### Instruction: help me answer this question What are mRNA and rRNA? Define them., think step by step
### Assistant: Both mRNA and rRNA are essential for protein synthesis. mRNA carries the genetic information from DNA to the ribosomes, while rRNA plays a structural role in ribosomes and facilitates the protein synthesis process. , The answer is mRNA, or messenger RNA, is a type of RNA (ribonucleic acid) that plays a crucial role in biology. The primary function of mRNA is to carry genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.<br><br>rRNA, or ribosomal RNA, is another type of RNA that is a major component of ribosomes. Ribosomes are cellular structures where protein synthesis takes place. rRNA is vital for the assembly and function of ribosomes, helping to decode the mRNA and facilitating the formation of peptide bonds during protein synthesis.
