Cellular RNAs are formed during a process called transcription, that is, RNA synthesis on a DNA matrix carried out by special enzymes – RNA polymerases. Then, messenger RNAs (mRNAs) are spliced and take part in a process called translation. Translation is the synthesis of protein on the mRNA matrix with the participation of ribosomes. Other RNAs after transcription undergo chemical modifications, and after the formation of secondary and tertiary structures, they perform functions that depend on the type of RNA.
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.
