NUCLEIC ACIDS
A huge polymer composed of nucleotides
NUCLEOTIDES- are the building blocks
of nucleic acids.
NUCLEOTIDES
A single stranded nucleic acid molecule are held
together by covalent bonds.
DNA NUCLEOTIDES-Building blocks of DNA
RNA NUCLEOTIDES- Building blocks of RNA
2 major types of Nucleic Acids
DEOXYRIBONUCLEIC ACIDS(DNA)
• The hereditary molecule
• Present in the chromosomes of the nucleus
• Responsible for the transfer of genetic information
• Deoxy means without oxygen
RIBONUCLEIC ACID(RNA)
•Primarily concern with the synthesis of
protein
•Not found in the chromosomes but is located
elsewhere in the nucleus and even outside of
it: in the CYTOPLASM
PYRAMIDINE BASES
• CYTOSINE(C)- Found in both RNA and DNA
• THYMINE (T)- In DNA thymine is substituted
for Uracil.
• URACIL (U)- found only in RNA
PURIINE BASES
•ADENINE (A) AND GUANINE (G)-
Both found in DNA and RNA
DNA
•GUANINE (G)= CYTOSINE(C)
•CYTOSINE(C) = GUANINE(G)
•ADENINE (A) =THYMINE(T)
•THYMINE(T) = ADENINE (A)
RNA
•GUANINE (G)= CYTOSINE(C)
•CYTOSINE(C) = GUANINE(G)
•ADENINE (A) =URACIL (U)
•URACIL (U)= ADENINE (A)
