Information Storage and Energy Transfer

Nucleic Acid BasicsMade of C,H,O,N,P SPONCHMonomer is a nucleotideFunctions

- information storage - information transfer

- energy transfer

Meet the Monomer-Nucleotide

P = Phosphate GroupS= 5 Carbon Sugar (ribose or deoxyribose)B= Nitrogen Base

Meet the PolymerPolymers of nucleic acids are chains of

nucleotides joined by condensation reactionsThey are held together by covalent bonds

between the sugar of one nucleotide and the phosphate of another

- called phosphodiester bonds

Meet the PolymersDNA 2 chains of nucleotides held RNA together by H Bonds

Nucleic Acid Types-DNA Deoxyribonucleic

Acidmade of two strands of

nucleotidesForm a double helixDNA stores hereditary

information - recipes for the

proteinsfound in the cell’s

nucleus

Nucleic Acid Types- RNA Ribonucleic Acid Single strand of

nucleotides forms a single helix transfers information

from the DNA to the ribosomes

- carries a protein recipe to the ribosome

-ribosomes are structures in a cell that make protein

DNA- stores protein recipes in the nucleusRNA – transfers them to the ribosome to be built

DNA vs. RNADouble stranded Single
