Genetic sequences
All the new cells produced by cell division contain DNA.
DNA contains a sequence of chemicals. The sequence is unique in every individual’s DNA.
Some DNA sequences are coded instructions for making Organic compound made up of amino acid molecules. One of the three main food groups, proteins are needed by the body for cell growth and repair. such as enzymes, hormones, muscle, hair and nails.
A DNA sequence that instructs a cell to make a protein is called a The basic unit of genetic material inherited from our parents. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production..
In animal, fungal and plant cells, DNA is stored in the nucleus. It is packaged up into chromosomes because there is so much of it. Proteins are made in the cytoplasm of the cell.
