Question

What percentage of the human genome is coding?

Answer 1

Coding region of the human genome:

1. Following the Human Genome Project, scientists discovered that the genome had roughly 20,000 genes, a quantity that some researchers had projected.
2. Surprisingly, these genes make up only 1-2 % of human DNA's 3 billion base pairs.
3. This means that somewhere between 98 and 99 percent of our genome must be employed for something other than protein-coding, or non-coding DNA, as scientists call it.
4. Only about 1% of DNA is made up of protein-coding genes; the rest 95% is noncoding.
5. Protein-making instructions are not found in noncoding DNA.
