The human genome project discovered that protein coding regions make up what percent of the human genome?

• A. 1%
• B. 2%
• C. 10%
• D. 90%

Answer: (B)

Verified step by step guidance

1. Understand the context: The human genome consists of all the DNA in a human cell, including both coding and non-coding regions.
2. Recognize the significance of protein-coding regions: These are parts of the genome that are transcribed into mRNA and translated into proteins, which perform various functions in the body.
3. Recall findings from the Human Genome Project: This project mapped the entire human genome and provided insights into the proportion of coding versus non-coding DNA.
4. Consider the options given: Analyze each percentage option in the context of known scientific data about the human genome.
5. Conclude based on scientific consensus: The Human Genome Project revealed that protein-coding regions constitute a small fraction of the genome, much less than 10% or 90%.
