Secondary Databases (PROSITE, PRINTS, BLOCKS)

Secondary Databases (PROSITE, PRINTS, BLOCKS  Secondary Databases Introduction Biological databases are broadly classified into primary and secondary databases. Primary databases store raw experimental data (e.g., nucleotide or protein sequences), whereas secondary databases contain derived information obtained by analyzing primary sequence data. Secondary databases are mainly used to: Identify protein families Detect conserved motifs, patterns, and domains Predict protein function Study structure–function relationships Examples of secondary databases include PROSITE, PRINTS, BLOCKS, Pfam, etc. 1. PROSITE Database Definition PROSITE is a secondary database that documents protein domains, families, and functional sites in the form of patterns and profiles. Developed by Swiss Institute of Bioinformatics (SIB) Maintained along with UniProt Principle PROSITE is based on the idea that functionally important regions of proteins are conserved during evolution. These conserved regions can ...

••CLASSIFICATION OF ALGAE - FRITSCH

      MODULE -1       PHYCOLOGY  CLASSIFICATION OF ALGAE - FRITSCH  ❖F.E. Fritsch (1935, 1945) in his book“The Structure and  Reproduction of the Algae”proposed a system of classification of  algae. He treated algae giving rank of division and divided it into 11  classes. His classification of algae is mainly based upon characters of  pigments, flagella and reserve food material.     Classification of Fritsch was based on the following criteria o Pigmentation. o Types of flagella  o Assimilatory products  o Thallus structure  o Method of reproduction          Fritsch divided algae into the following 11 classes  1. Chlorophyceae  2. Xanthophyceae  3. Chrysophyceae  4. Bacillariophyceae  5. Cryptophyceae  6. Dinophyceae  7. Chloromonadineae  8. Euglenineae    9. Phaeophyceae  10. Rhodophyceae  11. Myxophyce...

Intellectual Property Rights (IPR) – Detailed Notes

Intellectual Property Rights (IPR) – Detailed Notes 1. Introduction Intellectual Property Rights (IPR) are legal rights granted to creators and inventors over their creations or inventions. They protect innovation and creativity, providing the owner exclusive rights to use, sell, or license their creation. IPR encourages research, development, and economic growth by rewarding creativity. 2. Importance of IPR Protects inventions, designs, and creative work. Prevents unauthorized use, copying, or commercialization. Encourages innovation and research. Provides financial benefits to inventors through licensing or royalties. Supports economic growth and competitiveness. Safeguards traditional knowledge and biodiversity. 3. Types of Intellectual Property Rights A. Patents Definition: Exclusive right granted to an inventor for a new invention for a limited period (usually 20 years). Requirements: Novelty – must be new and not published.

❥ Southern Blotting Notes

Southern Blotting  ❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥ 𓆞❥  Introduction Southern blotting is a molecular biology technique used for the detection of specific DNA sequences in a complex mixture of DNA. It was developed by Edwin M. Southern in 1975. The method involves restriction digestion of DNA, separation by gel electrophoresis, transfer (blotting) onto a membrane, and hybridization with a labeled DNA probe. Principle of Southern Blotting The technique is based on the principle of complementary base pairing. A single-stranded labeled DNA probe hybridizes specifically with its complementary DNA sequence immobilized on a membrane. Detection of the label confirms the presence and size of the target DNA fragment. Steps Involved in Southern Blotting. 1. Isolation of DNA Genomic DNA is extracted from cells or tissues. DNA must be pure and intact to ensure accurate results. 2. Restriction Enzyme  Digestion DNA is digested using specific restriction endonucleases. Produces DNA f...

Electroporation – Detailed Notes

Electroporation – Detailed Notes Definition : Electroporation is a physical method of gene transfer in which cells are exposed to a brief, high-voltage electric pulse, creating temporary pores in the cell membrane. This allows DNA, RNA, proteins, or other molecules to enter the cytoplasm. It is widely used in bacteria, yeast, plant protoplasts, and mammalian cells. Key Concept: The electric field destabilizes the membrane, making it permeable to macromolecules. 1. Principle Cells are suspended in a conductive medium. A brief electrical pulse induces transient pores in the plasma membrane. DNA or other molecules present in the medium enter the cell through these pores. Membrane reseals after the pulse, and the molecule is retained inside the cell. Advantages of Principle: Direct and rapid. Works in many cell types. Does not require chemical carriers or viral vectors. 2. Materials Required Cells – bacterial, yeast, plant protoplasts, mammalian cells. DNA/RNA/other macromolecule – purifie...

❃LC-MS (LIQUID CHROMATOGRAPHY – MASS SPECTROMETRY)

LC-MS (LIQUID CHROMATOGRAPHY – MASS SPECTROMETRY)  ┏━━━━━ •❃°•°❀°•°❃•━━━━•━━━┓ 1. INTRODUCTION LC-MS is a hyphenated analytical technique combining Liquid Chromatography (LC) and Mass Spectrometry (MS). It is used for separation, identification, and quantification of compounds in complex mixtures. LC separates analytes based on polarity, size, or charge, while MS detects molecules based on mass-to-charge ratio (m/z). Developed in the 1970s–1980s, LC-MS is now widely used in pharmaceutical, clinical, environmental, and food analysis. Importance : Detects trace levels of compounds (ng–pg range) Analyzes non-volatile, thermally labile compounds that cannot be analyzed by GC-MS Provides structural information through mass fragmentation Example: Detection of drugs in plasma, protein identification in proteomics, pesticide residue analysis in food. 2. COMPONENTS OF LC-MS The LC-MS system has three main parts: A. Liquid Chromatograph (LC) Function: Separates components of a mixture befor...
