yes RNA is made from DNA
there are three major types from RNA
1- rRNA "ribosomal RNA" is the RNA component of the ribosome, the protein manufacturing organelle of all living cells. Ribosomal RNA provides a mechanism for decoding mRNA into amino acids and interacts with tRNAs during translation by providing peptidyl transferase activity. The tRNAs bring the necessary amino acids corresponding to the appropriate mRNA codon.
2-Messenger RNA (mRNA) is a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes. Here, the nucleic acid polymer is translated into a polymer of amino acids: a protein. In mRNA as in DNA, genetic information is encoded in the sequence of nucleotides arranged into codons consisting of three bases each. Each codon encodes for a specific amino acid, except the stop codons that terminate protein synthesis.
3-Transfer RNA (tRNA) is a small RNA molecule (usually about 73-95 nucleotides that transfers a specific active amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation.
