Question

Select the observations drawn from the human genome project which are correct.
(A) The human genome contains 3164.7 million bp.
(B) The average gene consists of 3000 bases.
(C) Total number of genes is estimated at 30,000.
(D) The functions are unknown for over 50% of discovered genes.
(E) Less than 2% of the genome codes for proteins.

• A. (A), (B), (C) and (D) only
• B. (A), (C), (D) and (E) only
• C. (A), (C) and (E) only
• D. (A), (B), (C), (D) and (E)

Answer 1

The Correct Option is D

The Human Genome Project yielded significant insights into our genetic composition. The following observations are evaluated for accuracy:

1. The human genome comprises 3164.7 million base pairs, a confirmed finding reflecting the genome's extensive size.
2. The average gene contains approximately 3000 bases, an estimate from the Human Genome Project illustrating the length of genetic sequences.
3. An estimated 30,000 genes were identified upon project completion, indicating the broad functionality encoded in our DNA.
4. The functions of over 50% of identified genes remain uncharacterized. This statement continues to be pertinent due to ongoing research and the discovery of new gene functions.
5. Protein-coding regions constitute less than 2% of the genome, underscoring the presence of substantial non-coding DNA involved in regulatory and structural processes.

Consequently, statements (A), (B), (C), (D), and (E) accurately represent findings from the Human Genome Project. The correct designation encompasses all these observations: (A), (B), (C), (D), and (E).
