Iodine is an element. It there therefore cannot be broken down. Take a look at a periodic chart. It is element 53. Iodine is an essential trace element; its only known roles in biology are as constituents of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3). These are made from addition condensation products of the amino acid tyrosine, and are stored prior to release in a protein-like molecule called thryroglobulin. T4 and T3 contain four and three atoms of iodine per molecule, respectively. The thyroid gland actively absorbs iodide ion from the blood to make and release these hormones into the blood, actions which are regulated by a second hormone TSH from the pituitary. Thyroid hormones are phylogenetically very old molecules which are sythesized by most multicellular organisms, and which even have some effect on unicellular organisms.
Thyroid hormones play a very basic role in biology, acting on gene transcription to regulate the basal metabolic rate. The total deficiency of thyroid hormones can reduce basal metabolic rate up to 50%, while in excessive production of thyroid hormones the basal metabolic rate can be increased by 100%. T4 acts largely as a precursor to T3, which is (with some minor exceptions) the biologically active hormone

Iodine IS made of something - it is made of subatomic particles such as electrons, neutrons and protons. These in turn are made from even smaller particles such as quarks.
But since it is an element, no other elements can be chemically combined to make it. It could be possible to use a nuclear process such as fusion to produce Iodine.

Iodine is a solid which sublimes (vaporises) in air and therefore readily can become gaseous.
Solid iodine readily dissolves in a solution of potassium iodide.
Potassium iodide solution in itself is colourless, but becomes yellow or brown depending on how much iodine is dissolved.
Personally, I do not think that tincture of iodine contains alcohol but you would require to check that one out.

Iodine is an element and so isn't made of anything. Tincture of iodine is a solution of iodine in alcohol. Maybe that's what you mean?

Iodine is available commercially so it is not normally necessary to make it in the laboratory. Iodine occurs in seawater but in much smaller quantities than chloride or bromide. As for bromine, with suitable sources of brine, it is recovered commercially through the treatment of brine with chlorine gas and flushing through with air. In this treatment, iodide is oxidized to iodine by the chlorine gas.
2I- + Cl2 → 2Cl- + I2
Small amounts of iodine can be made through the reaction of solid sodium iodide, NaI, with concentrated sulphuric acid, H2SO4. The first stage is formation of HI, which is a gas, but under the reaction conditions some of the HI is oxidized by further H2SO4 to form iodine and sulphur dioxide.
