Nucleic Acids and ATP
ENDERGONICNucleic Acids and ATPNucleic AcidsElements: C, H, O, N, P, STwo types of Nucleic acids:DNA (Deoxyribonucleic Acid)RNA (Ribonucleic acid)DNA is Formed of in a "Double Helix" - like a spiral staircase.
NucleotidesDNA is formed from NucleotidesThese are made of 3 componentsA 5-Carbon SugarA Nitrogenous baseA Phosphate groupDNA/RNA backbone through linkages from the OH group of the 3rd carbon to a phosphate group of the adjoining nucleotide. These are called Phosphodiester bonds
Types of NucleotidesFor DNA There are 4 different Nucleotides categorized as either Purines (double ring) or Pyramidines (single ringed). These are usually represented by a letter.
These Are:Adenine (A)Cytosine (C)Guanine (G)Thymine (T)
Base Pairing RulesEach "Rung" of the DNA "staircase" is formed by the linking of 2 Nucleotides through Hydrogen Bonds.These Hydrogen bonds form only between specific Nucleotides. This is known as Base Pairing. The rules are as follows:Adenine (A) will ONLY bond to Thymine (T)Cytosine (C) will ONLY bond to Guanine (G)
RNAAKA ribonucleic acidRNA differs from DNA in several important ways.It is much smallerIt is single-strandedIt does NOT contain Thymine, but rather a new nucleotide called Uracil which will bind to Adenine.
ATP Short for Adenosine Tri-Phosphate. Composed of Ribose, Adenine & a phosphate groupPhosphate group has ability to bind/release additional phosphate group allowing it to store or release energyATP vs. ADP vs. AMP
