Transcript of Nucleic Acid Nucleic Acids Examples: – RNA (ribonucleic acid) single helix – DNA...
Nucleic Acid
Nucleic Acids• Examples:– RNA (ribonucleic acid)• single helix
– DNA (deoxyribonucleic acid)• double helix
• Structure:– monomers = nucleotides
RNADNA
proteinsproteins
DNADNA
Nucleic Acids• Function:– genetic material• stores information–genes–blueprint for building proteins»DNA RNA proteins
• transfers information–blueprint for new cells–blueprint for next generation

Genes (DNA)are needed to run bodies every day…to make you and me…to make new cells…to make babies!
Nucleic acids
•Building block =nucleotides
Nucleotides are made of 3 parts Phosphate group, sugar , and nitrogen base
5 different nucleotides different nitrogen bases A, T, C, G, U
nucleotide – nucleotide – nucleotide – nucleotide
phosphate
sugar N base
Nitrogen basesI’m the A,T,C,G or Upart!
Nucleotide chains• Nucleic acids nucleotides chained into a polymerDeoxyribonucleic acid (DNA Structure)
- Double (two) strands- Double helix - Nucleotides : Adenine (A)
Thymine (T)Guanine (G)Cytosine (C)A bonds with T G bonds with C
