The following points highlight the top five techniques of chromosome banding. The techniques are: 1. C-Bands 2. G.Bands 3. Q-Bands 4. N-Bands 5. Other Techniques of Chromosome Banding. Chromosome Banding: Technique # 1. C-Bands: The technique of C-banding originated after the work of Pardue and Gall who reported that constitutive heterochromatin can be stained specifically by Giemsa-solution. Each chromosome possesses [...]
In this article we will discuss about the meaning and structure of nucleic acids. Meaning of Nucleic Acids: Nucleic acids are a long chain polymers of nucleotides which are joined together by means of phosphodiester linkages. In phosphodiester bonds, one phosphoric acid molecule forms bonds with the 3' carbon of one pentose molecule as well as with the 5' carbon [...]
In this article we will discuss about:- 1. Meaning of Chromosomes 2. Chromosome Number 3. General Morphology. Meaning of Chromosomes: In 1875, Strasburger discovered thread-like structures which appeared during cell division. Later, these structures were termed as chromosomes (chroma = colour; soma = body) by Waldeyer in 1888 since they showed affinity for basic dyes and could be stained deeply, [...]
