Question

Which of these statements regarding the Human genome project are correct?
1. Human genome consists of approximately 30,000 genes
2. The average gene consists of 3000 bases
3. The functions are unknown for over 50% of discovered genes

• A. 1, 2
• B. 2, 3
• C. 1, 3
• D. 1, 2, 3

Answer 1

The correct option is D 1, 2, 3

The Human Genome Project (HGP) aims at finding out the sequence of the entire human genome. It was started in 1990 and scientists from various countries were involved. It was coordinated by the U.S. Department of Energy and the National Institute of Health. The project was completed in 2003.

This project gives a lot of information on the human genome.

Some salient features of the human genome are:

• The human genome consists of approximately 30,000 genes which is much lower than the earlier estimates of 80,000 to 1,40,000 genes.
• The size of the genes varies greatly but the average gene is said to contain 3000 bases.
• The function remains unknown for over 50% of discovered genes.
