Embryo culture is also known as embryogenesis/ embryo rescue. Growth of a species during its embryonic stage in artificial culture medium (in-vitro) with aseptic conditions. First in 18th century by Charles bonnet in Phaseolus and Fagopyrum First successful embryo culture inside laboratory performed in 1904, by Hanning The fusion of anther(pollen) and ovary (ovule). Formation […]
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.
GLYCOLYSIS | Role of NAD and NADP
Glycolysis is a process of conversion of glucose into pyruvate by a series of intermediate metabolites. Glycolysis is a part of cellular respiration Each chemical modification is performed by a different enzyme. In this process, ATP is formed in the cytoplasm. ATP = energy. Steps of the process Step 1: Phosphate is transferred from ATP […]
DNA Structure and Function
DNA is deoxyribonucleic acid. DNA contains hereditary information in almost every organism. Almost every cell in our body has similar DNA structure. Most of the DNA present in our body located in the nucleus. Information in the DNA stored as codes that are chemical bases. Adenine (A), Guanine(G), Cytosine(c) and thymine(T) Adenine and Guanine are […]
Prokaryotic Vs. Eukaryotic cell
Every living organism except viruses has a Cellular organization. Organisms having only a single cell are known as unicellular organisms example bacteria, protozoa. Organisms having multiple cells in their body are known as multicellular organisms. Cells are of two types: Prokaryotic cells Eukaryotic cells The term prokaryote and eukaryote suggested in the 1960s by […]
Introduction to Plant Biotechnology
Plant biotechnology is a field of biological science, in which we study the use of tissue culture and genetic engineering and the techniques used for tissue culture and engineering.
Cellular Respiration
Cellular respiration is a complex metabolic pathway in which the glucose is broke down and get converted into an energy molecule (ATP).
Biological databases
WHAT ARE DATABASES? Databases are electronic cabinets used in storing retrieving and data management. A biological database is a large organized body of persisted data coming from various laboratories. E.g. NCBI, Swissprot Types of databases Primary database: These databases are also known as archival databases. Generally, these databases are populated with experimental data such as […]
CORONA VIRUSES
Coronaviruses are the RNA viruses that cause Respiratory tract infection in humans (range, mild to lethal infections). These viruses belongs to ….
History of Cell Biology
Cell biology A cell is the smallest unit of life. Cell biology is a field of biological science in which we study the structural and functional properties of a cell. History of cell biology: In 322-384 B.C. Aristotle and Paracelsus concluded that “all animals and plants, however, complicated, are constituted of a few-element which are […]
