Difference Between Genomics and Proteomics

Difference Between Genomics and Proteomics

Difference Between Genomics and Proteomics Genomics and proteomics are closely-related fields. The main difference between genomics and proteomics is that genomics is the study of the entire set of genes in the genome of a cell whereas proteomics is the study of the entire set of proteins produced by the cell. S.N. Character Genomics Proteomics 1.       Definition Genomics is … Read more Difference Between Genomics and Proteomics

Differences between cilia and flagella

Differences between cilia and flagella

Differences between cilia and flagella Cilia and flagella are cytoplasmic processes extending from the cell surface. The cell organelles are similar but are differentiated based on their size, number, function and/or mode of beating. S.N. Character Cilia Flagella 1.       Definition Cilia are short, hair like appendages extending from the surface of a living cell. Flagella are long, threadlike appendages … Read more Differences between cilia and flagella

Differences between O Antigen and H Antigen

Differences between O Antigen and H Antigen

Differences between O Antigen and H Antigen The surface structures of bacteria have considerable antigenic heterogeneity. Often these antigens are used as part of a serologic classification system for the bacteria. The classification of the 2000 or so different Salmonellae is based principally on the types of the O (LPS side chain) and H (flagellar) … Read more Differences between O Antigen and H Antigen

Differences between Plasmodium vivax and Plasmodium falciparum

Differences between Plasmodium vivax and Plasmodium falciparum

Differences between Plasmodium vivax and Plasmodium falciparum Five species of Plasmodium are believed to cause malaria in humans: Plasmodium vivax, P. falciparum, P. malariae, P .ovale and P. knowlesi.  Of the five species that infect humans, P. vivax and P. falciparum cause 95% of the total infections. S.N. Character Plasmodium vivax Plasmodium falciparum 1. Disease Caused … Read more Differences between Plasmodium vivax and Plasmodium falciparum

Differences between Anthrax bacilli and Anthracoid bacilli

Differences between Anthrax bacilli and Anthracoid bacilli

Differences between Anthrax bacilli and Anthracoid bacilli The saprophytic organisms which simulate the anthrax bacillus closely, both in their morphological and cultural characters within the group of Gram-positive aerobic sporing bacilli are termed as Anthracoid bacilli. They have a general resemblance to anthrax bacilli such as producing dry wrinkled colonies and in the smear, appearing … Read more Differences between Anthrax bacilli and Anthracoid bacilli

Differences between Enzymes and Hormones

Differences between Enzymes and Hormones

Differences between Enzymes and Hormones Enzymes and hormones are bio-genic substances present in all living organisms whose function, formation, secretion and purpose varies in both plants and animals. An enzyme is a highly selective catalyst that greatly accelerates both the rate and specificity of metabolic reactions. A hormone, on the other hand, is a chemical released … Read more Differences between Enzymes and Hormones

Differences between DNA Replication and Transcription

Differences between DNA Replication and Transcription

Differences between DNA Replication and Transcription DNA replication and transcription are fundamental genetic processes that are essential for cell growth and division.  Both DNA replication and transcription processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in … Read more Differences between DNA Replication and Transcription

Differences between Meningitis and Encephalitis

Differences between Meningitis and Encephalitis

Differences between Meningitis and Encephalitis Meningitis and Encephalitis are the two main kinds of neurological conditions related to the brain and spinal cord, where the layer surrounding the brain or the brain itself gets inflamed. S.N. Character Meningitis Encephalitis 1.       Definition Inflammation of the thin membranes that surround the brain and spinal cord called the meninges (mostly … Read more Differences between Meningitis and Encephalitis

Differences between Light and Electron Microscope

Differences between Light and Electron Microscope

Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects which cannot be seen clearly through an unaided eye. However, each of these microscopes has distinct features and is suitable for different purposes. S.N. Character Light Microscope Electron Microscope 1.       Alternatively known as Optical microscope … Read more Differences between Light and Electron Microscope
