1) DNA contains information on the primary structure of protein molecules.
2) This information is transferred to the i-RNA molecule, which transfers it from the nucleus to the ribosome, i.e. i-RNA serves as a matrix for the assembly of protein molecules.
3) T-RNAs attach amino acids and deliver them to the site of protein synthesis – to the ribosome.
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.
