D)act independently and do not collaborate with another gene.

Question

Quizplus · Accepted Answer

Genes are responsible for manufacturing the proteins necessary for maintaining life. They consist of segments of DNA that are transcribed into RNA and then translated into proteins. Proteins are essential for a wide variety of cellular functions, including cell structure, metabolism, and signaling. Therefore, C is the best choice.

A is incorrect because genes consist of segments of DNA, not ribosomes composed of RNA. 
B is incorrect because genes do not match and link small pieces of RNA, although RNA molecules can sometimes interact with and regulate gene expression. 
D is incorrect because genes often act in concert with other genes to regulate cellular processes.
