Little, single-celled creatures living practically everywhere are bacteria. They’re prokaryotic, meaning they lack a real nucleus. They differ from eukaryotic cells in that they lack membrane-bound organelles. Shapes vary; spherical (cocci), rod-like (bacilli), spiral (spirilla), or comma-shaped (vibrios). Their survival in hostile environments depends on this diversity. Some twist like corkscrews, designated as spirochaetes. There … Read more
What is Semiconductor Sequencing? Semiconductor sequencing is the integration of microchip technology with DNA sequencing where electrical signals replace the detection of light. This sequencing method is unique because it uses complementary metal-oxide semiconductor chips associated with sequencing by synthesis chemistry; so, in this respect, it opens up opportunities to make DNA analysis quicker and … Read more
A trinocular microscope can define as a specialized Light-Microscopy instrument that adds a third optical tube for imaging or recording purpose’s, and this design is widely used in laboratory Observation’s where detailed visualization of micro-structures are needed. It is important to note that the three-tube arrangement give’s a look into how researchers try to observe … Read more
Rickettsia is a small, Gram-negative, obligately intracellular bacterium. It is the organism which can grow and multiply only inside the living host cell. It is highly specialized bacteria showing extreme genomic reduction. Due to this, many metabolic pathways are absent and the bacteria is unable to synthesize its own energy. It depends on the host … Read more
What is cryo-EM? Principle of cryo EM Types of cryo EM Cryo-electron microscopy (cryo-EM) is a collection of special methods. These are broadly categorized into two types, mainly cryo-transmission electron microscopy (cryo-TEM) and cryo-scanning electron microscopy (cryo-SEM). Each has its own advantage in the analysis of biological samples in their native state, frozen by cryo-preparation. … Read more
What is Theta model of DNA Replication? The theta model of DNA replication is a mechanism for DNA replication which occurs in circular DNA molecules, in particular, those of bacteria, and also the mitochondria and chloroplasts. True to its name, this replication process creates an intermediate structure during replication that resembles the Greek letter theta … Read more
Epi-Fluorescence Microscopy is defined as an optical imaging method, which is employed in laboratories for visualization of fluorescent-labeled samples. The technique is widely described as an essential approach, and it has been repeatedly applied in cell studies, tissue examinations, and even in material analysis. In this method, illumination is delivered from the same side / … Read more
What is Telomerase? Telomerase (terminal transferase) is a ribonucleoprotein enzyme that extends telomeres, the repetitive nucleotide sequences at the ends of eukaryotic chromosomes. Telomeres function as protective caps, stopping chromosome ends from being erroneously perceived as DNA damage or from bonding with neighboring chromosomes. Most eukaryotes use telomerase to maintain their telomeres, but some organisms, … Read more
What Are Telomeres (telomere)? At the ends of linear eukaryotic chromosomes are specialized structures called telomeres. DNA degradation is prevented by repetitive nucleotide sequences of the telomere, which caps and so stabilizes chromosomal DNA during cell division. The termini of chromosomes not only have no translation product but instead have a highly important role in … Read more
What is Gluconeogenesis? Gluconeogenesis Definition Gluconeogenesis is a metabolic process that synthesizes glucose from non-carbohydrate precursors, such as lactate, glycerol, and amino acids, primarily in the liver and kidneys, to maintain blood glucose levels during fasting or low carbohydrate intake. Location of Gluconeogenesis – Where does Gluconeogenesis Occur? Gluconeogenesis primarily occurs in the liver, which … Read more
