1.	what is helix of dna and rna made up of????
Answer» DNA\xa0is\xa0made\xa0up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines\xa0DNA\'s\xa0instructions, or genetic code.\xa0Deoxyribonucleic\xa0acid\xa0(DNA) and ribonucleic\xa0acid\xa0(RNA) are polymers composed of monomers called nucleotides. An\xa0RNA\xa0nucleotide consists of a five-carbon sugar phosphate linked to one of four\xa0nucleic acid\xa0bases: guanine (G), cytosine (C), adenine (A) and uracil (U).\xa0Both\xa0DNA and RNA\xa0are\xa0made\xa0from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.\xa0DNA\xa0provides the code for the cell \'s activities, while\xa0RNA\xa0converts that code into proteins to carry\xa0out\xa0cellular functions.
