Final answer:
Hydrogen bonds connect cytosine (C) to guanine (G) in an RNA molecule, with each pair forming three hydrogen bonds, playing a critical role in RNA structure and function.
Step-by-step explanation:
The type of bonds that connect cytosine (C) to guanine (G) in a strand of RNA are hydrogen bonds. RNA is often single-stranded and has a backbone of ribose units connected by phosphodiester linkages. In RNA, guanine (G) forms three hydrogen bonds with cytosine (C), which is essential for the structure and function of RNA, including its role in protein synthesis where messenger RNA (mRNA) carries genetic instructions, and in the structure of ribosomes, which are mostly composed of RNA and are the site of protein synthesis.
