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 [...]
In this essay we will discuss about the outbreeding which is a negative genetic assortative mating. When a mating involves individuals that are more distantly related than the average of the selected group, it is classified as outcrossing or outbreeding which is a negative genetic assortative mating. Outbreeding involves crossing individuals belonging to different families or crossing different inbred varieties [...]
Geneticists use following two methods for sequencing the genomes: 1. Clone-by-clone Method 2. Shotgun Cloning. Method # 1. Clone-by-Clone Method: This method was the first to be developed. It begins with the construction of genomic libraries of restriction fragments covering all the genomic DNA (or genomic clones) of an organism. By using genetic markers, overlapping clones are assembled into genetic [...]
