Top 8 Methodologies Neces­sary for Genetic Research

The following points highlight the top eight methodologies necessary for genetic research. The methodologies are:- 1. Isolation of Plasmids 2. Isolation of Chromosomal DNA 3. Agarose Gel Electrophoresis 4. Restriction and Ligation 5. Transformation 6. Polyacrylamide Gel Electrophoresis 7. Two-Dimensional Electrophoresis and 8. Immunoelectrophoresis. Methodology # 1. Isolation of Plasmids: Plasmids are self-replicating, extrachro-mosomal genetic elements found in bacteria. They [...]

Physical Basis of Heredity with Theories | Genetics

In this article we will discuss about the physical basis of heredity with theories investigated by a great number of workers, some of whose results are as follows: Encasement Theory: One of the older, but now abandoned, ideas was set forth in the preformation or encasement theory, which supposed that the germs of all future genera­tion were encased one within [...]

Morphologic Characteristics of Chromosomes | Genetics

The morphologic characteristics of chromosomes are best studied during metaphase and anaphase of cell division. The chromosome was supposed to be covered by a membranous Pellicle. Electron microscope studies later showed that there is no definite membranous pellicle surrounding the chromosomes. A matrix of some sort, possibly protein, lipid, may be present. Other structures present in the chromosome include the [...]
