Structure of DNA and RNA Flashcards
DNA Role
Holds genetic information
RNA Role
Transfers genetic information from DNA to the ribosomes
Ribosome components
RNA and proteins
Nucleotide components
Pentose, a nitrogen-containing organic base and a phosphate group
Components of a DNA nucleotide
Deoxyribose, a phosphate group and one of the organic bases adenine, cytosine, guanine or thymine
Components of an RNA nucleotide
Ribose, a phosphate group and one of the organic bases adenine, cytosine, guanine or uracil
A condensation reaction between two nucleotides forms a
Phosphodiester Bond
DNA molecule properties
Double helix with two polynucleotide chains held together by hydrogen bonds between specific complementary base pairs
RNA molecule properties
Relatively short polynucleotide chain
