Best Answer

RNA and DNA are collectively known as nucleic acids. DNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid DNA is the immutable code that is always stored inside the nucleus. It carries the directions with making all RNA and proteins inside a cell. When an RNA is made from DNA, the process is called transcription. Many types of RNA can be made from DNA, including mRNA, tRNA, rRNA, snRNA, snoRNA. Amongst these mRNA is responsible for carrying the directions for making proteins out of the nucleus to the endoplasmic reticulum where protein synthesis occurs. tRNA is responsible for carrying amino acids to ribosomes for protein synthesis. rRNA is a part of ribosomes and essential to the process of protein synthesis. snRNAs, snoRNAs, and several other types of RNAs haev more obscure functions and more information can be found in the links below.
