Human Genome

The human genome project has unveiled several significant findings about our genetic makeup. Let's analyze each provided observation to determine their validity:

1. The human genome contains 3164.7 million base pairs. This is a factual statement supported by the project's findings, confirming the vast size of our genome.
2. The average gene consists of 3000 bases. This is an approximate value given by the Human Genome Project, highlighting the complexity and length of genetic sequences.
3. The total number of genes is estimated at 30,000. This was a prominent estimation at the time of the project's completion, reflecting the extensive functionality encoded in our DNA.
4. The functions are unknown for over 50% of discovered genes. Given the continuous research progress and discovery of gene functions, this statement remains relevant as we still do not fully understand the role of many genes.
5. Less than 2% of the genome codes for proteins. This highlights the large non-coding regions within the genome, which play various regulatory and structural roles despite not directly coding for proteins.

Therefore, each statement (A), (B), (C), (D), and (E) accurately reflects findings from the Human Genome Project. Hence, the correct option is presented through the compilation of all observations (A), (B), (C), (D) and (E).
