RNA contains ribose sugar instead of deoxyribose and uracil replaces thymine. Most RNA is single-stranded but tRNA forms a cloverleaf structure through complementary base pairing to carry amino acids to protein synthesis. DNA is found mainly in the nucleus while RNA exists in both the nucleus and cytoplasm, including messenger RNA which transports information from DNA to ribosomes, transfer RNA which carries amino acids, and ribosomal RNA which is a component of ribosomes for protein production.

2. RNA RNA has ribose sugar instead of deoxyribose sugar. The base uracil (U) replaces thymine (T) in RNA. Most RNAs are single stranded, although tRNA will form a "clover leaf" structure due to complementary base pairing. tRNA

4. Location DNA is restricted to the nucleus (in eukaryotes) with exceptions in chloroplasts and mitochondria. RNA occurs in the nucleus as well as in the cytoplasm

5. TYPES OF RNA mRNA (messenger RNA) Messenger RNA is RNA that carries information from DNA to the ribosome sites of protein synthesis in the cell. tRNA (transfer RNA) Transfer RNA is a small RNA chain of about 74 - 93 nucleotides that carries amino acids to the location of protein synthesis. rRNA (ribosomal RNA) Ribosomal RNA is a component of the Ribosomes, the protein synthetic factories in the cell.
