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 [...]

Structural Features of DNA | Genetics

In this article we will discuss about some of the important structural features of DNA. 1. DNA exists as a double helix in which the two polynucleotide chains are coiled about one another in a spiral with a diameter of about 20Å (Fig. 1). 2. Concentration of thymine was always equal to the concentration of adenine and the concentration of [...]

Replication of DNA | Genetics

In this article we will discuss about the mechanism for the replication of DNA. The mechanism for the synthesis of DNA proposed by Watson and Crick offered the important advantage of explaining how new DNA molecules could be exact replicates of the old. According to Watson and Crick, each single strand is a template on mold for its complement, and [...]
