The possibility of sequencing an entire chromosome was first discussed in 1982 and the Human Genome Project dates back to 1986. Why this desire for ever longer genome sequences? There are following reasons for this urge: 1. Significance of Knowledge of the Complete Genetic Content of a Genome 2. Access to Important Genes 3. Identification of Genes for Human Diseases [...]
The following points highlight the three ways by which sequencing of genes in isolation from rest of human genome takes place. The ways are: 1. Complementary DNA (cDNA) Sequencing 2. Using CpG Island of Locate Genes 3. DNA Sequencing for Wheat Genome. Way # 1. Complementary DNA (cDNA) Sequencing: cDNA is made by converting the mRNA content of cell is [...]
The following points highlight the three important techniques for genome sequencing. The techniques are: 1. Shotgun Approach for Small Bacterial Genome 2. Sequencing of Mapped Clones for S.Cerevisiae Genome 3. Mapping and Sequencing the Human Genome. Technique # 1. Shotgun Approach for Small Bacterial Genome: The first bacterial sequence to be published, for the 1830 kb genome of the bacterium [...]
