Question

As per latest information human genome has

• A. $3,00,000$ genes
• B. $20,000$ genes
• C. $3,000$ genes
• D. $300$ genes

Answer 1

Answer: (B)

$20,000$ genes

There are an estimated 19,000-20,000 human protein-coding genes. The estimate of the number of human genes has been repeatedly revised down from initial predictions of 100,000 or more as genome sequence quality and gene finding methods have improved and could continue to drop further.

So, the correct answer is '20,000 genes'.
