alleryAccording to HGP findings, what percentage of the human genome codes for proteins?
ALess than 2%
B~50%
C~25%
D~98%
Answer & Solution
Correct answer: A. Less than 2%
Surprisingly, **less than 2% of the human genome codes for proteins**.
**The remainder is non-coding:** regulatory regions, introns, repetitive sequences, and untranscribed DNA.
SNPs (~1.4 million) drive person-to-person variation.
