Dispute over number of human genes

Two rival teams that cracked the human genome may have underestimated the number of human genes, according to a new computer analysis.

“There are probably between 65,000 and 75,000 transcriptional units,” said Ohio State University’s Dr Yuan.

A transcriptional unit is a length of DNA that shows strong evidence of being a gene but which requires future verification.
