Definition of Anaphase This is the phase in which the two identical daughter cells are separated from duplicate genetic components carried in the nucleus of the parent cell. The sister chromatids (replicated chromosomes) are oriented along the cell’s equator on the metaphase plate in the preceding phase, metaphase. As a result, each pair of chromosomes … Read more
Metaphase Definition Metaphase is a cell cycle stage that occurs during both mitosis and meiosis cell division. The chromosomes condense during metaphase in mitosis and meiosis, and they become visible and identifiable during alignment at the centre of the dividing cell, forming a metaphase plate at the cell’s centre. A set of checkpoints ensure that … Read more
Primary Succession Definition Primary succession is a type of ecological succession that occurs in a newly formed ecosystem that lacks habitable soil, but is then colonised by living creatures for the first time. A series of events that occur in order to build a stable ecosystem is known as primary succession. Natural phenomena such as … Read more
The Golgi apparatus has multiple names such as Golgi complex or Golgi body. The name is given on the name of the scientist, who discovered the organelle, i.e. Camillo Golgi. It is found in all the eukaryotic cells, plants as well as animals. They are membrane-bound organelle present in the cytosol of the cell. Let us … Read more
Intron Definition Introns are non-coding DNA sequences within a gene that are removed by RNA splicing during maturation of the RNA product. The term ‘intron’ refers to the intragenic region which is present within a gene. ‘introns’ as a term indicates both the DNA sequences within the gene and the corresponding sequence in RNA transcripts. … Read more
What is Bile Solubility Test ? The bile solubility test is a biochemical test used to distinguish Streptococcus pneumoniae from other alpha-hemolytic Streptococci and to confirm the diagnosis. The bile solubility test has been utilised as a critical test for S. pneumoniae differentiation because it enables for the difficult work of distinguishing between the two … Read more
Plants and animals are built up of millions of cells, each with its own set of characteristics. A significant aspect that defines their modes of multiplication is that they are both eukaryotic cells, which means they have a genuine nucleus that is enclosed and separated from other organelles by a nuclear membrane. Plant Cell Diagram … Read more
Cytoplasm Description In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are: Cytosol (a gel-like substance). The organelles (the … Read more
What is Butyrate Disk Test ? The capacity of Moraxella catarrhalis to use bromochloro-indolyl butyrate or 4-methylumbelliferyl butyrate is used in the butyrate disc test, which is a quick identification test for Moraxella catarrhalis. Otitis media, sinusitis, conjunctivitis, bronchitis, and pneumonia are all caused by Moraxella (Branhamella) catarrhalis. Furthermore, many M. catarrhalis strains develop the … Read more
What is Beta Lactamase Test ? The chromogenic cephalosporinase test is one of the most important tests in clinical laboratories for β – lactamase detection. The substrate is chromogenic cephalosporin, while the test disc is chromogenic cephalosporin. When organisms with β -lactamases are put to the disc, they work by opening the substrate’s β -lactam … Read more
