The first two that are involved in making sure the amino acids pair up properly are transfer RNA and messenger RNA (tRNA and mRNA). The tRNA picks up the right amino acid through the guidance of enzymes then it is transferred to mRNA. Ribosomal RNA (rRNA) is the third and is involved in bringing the amino acid process to a halt at the stop condons.
♦ Like DNA, RNA consists of a chain of chemical compounds called nucleotides.In cellular organisms, RNA is a single-stranded polynucleotide chain, a strand of many nucleotides linked together
♦There are three types of RNA.Ribosomal RNA (rRNA) is found in the cell's ribosomes, the specialized structures that are the sites of protein synthesis).Transfer RNA (tRNA) carries amino acids to the ribosomes for incorporation into a protein.Messenger RNA (mRNA) carries the genetic blueprint copied from the sequence of bases in a cell's DNA. This blueprint specifies the sequence of amino acids in a protein.All three types of RNA are formed as needed, using specific sections of the cell's DNA as templates.
