Question

Quizplus · Accepted Answer

Most of a human's DNA is noncoding, meaning it does not directly code for proteins or functional RNA molecules. Instead, this noncoding DNA contains regulatory sequences and other elements that play important roles in gene expression, DNA replication, and genomic stability. This noncoding DNA is often referred to as "junk DNA," although it is becoming increasingly clear that much of it has important functions that are not yet fully understood. The human genome is double-stranded and eukaryotic, not prokaryotic.
