Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Answer:
Humans, like every other organism, are made up of cells. We all start off as just one cell at the time of fertilisation. As the single cell divides, all genes are copied so that every new cell possesses a full set of genetic material: the genome. The mechanism of copying the genome is quite remarkable considering that the human body contains approximately 10 trillion cells. The genome is made of a chemical called DNA or deoxyribonucleic acid and is organised in chromosomes, which contain genes.
