets borne on a short branch called ‘spikelet’ comprised of a pair of rudimentary glumes and sterile lemma (empty glumes) that subtends a single fertile floret. The floral organs consist of a ... -
Structural and Functional Studies on Pyridoxal 5′-Phosphate Dependent Lyases and Aminotransferases
(2017-11-30)The thesis describes structural and functional studies of two PLP-dependent enzymes, diaminopropionate (DAP) ammonia lyase (DAPAL) and N-acetylornithine aminotransferase (AcOAT). The main objective of this work was to ... -
Understanding Functions for Fission Yeast Pre-mRNA Splicing Factors SpPrp18 and SpSlu7 in Constitutive and Alternative Splicing
(2017-11-29)Exonic sequences of eukaryotic genes are interspersed with introns which when accurately removed from the primary transcript (pre-mRNA) results in a functional transcript. These splicing reactions are carried out by the ... -
Elucidating the Roles of Lon Protease and its Substrate, MarA, in Response to salicylate and other Compounds in Escherichia coli
(2017-11-28)Cytosolic protein degradation is crucial for cellular homeostasis as it orchestrates protein turnover by destruction of misfolded, unstable and abnormal proteins. This process has two main stages: (i) an ATP-dependent stage ... -
Studies on Molecular Targets and Pathways Regulated by Rice RFL for Flowering Transition and Panicle Development
(2017-11-28)LFY of Arabidopsis is a member of a unique plant specific transcription factor family. It is involved in giving meristem a determinate floral fate by the activation of floral organ identity genes and preventing inflorescence ... -
Structural Studies on Mycobacterium Tuberculosis Peptidyl-tRNA Hydrolase and Ribosome Recycling Factor, Two Proteins Involved in Translation
(2017-11-27)Protein synthesis is a process by which organisms manufacture their proteins that perform various cellular activities either alone or in combination with other similar or different molecules. In eubacteria, protein synthesis ... -
Host Gene Expression Profiling of Japanese Encephalitis Virus Infected cells : Identification of Novel Pro- and Anti-viral Genes
(2017-11-27)Japanese encephalitis virus (JEV), a mosquito-borne flavivirus is the causative agent of Japanese encephalitis (JE). The disease affects mostly children and around 30000– 50000 cases of JE and up to 15000 deaths are reported ... -
How Much Initiator tRNA Does Escherichia Coli Need?
(2017-11-27)The work discussed in this thesis deals with the significance of initiator tRNA gene copy number in Escherichia coli. A summary of the relevant literature discussing the process of protein synthesis, ... -
Modelling Spatial Patterns of Landsacape Dynamics
(2017-11-23)Landscape is a heterogeneous collection of visibly distinct features of various elements of land and its various forms on the earth surface. Its pattern is subjected to disturbances and undergo rapid alterations in its ... -
Emergence and Homeostasis of Functional Maps in Hippocampal Neurons
(2017-11-23)Systematic investigations through several experimental techniques have revealed that hippocampal pyramidal neurons express voltage gated ion channels (VGICs) with well-defined gradients along their dendritic arbor. These ... -
The Dynamics of Iron in Miniferritins : A Structure-Function Connection
(2017-11-23)The DNA binding proteins under starvation (Dps) from M. smegmatis are cage-like structures which internalize iron and bind DNA. They provide resistance to the cells from free radical damage, and physically protect the DNA ... -
Mechanism of Abrin-Induced Apoptosis and Insights into the Neutralizing Activity of mAb D6F10
(2017-11-23)Abrin is a potent toxin obtained from the seeds of Abrus precatorius. It is a heterodimeric glycoprotein consisting of an A and a B subunit linked together by a disulfide bond. The toxicity of the protein comes from the A ... -
