What processes underlie the transmission of hereditary information from generation to generation
What processes underlie the transmission of hereditary information from generation to generation and from the nucleus to the cytoplasm, to the site of protein synthesis?
The basis of the transmission of hereditary information from generation to generation is meiosis. Transcription (from lat. Transcription – rewriting). Information on the structure of proteins is stored as DNA in the cell nucleus, and protein synthesis occurs on ribosomes in the cytoplasm. Informational RNA acts as an intermediary transmitting information about the structure of a particular protein molecule to the place of its synthesis. Broadcast (from lat. Trans lation – transmission). The mRNA molecules exit through the nuclear pores into the cytoplasm, where the second stage of realization of hereditary information begins – the translation of information from the “language” of RNA to the “language” of the protein.
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.
