Detailed explanation-1: -The Human Genome Project is an international research project whose primary mission is to decipher the chemical sequence of the complete human genetic material (i.e., the entire genome), identify all 50, 000 to 100, 000 genes contained within the genome, and provide research tools to analyze all this genetic information.
Detailed explanation-2: -One goal of the project was to accurately sequence the 3 billion nucleotide base pairs in the human genome. A second goal was to map and identify all of the human genes present in the DNA sequence. (The number of genes is currently estimated to be between 20, 000 and 25, 000.)
Detailed explanation-3: -Goals of the human genome project include: Optimization of the data analysis. Sequencing the entire genome. Identification of the complete human genome.
Detailed explanation-4: -The human genome has approximately 3.1 billion base pairs. The Human Genome Project was started in 1990 with the goal of sequencing and identifying all base pairs in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. It is considered a megaproject.
