What are nucleic acids? Nucleic acids are the carriers of genetic information In all living organisms the hereditary information is stored in deoxyribonucleic acid (DNA) which is a molecule formed by the repetition of nucleotides (making DNA a polymer) There are four different nucleotides in DNA which form a universal code
Nucleic acids are the molecules within a cell that are responsible for these amazing capabilities The first isolation of nucleic acid we now refer to as DNA was accomplished by Swiss physiologist Johann Friedrich Miescher circa 1870 while studying the nuclei of white blood cells
- nucleic acids are the carrier of genetic information and have a structure that is suited to that function - there are two main types of nucleic acids: DNA and RNA characteristic DNA RNA sugar deoxyribose ribose Number of strands Double-stranded Single-stranded base ATCG AUCG
Nucleic acids (DNA and RNA) perform a variety of crucial functions in organisms DNA stores and transfers genetic information it serves as the template for the synthesis of new DNA and RNAs while RNAs carry out protein synthesis Nucleic acids contain only a few different components but they have great structural diversity

What are the two classes of nucleic acids?
Nucleic Acids • Two classes • DNA (Deoxyribonucleic Acid) • RNA (Ribonucleic Acid) • Polymers of nucleotides • DNA carries genetic informationin the form of nucleotide sequence • Central Dogma of Biochemistry • DNA ? RNA ?Protein (Figure 11.1) Slide 3 Nucleotides • Composition • Heterocyclic Base • Pentose • Phosphate
Why are nucleic acids important?
Nucleic acids are the molecules within a cell that are responsible for these amazing capabilities. The first isolation of nucleic acid we now refer to as DNA was accomplished by Swiss physiologist Johann Friedrich Miescher circa 1870 while studying the nuclei of white blood cells.
What do nucleic acids and proteins have in common?
Nucleic acids and proteins share a characteristic, directionality, which affects how other molecules interact with them. Directionality exists when each end of the molecule is different from the other.
Is nucleic acid a polymer?
nucleic acid is a polymer in which the monomer units are nucleotides. There are two Types of Nucleic Acids: RNA: Ribonucleic Acid: Occurs in all parts of cell serving the primary function is to synthesize the proteins needed for cell functions. The nucleic acids are very large molecules that have two main parts.
