Final answer:
mRNA is the type of RNA that is translated into proteins, carrying the genetic information from DNA to the ribosomes where proteins are synthesize(option c).
Step-by-step explanation:
The type of RNA that is converted into protein for performing its cellular function is option c: messenger RNA (mRNA).
mRNA is synthesized in the nucleus and carries the genetic message from DNA to the ribosomes in the cytoplasm, where it is translated into proteins. The other types of RNA, such as transfer RNA (tRNA), ribosomal RNA (rRNA), and microRNA (miRNA), have different roles. tRNA is responsible for transferring specific amino acids to the growing protein chain during synthesis, rRNA is a component of ribosomes which facilitates protein synthesis, and miRNA regulates the expression of genes by interacting with mRNA strands.
