- A Composed mainly of protein-coding exons with relatively few introns present
- B Made up of roughly 98% inert, largely non-functional junk DNA sequences
- C Largely transcribed with most non-coding regions having biochemical function
- D Composed mainly of transposons that serve little discernible biochemical function
Correct answer: C. Largely transcribed with most non-coding regions having biochemical function
Explanation: ENCODE: found ~80% of genome has biochemical activity (transcription, protein binding, chromatin modification). Most non-coding DNA has regulatory or structural roles.
