In a deed restricted community, a homeownersâ association (HOA) enforces rules pertaining to how your property is used and what it looks like. Most deed restricted communities require an HOA fee that pays for the communityâs upkeep and maintenance.
DNA, chromosomes and genes. Every cell in your body contains DNA (deoxyribonucleic acid). DNA, the genetic code for your body, exists as two long, paired strands spiraled into a double helix called a chromosome. DNA is like a blueprint that tells your body how to grow and develop. Each cell contains two copies of each chromosome, one copy inherited from your mother through the egg and one from your father through the sperm.
DNA and Genes. Genes are the blueprints of life. Genes control everything from hair color to blood sugar by telling cells which proteins to make, how much, when, and where. Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene.
