••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...

RFLP (Restriction Fragment Length Polymorphism)

RFLP (Restriction Fragment Length Polymorphism ) Introduction RFLP is one of the earliest DNA-based molecular marker techniques. It detects variation in DNA sequences between individuals, caused by mutations, insertions, deletions, or restriction enzyme recognition site changes. First developed in late 1970s–1980s. Used extensively in genetic mapping, DNA fingerprinting, and gene detection. It is co-dominant, locus-specific, and highly reproducible. Principle RFLP is based on the fact that DNA from different individuals may differ in the presence or absence of restriction enzyme recognition sites, leading to different fragment sizes after digestion. Key idea: DNA → Restriction enzyme digestion → Fragments → Gel separation → Detection using labeled probe → Polymorphism analysis Materials Required Genomic DNA from the organism Restriction enzymes (e.g., EcoRI, HindIII) Agarose or polyacrylamide gel Nylon or nitrocellulose membrane Radioactive or non-radioactive DNA probe Autoradiography ...

Protein Sequence DatabasesPIR, SWISS-PROT and TREMBEL

Protein Sequence Databases PIR, SWISS-PROT and TREMBEL 1. Introduction Protein sequence databases are biological databases that store information about amino acid sequences of proteins, along with their functional, structural, and biochemical characteristics. Since proteins are the functional molecules of the cell, protein databases are essential for understanding gene expression, metabolism, enzymatic activity, signaling pathways, and evolution. Protein sequence databases mainly contain data derived from translated nucleotide sequences and experimental protein studies. 2. Types of Protein Sequence Databases Protein sequence databases are broadly classified into: A. Primary Protein Databases Contain original protein sequence data Minimal or no manual annotation B. Secondary Protein Databases Derived from primary databases Provide curated functional and structural information C. Composite Protein Databases Combine protein data from multiple sources Reduce redundancy 3. Protein Informati...

༺☆ DOT BLOT (DOT BLOTTING)

DOT BLOT (DOT BLOTTING) *ੈ✩‧₊˚༺☆༻*ੈ✩‧₊˚*ੈ✩‧₊˚༺☆༻*ੈ✩‧₊˚ Introduction Dot blot is a simple and rapid molecular biology technique used to detect specific DNA, RNA, or proteins immobilized directly onto a solid membrane without electrophoretic separation. It is a modification of Southern, Northern, and Western blotting, but unlike them, dot blot does not involve gel electrophoresis. The technique is mainly used for screening large numbers of samples, qualitative or semi-quantitative analysis, and diagnostic purposes. Principle of Dot Blot The principle of dot blotting is based on specific binding between a target molecule and a labeled probe or antibody. The sample containing DNA/RNA/protein is directly applied as a dot on a nitrocellulose or nylon membrane. The molecules bind to the membrane by hydrophobic and electrostatic interactions. The membrane is then incubated with a specific probe (for nucleic acids) or antibody (for proteins). Detection is achieved using radioactive, enzymatic, ...

❃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...

Exploitation of Somaclonal and Gametoclonal Variations for Plant Improvement

Exploitation of Somaclonal and Gametoclonal Variations for Plant Improvement 1. Introduction Plant tissue culture often induces genetic and epigenetic variations among regenerated plants. These variations, when stable and heritable, can be exploited as a source of novel traits for crop improvement. Somaclonal variation: Variation arising in plants regenerated from somatic cells cultured in vitro. Gametoclonal variation: Variation arising in plants regenerated from gametic cells (anther, pollen, ovule culture). Both provide additional genetic variability beyond conventional breeding. 2. Somaclonal Variation 2.1 Definition Somaclonal variation refers to genetic variation observed among plants regenerated from somatic tissue cultures, such as callus, suspension cultures, or explants. Term coined by Larkin and Scowcroft (1981). 2.2 Sources of Somaclonal Variation Chromosomal changes Aneuploidy Polyploidy Chromosome rearrangements Gene mutations Point mutations Insertions and deletions...

❥ 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...

❃HPLC – High Performance Liquid Chromatography

HPLC – High Performance Liquid Chromatography ┏━━━━━ •❃°•°❀°•°❃•━━━━•━━━┓ 1. Introduction High Performance Liquid Chromatography (HPLC) is an advanced analytical technique used for the separation, identification, and quantification of components present in a mixture. It is based on the differential distribution of analytes between a stationary phase and a liquid mobile phase under high pressure. HPLC is widely used in biochemistry, biotechnology, pharmaceuticals, food analysis, environmental studies, and clinical diagnostics. 2. Principle of HPLC The principle of HPLC is based on partition, adsorption, ion-exchange, or size-exclusion mechanisms, depending on the type of column used. A liquid mobile phase is pumped at high pressure through a column packed with fine stationary phase particles Sample components interact differently with the stationary phase Components with stronger interaction elute slower Components with weaker interaction elute faster Separated components are detec...
