Question

What is the estimated number of genes in the human genome?

विकल्प

• 5,000 to 10,000 genes

• 50,000 to 100,000 genes

• 100,000 to 200,000 genes

• 20,000 to 25,000 genes

Answer 1

The Human Genome Project estimated that the human genome contains approximately 20,000 to 25,000 genes. This number was significantly lower than previous predictions and represents a fundamental insight into human genetic organization, suggesting that genetic complexity arises not just from gene number but from alternative splicing and protein modifications.
