Detailed explanation-1: -human genome, all of the approximately three billion base pairs of deoxyribonucleic acid (DNA) that make up the entire set of chromosomes of the human organism.
Detailed explanation-2: -A genome is all of the genetic material in an organism. It is made of DNA (or RNA in some viruses) and includes genes and other elements that control the activity of those genes.
Detailed explanation-3: -Human genome project was aimed to determine the complete base sequence of human DNA. Human genome project is called a mega project because. (i) Its aim was to determine the nucleotide sequence of complete human genome which was a task of enormous magnitude.
Detailed explanation-4: -3.2 billion That’s how many base pairs-or sets of genetic “letters"-make up the human genome. In order to list all those letters, a person would have to type 60 words per minute, 8 hours a day, for about 50 years! However, humans are by no means the species with the most base pairs.
Detailed explanation-5: -All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases.
