  • Inherited Diseases Caused by Faulty Ion Channels ( 9563 reads)   

    Diseases that are caused by faulty ion channel proteins are termed as channelopathy .Abnormal functioning of ion channels can cause diseases in many tissues. - Category: Genetics
  • Ecotones - The Transitional Zones ( 9540 reads)   

    Ecotone is an interface region between two different ecosystems, for instance a forest and grassland. In the ecology of landscape, an ecotone is the marginal area where 2 patches that have a distinct ecological composition meet. - Category: Biology
  • Mechanisms Involved in the Origin of New Genes ( 2702 reads)   

    Origin of new genes is a driving power for evolution in all living things. The processes that produce new genes, includes a diversity of molecular events, all of which must take place in the germ line to be inherited by the subsequent generation. - Category: Genetics
  • Anatomy of Y-Chromosome and its Associated Disorders ( 3405 reads)   

    The chromosome Y is 1 among the 2 sex chromosomes present in human beings while the other is the X chromosome. The sex chromosomes form 1 of the 23 pairs of human chromosomes in every cell. - Category: Genetics
  • Species Interactions - Interspecific Competition ( 4862 reads)   

    Interspecific competition (Inter refers to, among or between) is one in which members of one species experience a reduction in productiveness, survivorship, or development as a consequence of exploitation of resources or meddling by individuals of a second species. - Category: Biology
  • Indicator Species - Important Monitoring Tools ( 4502 reads)   

    An indicator species is one whose existence, nonexistence, or comparative well-being in a given environment is an indication of the total health of its ecosystem.Indicator organisms are also utilized to analyse food, water or other samples for the likelihood of contamination by microorganisms. - Category: Biology
  • Genomics and Its Applications in Agriculture ( 7452 reads)   

    Agricultural genomics is concerned with the research and development activities in agriculture that have obvious potential to translate genomic technology in agronomic advancement. - Category: Biotech Research
  • Yeast Artifical Chromosomes (YACs) and their Applications ( 10933 reads)   

    YAC is an artificially built chromosome and includes the centromere, telomere and autonomously replicating sequences essential for replication and conservation in yeast cells. - Category: Biotech Research
  • Riftia Pachyptila - The Gaint Tube Worm ( 4533 reads)   

    The giant tube worm (Riftia pachyptila or tubeworm) are animals without a mouth, gut and legs that depend on microorganisms for food.Giant tube worms are seen everywhere in the pacific ocean where deep sea hydrothermal vents have been revealed. - Category: Biology
  • Isochromosomes, Ring Chromosomes and Their Associated Abnormalities ( 5914 reads)   

    An 'isochromosome' is an unusual chromosome with two identical arms, either two short (p) arms or two long (q) arms produced by transverse rather than normal longitudinal splitting of a replicating chromosome.'Ring chromosomes' (denoted as 'r') are the unusual chromosomes in which the end of each chromosome arm (telomere) has been lost and the broken arms have been reunited in the ring formation. - Category: Genetics
  • Lethal Alleles - Its Instances in Humans, Plants and Animals ( 38719 reads)   

    The hint to lethal alleles is a 2:1 phenotypic ratio. This ratio looks different than the typical 3:1 ratio observed, implying the variations of the Mendelian genetics. - Category: Genetics
  • Speciation Types | Formation of New Species ( 3286 reads)   

    What is Speciation? It is a elementary process responsible for the diversity of life. Understanding the common patterns and processes of speciation is fundamental to explaining the diversity of life. - Category: Biology
  • Endosymbiont Theory - About the Origin of Mitochondria and Chloroplast ( 8045 reads)   

    Endosymbiotic theory tries to explicate about the origins of cell organelles of eukaryotes such as mitochondria and chloroplasts. - Category: Biology
  • The Regulation of Cell Cycle ( 2839 reads)   

    The somatic cell cycle also contains 'Gap' phases recognized as G1, which links the end of M phase to beginning of S phase in the next cycle and G2, which set apart the S and M phases. On the basis of environmental and developmental signals cells in G1 may briefly or permanently depart the cell cycle and enter a detained phase known as G0. - Category: Biology
  • Bioluminiscence - Emission of Light From Living Organisms ( 2849 reads)   

    Bioluminiscence is a type of chemiluminiscence where light generating chemical reaction occurs inside an organism (like insects). A wide range of organisms are gifted with the ability to produce light and to exhibit and manage it in a variety of ways - Category: Biotech Research
  • Bio-Insecticide - Beauveria Bassiana and its Use in Agriculture ( 5817 reads)   

    Bioinsecticides are a greatly advantageous alternative to the usual chemically formulated insecticides. Unreasonable selection and application of chemical pesticides led to environmental toxicity of their residues, decrease or loss of efficiency due to the evolution of pathogens, unwanted effects on non-target organisms sharing the ecosystem. Therefore Bio Insecticides like Beauveria bassiana are a greatly advantageous alternative to the usual chemically formulated insecticides. - Category: Agriculture
  • Ribozymes - the Catalytic RNA's ( 3177 reads)   

    RNA molecule that function as enzymes, regularly found to catalyse the cleavage of its own or other RNA's .That is RNA's that act as enzymes are known as Ribozymes - Category: Biotech Research
  • Conservation Biology- to Preserve the Diversity of Animals and Plants ( 3001 reads)   

    It is however within our capacity to alter appreciably the rate at which biotic diversity is damaged and tiny changes in rates can produce huge effects over long periods of time. - Category: Biology
  • Extensions of Mendelian Principles - Inheritance Biology ( 7048 reads)   

    Mendel's laws fail to adequately explain some phenomenon like mitochondrial gene inheritance and inheritance due to linkage between genes on the same chromosome and variation in gene expression and gene interactions can produce results other than phenotypic ratio predicted by Mendel's laws. - Category: Genetics
  • Extrachromosomal DNA - mtDNA and its Various Applications ( 2847 reads)   

    The sequencing of mitochondrial DNA was the first important part of Human Genome Project (mtDNA is double stranded circular DNA about 16569 base pairs long). Mammalian mitochondrial DNA (mtDNA) is solely inherited from the mother. - Category: Genetics
  • Agrobacterium Tumefaciens and Transformation of Plants ( 3215 reads)   

    Despite the many recent developments in plant biotechnology and development of modernised alternative gene transfer techniques such as direct DNA delivery techniques, laser, tissue electrophoration, silicon carbide whiskers etc Agrobacterium tumefaciens still prevail as a oldest and widely used method for plant transformation. - Category: Agriculture
  • Epidemics and Pandemics-Spread of Infectious Diseases ( 3362 reads)   

    Epidemics and pandemics have been known throughout recorded human history. These incidences are less in modern day cities due to better sanitary conditions. Present interconnected world makes it easier for diseases to spread rapidly and over greater distances from the point of origin. Therefore it is important to understand the insights of these maladies for preventing future breakouts. - Category: Healthcare
  • Extremophiles - Organisms Thriving in Harshest of the Environments ( 5846 reads)   

    'Extremophile' is a term that refers to bacteria that are able to grow and sustain in extremely harsh environments when compared to the environments that are termed as favourable for the growth of bacteria. The discovery of extremophiles has increased speculation of chances for bacterial life on planets such as Mars, Europa (moon of Jupiter) and other stellar bodies. - Category: Biology
  • Antibiotic Resistance - Rethinking the Use of Antibiotics ( 2397 reads)   

    One of the most important therapeutic milestones in the medical history is 'antibiotics'. They are natural or synthetic compounds that kill bacteria. Antibiotic resistance is the ability of a microorganism to resist the effects of an antibiotic. It is a problem that develops when antibiotics are overused or misused. - Category: Healthcare
  • Bacillus Thuringiensis (insecticide) - Applications in Agricultural Industry ( 5018 reads)   

    Application of Bacillus thuringiensis as an insecticide and Bt transgenic plants in agriculture. - Category: Agriculture
