DNA is a double helix. The backone of DNA is made up of sugar and phosphate. There are four bases, or nucleotides, that make up it's nucleic acids, which are C, T, A, G (cytosine, thymine, adenine, guanine.). Even though there are four bases in a group, DNA only uses three at a time, to determine the group of nucleic acids. The number of nucleic acids that are included in one strand of DNA are 229.

DNA is the genetic blue print for living beings. DNA, also know as deoxyribonucleic acid, is the moleule of inheritane that determines your hereditary makeup. It had two nucleotide strands that are twisted together helically, and are also held together by hydrogen bonds. In the future DNA may be used to conduct small amounts of electricity, which is why when you get electricuted energy runs all throughout your body.

Chlorophyll is the green pigment in plants. It's formula is: CuH₇₃MgN₄O₅. The moleculare weight of chlorophyll is 893.48g. Chlorophyll has no density, melitng point or boiling point.

The organic structure of chlorophyll is made up of two ether groups and an aldehyde group. The structure has a nonpolar tail and a net-like ring that absorbs light. The magnesium is held in by nitrogen atoms which are useful for photosynthesis.

Chlorophyll's central ion is magnesuim and it's large organic molecule is porphryin. Porhyrin contains four nitrogen atoms that bond the magnesium atom in a square planar arrangment. Chlorophyll is used to channel the energy of sunlight into chemical energy. This process is also known as photosynthesis. In photosynthesis, electrons that come from water are transfered to carbon dioxide. Chlorophyll helps with this transfer. When the chlorophyll absorbs light, one of it's electrons becomes excited from a lower energy state and it moves to a higher energy state. The electron is transfered to another molecule in this higher energy state. This starts a series of steps that eventually leads to carbon dioxide. The chlprophyll that gave of the electron can now except another electron and the electron is removed from water.

ICl2^- is known as iodine dichloride,it's formula is ICl2. It has a molecular weight of 263.11 grams, but does not have a melting point, boiling point, or density because it is ionic. Iodine dichloride has a molecular shape that is linear, and a bond that is polar. Iodine dichloride has nine pairs of unshared electrons and two pairs of shared electrons, which makes this shape linear and not bent like water.
