LIFE SCIENCE

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: -The Human Genome Project was a landmark global scientific effort whose signature goal was to generate the first sequence of the human genome.

Detailed explanation-3: -Two approaches have been used to sequence the genome. They differ in the method they use to cut up the DNA, assemble it in the correct order and whether they map chromosomes before decoding the sequence. First, there was the BAC to BAC approach. A second newer method is called whole genome shotgun sequencing.

Detailed explanation-4: -The international effort to sequence the 3 billion DNA letters in the human genome is considered by many to be one of the most ambitious scientific undertakings of all time, even compared to splitting the atom or going to the moon.

Detailed explanation-5: -Traditional genome-sequencing techniques chop the genome into small bits, spell out the exact order of the DNA base pairs in each chunk, then piece the whole thing back together using a standard human genome as a reference.
