Euploidy: Meaning and Classification | Genetics

In this article we will discuss about the meaning and classification of euploidy. Meaning of Euploidy: Most diploid sexually reproducing organisms have an alternation between a haploid and a diploid state in the life cycle. The haploid state, mostly confined to germ cells, is characterised by the presence of a single set of chromosomes (n). When two haploid germ cells [...]

Biology Notes on DNA Methylation | Genetics

The below mentioned article provides notes on DNA methylation. The DNA of many higher eukaryotes is modified after replication by methylation of cytosine bases at the 5-carbon position. The cytosines are incorporated in their normal unmodified form in the course of DNA replication; the methyl group (CH3) is then added by an enzyme DNA methylase. In mammals DNA is methylated [...]

Details of Structural Genes | Genetics

In this article we will discuss about the details of structural genes. Structural Genes: They control amino acid sequence of a protein by producing mRNA. There are as many structural genes as there are proteins which are regulated. Either a single mRNA is transcribed from each structural gene or, all the structural genes of an operon form a single polycistronic [...]
