Question

Quizplus · Accepted Answer

Orphan genes are genes with no known function or homology to other genes.

Answer: G 
 Riboswitches are RNA sequences that can control gene expression by binding to specific molecules, but the function of many of these genes is still unknown.

Answer: A, H 
 Hemoglobin genes (such as globin) are well-known functional genes, while histones are structural proteins that are necessary for DNA packaging, but some histone variants have unknown functions.

Answer: I
