Which is not the salient feature of human genome project-

The correct answer is Option (2) → Repeated sequences make up very small portion of the human genome.

Option (1) Less than 2 per cent of the genome codes for proteins. — A salient feature of the Human Genome Project. Only a very small part of our DNA is made of protein-coding genes. Most of it does not code for any protein.

Option (2) Repeated sequences make up very small portion of the human genome. — Not a salient feature of the Human Genome Project. The project found that repeated sequences make up a very large portion of the genome. NTA changed ‘large’ to ‘small’, and one word turned a feature of the genome into a false line. Read each option to its last word.

Option (3) The functions are unknown for over 50 per cent of the discovered genes. — A salient feature of the Human Genome Project. The sequence of a gene was found, but what more than half of the genes do is still not known.

Option (4) The average gene consists of 3000 bases, but sizes vary greatly, with the largest known human gene being dystrophin at 2.4 million bases. — A salient feature of the Human Genome Project. Genes differ greatly in size. Dystrophin, at 2.4 million bases, is the largest known human gene.
