GENETICS Field of biology in which we study about Heredity, genes, genetic variations in organisms. The process of Passing genes from parents to children is known as heredity. Every child inherits genes from both biological parents. Genetic terminology: Trait any characteristic which can be passed from parent to progeny are known as traits. Heredity passing […]
Category: Biology
Biology is the study of all living things. In this field of science, we study the functioning of the body, different cells, and organisms.This field is further divided into many other fields such as Bioinformatics, Biochemistry, biotechnology, microbiology.
Cells of Lymphoid Lineage
Cells of Lymphoid lineage include T, B, and NK(natural killer) cells, and among these B and T cells are the part of Adaptive immune response while NK cells are the part of innate immune responses. These cells(B and T) contains a large nucleus and a thin layer of cytoplasm. B cells B cells also are […]
CELLS OF MYELOID LINEAGE
In the last article ‘Hematopoiesis’, we heard the term myeloid lineage/progenitor. These Cells (cells of myeloid lineage) are the first responder to infections. These cells include: Neutrophil, Basophil, Dendritic Cell, Monocytes and these are the parts of innate immunity. Granulocytes Granulocytes are known as PMN(polymorphonuclear leukocytes). Basophil, Neutrophil, and Eosinophils are categorized under granulocytes. These […]
Hematopoiesis
In adaptive and innate immunity, we have discussed the different types of cells such as lymphocytes, neutrophils, basophils. The process of the formation of these cells is known as hematopoiesis. Hemato = blood, poiesis =synthesis Hematopoiesis is the process to produce all the cellular components of blood. Hematopoiesis occurs during embryonic development and during adulthood […]
Lymphoid organs| Primary and secondary lymphoid organs
In previous articles, we have already discussed innate and adaptive immunity. If you have not read those articles, click here to read 1. Innate immunity 2. Adaptive immunity As we know cells forms tissue, tissue forms organs, and organs form a system. In this article, we have divided the cells and organs of the immune […]
ADAPTIVE IMMUNITY
Do you ever notice every time you exposed to a disease such as cold or the flu, the infection period for that disease gets shorter for the next time you are exposed to the same disease? Our adaptive immune system saves us from different infections by remembering the pathogen. It creates the memory of the […]
INNATE IMMUNITY
In our daily life, we are exposed to millions or trillions of pathogens, through contact, inhalation, or ingestion. We got an ability to avoid infection and this is the function of our immune system. This ability to resist infections is known as immunity. Immunity is interconnected in two systems: 1. Innate immunity 2. Adaptive immunity […]
NCBI (National Center for Biotechnology Information)
NCBI stands for the National center for biotechnology information which is a composite database. We already have discussed the databases (Read here). The URL for NCBI is https://ncbi.nlm.nih.gov NCBI is an important database for biotechnology students and researchers. There are various tools available for the analysis of data. NCBI is inside connected with other databases […]
Importance of Bioinformatics
Bioinformatics is the branch of science in which we use computer tools and algorithms to analyze biological data. Bioinformatics has its importance in the management and collection of biological data. Bioinformatics is an integrated interdisciplinary field it includes various subjects such as math, chemistry, genomics, proteomics, etc. Bioinformatics includes research applications in genomics data and […]
Antibodies and Antigen
In this article, we are going to learn about the basic introduction of antibodies and antigen. We’ll read in detail about their types and other functions in the next articles. what are antibodies? Antibodies are proteins that are produced by our immune system against foreign substances (such as bacteria or viruses) known as an antigen. […]
