Why are nucleic acids considered organic compounds? Complete Enzyme Handout!!! –

4 th group of macros… -CONTAINS HEREDITARY INFORMATION -THE BLUEPRINTS OF LIFE. - made of smaller repeating units of nucleotides

COMPOSED OF THREE PARTS PARTS: -SUGARS -PHOSPHATE GROUPS -NITROGENOUS GROUPS NUCLEOTIDE

LACK OF OXYGEN

DIVIDED INTO TWO CATEGORIES: &

TWO TYPES WHICH EXIST IN DNA & RNA ADENINE (A) AND GUANINE (G)

THERE ARE 3 TYPES. a. CYTOSINE (C) IS IN BOTH, RNA AND DNA b. THYMINE (T) IS IN DNA c. URACIL (U) IS IN RNA

IN 1953, WATSON AND CRICK (with help from Rosalind Franklin) DEDUCED THE SHAPE OF THE DNA AS AN ALPHA HELIX, WHERE THE DNA IS DESIGNED LIKE A LADDER.

SUGARS AND PHOSPHATES ALTERNATE GOING UP THE LADDER, ON THE OUTSIDE WHILE THE NITROGENOUS BASES HOLD THE MIDDLE, THROUGH WEAK HYDROGEN BONDS. **DNA is the nucleic acid which holds the codes for amino acid sequences of proteins.

IN A DNA STRAND, THE BASES PAIR UP AS FOLLOWS: C TO G A TO T IN A RNA STRAND, A BONDS w/ U

DEOXY- RIBOSE PHOSPHATE NITROGENOUS BASE BOND

ATP Nucleotide with 3 phosphate groups ATP is a storehouse of chemical energy Releases energy when bond is broken
