SIMILARITIES & DIFFERENCES BETWEEN DNA & RNA CHARACTERISTIC DNA RNA Name Deoxyribonucleic Acid Ribonucleic Acid Deoxyribose Ribose Name of sugar Nucleotide Structure Phosphodiester linkage Phosphodiester linkage Bond linking nucleotides together Adenine & Thymine (2 H bonds) No pairing (single stranded) Cytosine & Guanine (3 H bonds) Pairing of nucleotides * will complimentary base-pair to DNA during protein synthesis, uracil used in place of thymine Double stranded, helical structure Single stranded, helical structure Anti-parallel strands Have directionality (5’ → 3’) Overall description Have directionality (5’ → 3’) Strands held together by H-bonds One type, located in nucleus of the cell Many types of RNA, 3 used in protein (eukaryotes) synthesis (rRNA, tRNA, mRNA) # of types & location in Located in cytoplasm (prokaryotes) Located in nucleus and in the cytoplasm cell (eukaryotes) Located in cytoplasm (prokaryotes) The DNA molecule contains a nucleotide RNA molecules are used to copy and sequence that acts as a “blueprint” for transfer the “code” of the DNA blueprint making proteins in the body. out into the cytoplasm. Importance/Use Every protein is coded for by a single gene. They are used to “build” the polypeptide using amino acids, with the help of ribosomes.
