Question

Quizplus · Accepted Answer

The human-accelerated region 1 (HAR-1) gene is a small, noncoding RNA expressed specifically in the brain. It is thought to regulate gene expression in the developing human brain, although its exact function is not fully understood. The other answer choices are incorrect; for example, while HAR-1 was identified through genomic analysis, it is not a protein-coding gene and does not encode for protein products. Additionally, while HAR-1 is highly conserved between humans and chimpanzees, it is not identical between the two species.
