Answer

Salient Features of Human Genome:
  1. There are 3164.7 million nucleotide bases in the human genome.
  2. In an average gene, there are 3000 bases. The largest known human gene is Dystrophin (2.4 million bases).
  3. Total number of genes in human genome are estimated at 30,000. Almost, all (99.9%) of the nucleotide bases are exactly same in every human individual.
Applications and Future Challenges
  1. Its knowledge is helpful in research involving biological systems including human biology.
  2. With the whole genome sequences and newer technologies, we can be systematic in our approach to various medical questions on a broader scale.
  3. All the genes in a genome, e.g. all the transcripts in a particular tissue/ organ/ tumour can be studied.
