What processes occur in the cell nucleus in interphase?

1) In the G1-period (presynthetic period) RNA synthesis takes place: mRNA – transcription, rRNA, tRNA – necessary for protein biosynthesis), preparation for doubling DNA molecules is in progress.
2) In the S-period – there is a doubling of DNA (or DNA replication)
3) In the G2-period (postsynthetic period), the binding of DNA strands to proteins by histones begins, DNA spiralization begins (which ends in prophase)

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.
