In the entire genome, the exonic DNA constitutes: (A) 1.50%, (B) 0.50%, (C) 0.10%, (D) 0.02%
Answer is A. Human genome: Size: 3 billion base pairs Number of genes: <25,000 At least 30% of the genome consists of repetitive sequences Alu family constitutes ~10% of human genome Largest gene: DMD gene coding for dystrophin protein Only around 1.5 % of human genome is made of protein-coding (exonic) DNA
