The below mentioned article provides an overview on Cells and Organisms Used in Molecular Biology. For any molecular biological work or genetic engineering, the synthesis and cloning of any recombinant DNA involves introduction of this DNA into bacteria. Structure of E. coli: Among bacteria, escherichia coli are suitable for this purpose for the following reasons: i. It can be grown [...]
Let us make an in-depth study of informational macromolecules. Macromolecule of the cell can, conveniently be defined as, polymers of high molecular weight, assembled from relatively simple precursors. Many of the molecules found within cells, like the polysaccharides, proteins and nucleic acids are macromolecules. Macromolecules have molecular weights from tens of thousands to billions. Proteins have molecular weights ranging from [...]
This article throws light upon the five techniques used in conventional breeding programme. The five techniques are: (1) Embryo Culture (2) Ovary and Ovule Culture (3) Nucellus Culture (4) Control of Fertilization and (5) Endosperm Culture. Technique # i. Embryo Culture: Inter-specific crosses may fail because of several reasons, but when the development of embryo is arrested owing to the [...]
