The modified plasmid then transports the DNA into a new cell. A large molecule composed of a linear sequence of amino acids. This linear sequence is a protein's primary structure. Further folding from interaction between sites in the secondary structure forms the tertiary structure of the protein. Proteins are essential to the structure and function of cells.
Restriction enzyme is a shorthand way of saying restriction endonuclease.
Therefore it is an enzyme that cuts the DNA molecule at specific locations along its length. Each type of restriction enzyme recognises a particular base sequence of the DNA and cuts precisely at the same point each time. In cells, RNA decodes the genetic instructions for synthesising proteins. In some viruses RNA is the genetic material. Living things of the same kind that are potentially capable of breeding and producing fertile offspring.
