<p>My friend told me of a question from like Nov. 09 or something where it showed a picture of DNA and it asked "how many genes are present?"</p>
<p>What is the answer to this? How do you find out?</p>
<p>You can’t determine the number of genes from a diagram of a DNA segment. You can determine the number of codons.</p>
<p>Apparently you can… I might be missing some parts of the question but they don’t give you anything specific, just a picture.</p>
<p>Double-check the question with your friend. If we could do that, we could have saved billions of dollars spent on the Human Genome Project.</p>
