Storage and transmission of hereditary information. DNA contains information about the primary structure of all the proteins that the body needs. This information is recorded in a linear nucleotide sequence. Since proteins play a paramount role in the life of the body, participating in the structure, development, metabolism, it can be argued that DNA stores information about the body. In RNA, each of its types performs its function depending on its structure. m-RNA is a copy of a DNA site where information on the number, composition and sequence of amino acid residues that determine the structure and function of a protein molecule is recorded. This RNA contains a plan for building a polypeptide molecule. t-RNA – its role is to attach an amino acid molecule and transport it to the site of protein synthesis. r-RNA – binds to a protein and forms special organoids – ribosomes, on which protein molecules are assembled in the cell of any living organism.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
