Viroids Feature Virus Viroid Genetic Material DNA or RNA, single- or double-stranded, linear or segmented Small circular single-stranded RNA molecule Capsid/Coat Protein coat (capsid); some have additional lipid … Read more
What is Northern blotting? Northern blotting is a technique in molecular biology that allows for the detection of specific RNA sequences in a complex mixture, offering valuable insights into gene expression patterns. In 1977, James Alwine, David Kemp, and George Stark at Stanford University introduced a method that was cleverly named “Northern blot,” referencing … Read more
Southern Blotting is a molecular biology technique used for the identification of a specific DNA sequence in a collected DNA sample.
Your body is currently doing a lot of things simultaneously. Your body is sending electrical impulses, pumping blood and filtering urine.
Gram-negative bacteria are a diverse group of microorganisms known for their unique cell structure, which plays a key role in how they interact with the environment and cause infections. Unlike Gram-positive bacteria, Gram-negative bacteria have a thin peptidoglycan layer sandwiched between two membranes. The outer membrane contains lipopolysaccharides (LPS), which can trigger strong immune responses … Read more
Gram-positive bacteria are a group of bacteria classified based on how they react to a lab test called the Gram stain. When stained, these bacteria hold onto a purple dye because of their thick, mesh-like cell wall made of peptidoglycan. This sturdy layer acts like a protective shield, unlike Gram-negative bacteria, which have thinner walls … Read more
What is Fine Adjustment Knob? Particularly in high magnification levels, the fine adjustment knob is an essential part of a microscope as it helps to achieve exact and crisp focus. Particularly in the study of cells, microscopes are essential instruments in scientific inquiry as they let us view objects beyond our human sight. Under a … Read more
It is designed in a way that is compact and portable which is why it’s called a pocket’. They’re pocket-sized however some are bigger. Their size is not enough to be able to hold a mirror in order to put the image in the proper place. However, they contain a small stage where one can place an object to observe. They’re portable so that they can be utilized by both professionals and amateurs according to the task they’re designed to fulfill.
What is transmission electron microscope? A transmission electron microscope (TEM) is an electron microscope that transmits electrons through a sample to observe it. Scientists use transmission electron microscopes to analyze materials and examine their microstructural and compositional properties. A transmission electron microscope transmits a highly focused beam of electrons through a sample to observe and … Read more
This reflects the seemingly marvelous developments that have occurred from the history of microbiology to the present day. Advances in technology and subsequent research in the field over the years have meant that once we learned how to study these tiny creatures, we only grew in appreciation for these vital little agents. But in 1590, … Read more
