Answer:
zRNA
Explanation:
RNA is a nucleic acid responsible for the synthesis of proteins, since it is the molecule that carries the information contained in DNA for the biological process called transcription.
There are three types of RNA, the mRNA, the tRNA and the rRNA. There is no RNA called a zRNA, however, existing RNAs have different functions. These functions are listed below:
The mRNA is called messenger RNA and is the RNA responsible for containing the DNA information that will be translated into proteins created during protein synthesis.
The tRNA is responsible for identifying the information presented by the mRNA, creating amino acids from it and transporting those amino acids in the right order to form proteins.
rRNA is also called ribosomal RNA and is responsible for creating ribosomes, which are the organelles where protein synthesis will take place.
