A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.
Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.
This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

DNA is an example of a complex biological polymer called a nuclei acid. Nucleic acids are made up of many smaller sub units called nucleotides. The components of a DNA nucleotide are deoxyribose, phosphate group, nitrogen group. There are four possible bases in a DNA molecules which includes adenine, cytosine, guanine and tymine.
This is false, as macronutrients are all made of organic components. Macronutrients are carbohydrates, fats, and proteins. The most basic unit for carbohydrates is glucose. Glucose is an organic molecule with a chemical formula of C6H12O6 which then is broken down by the body to convert it to energy (in the form of ATP). Fats or triglycerides are comprised of fatty acids and a glycerol backbone which can also be used by the body for energy or can be stored for later use. Proteins on the other hand are functional molecules wherein the basic unit for proteins is the amino acid. Proteins are exemplified because they contain nitrogen (CHON). All of which can be used as energy and has specific caloric value per gram (4 kcal for every gram of protein and carbohydrates and 9 kcal for every gram of fat).
Micronutrients are usually inorganic compounds with no caloric value. Usually these micronutrients are essential for maintaining biochemical pathways in the body. For instance, niacin and riboflavin are vitamins that are needed in the production of NAD and FAD which are important for reduction-oxidation reactions in the body (i.e. tricarboxylic acid cycle and electron transport chain).
