DNA Polymorphisms: Meaning and Classes | Genetics

In this article we will discuss about the meaning an classes of DNA polymorphisms. Meaning of DNA Polymorphisms: Different alleles of a gene produce different phenotypes which can be detected by making crosses between parents with different alleles of two or more genes. Then by determining recombinants in the progeny, a genetic map can be deduced. These are low resolution [...]

Palindromic DNA (With Diagram) | Biochemistry

The below mentioned article provides notes on palindromic DNA. In the DNA molecule a variety of base sequences have been observed. Most of them do not have special features. The repeated sequences are of particular interest because they are the site of enzymatic activity and, sometimes give special features to the nucleic acid. For the first time Wilson and Thomas [...]

Chargaff-Equivalence Rule for DNA | Biochemistry

In this article we will discuss about the Chargaff-equivalence rule for DNA. By 1948, a chemist Erwin Chargaff started using paper chromatography to analyse the base composition of DNA from a number of studies. In 1950, Chargaff discovered that in the DNA of different types of organisms the total amount of purines is equal to the total amount of pyrimidines [...]
