DNA and RNA

DNA  Contains deoxyribose sugar unit  Double stranded  Nitrogenous bases are: adenine, guanine, cytosine and thymine  Complementary base pairings:  A-T and G-C  Resides in the nucleus RNA  Contains ribose sugar unit  Single stranded  Nitrogenous bases are: adenine, guanine, cytosine and uracil  Complementary base pairings:  A-U and G-C  Resides in the nucleus and cytoplasm

 acts as the messenger between the DNA and the ribosome  translated into a protein by ribosomes  the sequence of nucleotides is derived from the DNA sequence in the gene

 is the delivery system of amino acids to the ribosomes as they synthesize the proteins  very short

Ribosomal RNA (rRNA)  binds with proteins to form ribosomes (structural component of the ribosome)  varies in length
