Classification of Fungi Fungi include eukaryotic microorganisms. They might appear as moulds, yeasts, or a hybrid of the two. Some fungi have the potential to lead to systemic, cutaneous, subcutaneous, autoimmune, or allergy disorders. Yeasts are tiny fungi made up of single cells that divide by budding. In contrast, hyphae, which are lengthy filaments that …
Prokaryotes Vs Eukaryotes Overview Prokaryotes Definition Prokaryotes are primordial single-celled organisms that lack additional organelles and a membrane-bound nucleus, making them primitive in both structure and function. The terms “pro” and “karyon,” which mean “nucleus” in Greek, are combined to form the word “prokaryote.” As the most basic form of life, prokaryotes are regarded as the …

Incomplete Dominance Vs Co-Dominance Overview Incomplete dominance definition When the dominant allele does not completely suppress the expression of the recessive allele’s phenotype, incomplete dominance develops, giving rise to an intermediate phenotype in the heterozygote. Due to the phenotype’s mixture of dominant and recessive genes, incomplete dominance is also known as partial dominance or semi-dominance. …

Autotroph Vs Heterotroph Overview Autotroph Definition An organism group that can produce its own sustenance using elements such as water, sunshine, air, and other compounds is known as an autotroph. The terms “auto” and “troph,” which imply food and self-respectively, make up the word “autotroph.” Thus, autotrophs are able to produce their own nourishment on …

Lineweaver–Burk Plot Overview The Lineweaver-Burk equation of enzyme kinetics is represented graphically by the Lineweaver-Burk Plot (also known as the double reciprocal plot), which was first introduced by Dean Burk and Hans Lineweaver in 1934. It is difficult to predict Vmax and, consequently, Km from a hyperbolic plot since Vmax is reached at an infinite …
Centrioles Definition Near the nucleus, eukaryotic cells have two centrioles, which are two cylindrical, rod-shaped microtubular structures. They are present in the majority of mammalian cells, moss cells, certain fern cells, and most algal cells, with the remarkable exception of red algae. They do not have DNA or RNA or a limiting membrane. Prokaryotes, red …

What is Ziehl-Neelsen staining? Originally created by Ziehl and then improved by Neelsen, the Ziehl-Neelsen staining method is a differential staining method; therefore, the name Ziehl-Neelsen stain. Neelsen created the Ziehl-Neelsen Staining Technique by heating carbol-fuschin from Ziehl’s experiment, adding a decolorizing agent made of acid-alcohol, and a counter stain made of methylene blue dye. …

Objectives of the Methyl Red (MR) Test Based on the generation of acid, to distinguish between two primary categories of facultative anaerobic enteric bacteria. Using a mixed-acid fermentation of glucose, it assesses the bacterial ability to produce stable acid end products. Principle of Methyl Red (MR) Test The MR test, also called the methyl red test, is …
