  • What are Plasmodesmata?
    Life Sciences - 12 Sep 2024
    One of the most fundamental differences between animal and plant cells is the cell wall – a rigid structure surrounding the plant cells. The cell wall provides strength and structural support, but it...
  • What are Ribozymes?
    Life Sciences - 24 Jul 2023
    A ribozyme is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The ribozyme catalyses specific reactions in a similar way to that of protein enzymes.
  • What is MicroRNA?
    Life Sciences - 22 Jul 2023
    Gene expression in cells and tissues of every complex organism is precisely controlled and largely dependent on different conditions (such as development, changes in the environment, diseases or...
  • RNA Synthesis
    Life Sciences - 22 Jul 2023
    RNA is usually synthesized from DNA. The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand is used as a template or guide on which the RNA is formed. Since RNA forms...
  • Ribozyme Activity
    Life Sciences - 20 Jul 2023
    Ribozymes are RNA molecules that are capable of catalyzing a chemical reaction. Ribozymes occur naturally inside cells where they play an essential role in the ribosome, joining amino acids together...
  • Telomere Lengthening
    Life Sciences - 20 Jul 2023
    To circumvent active DNA damage pathways that are prompted by critically short telomeres, cells must contend with the loss of telomere repeats due to various causes either by copying repeats using...
  • MicroRNA Nomenclature
    Life Sciences - 20 Jul 2023
    MicroRNAs (miRNAs) are evolutionary conserved small non-coding RNA molecules that post-transcriptionally regulate gene expression by base-pairing to mRNAs. Recent evidence shows that miRNA-mediated...
  • Capillary Electrophoresis
    Life Sciences - 20 Jul 2023
    Although it may seem intricate at a first glance, capillary electrophoresis is an instrumental technique with very simple principles. Minute capillaries are used for the electro-kinetic separation of...
  • Magnetic Particle Imaging (MPI) Applications in Medicine
    Life Sciences - 20 Jul 2023
    Magnetic particle imaging (MPI) represents a tomographic imaging method that is used to determine the spatial distribution of magnetic material injected into the bloodstream. Iron-oxide based...
  • Tube Formation Assay: an Introduction
    Life Sciences - 19 Jul 2023
    Angiogenesis, which denotes the process of developing new blood vessels from preexisting ones, is a vital event for embryonic development, organ growth and wound healing. Newly created blood vessels...
