    DNA and RNA?

    What is the relationship between DNA and RNA? And does DNA make RNA?

    Rna like a messenger that ask to made dna

    DNA stands for deoxyribonucleic acid
    RNA stands for ribonucleic acid

    DNA is used for animal genetic coding. They are made up of two strands of sugar and phosphate stings, with 'rungs' of adenine, thymine, guanine or cytosine. There for several nucleotides. Cytosine can only bond with Guanine, Tymine can only bond with adenine. The order of which these bonds are formed decided animal or plant genetics.

    Some organisms use RNA. This is a single strand of DNA. This is most commonly used by viruses. They inject this RNA into the host cell in order to change the role of the cell to make more of the virus instead of its normal function by replacing its genetic coding.

    Hope this helps!

    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.

    The main difference between DNA and RNA is the sugar present in the molecules. While the sugar present in a RNA molecule is ribose, the sugar present in a molecule of DNA is deoxyribose. Deoxyribose is the same as ribose, except that the former has one more OH.

    DNA does not usually exist as a single molecule, but instead as a tightly-associated pair of molecules. These two long strands entwine like vines, in the shape of a double helix. This arrangement of DNA strands is called antiparallel. The asymmetric ends of DNA strands are referred to as the 5? (five prime) and 3? (three prime) ends. One of the major differences between DNA and RNA is the sugar, with 2-deoxyribose being replaced by the alternative pentose sugar ribose in RNA. The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). A fifth pyrimidine base, called uracil (U), usually takes the place of thymine in RNA and differs from thymine by lacking a methyl group on its ring.

    DNA and RNA are the Ellemetary Organic Structures, quite correctly defined by my friend john jackson ...

    However, These are Primarily Paired Forms, ... The DNA being a distict Paired Form, made up of Two Paired Protein Structures, whereas the RNA is presently considered as a Single Pairs based Strand ...thus, a Viral or pernaceous Form. 

    The Truth [Moecular Biology does not as yet know] is, that an RNA is a Paired Form, with one of its Composing Pair, of Elementary Amino Acid Structures, having undergone  Structural Damage ...
