Inserted into other dna molecules: three main types: Mitosis is the process of cells division that produces two genetically identical daughter cells form one original parental cell. It is precisely controlled to prevent either an excess or insufficient number of cells. G1; cells in g0 never progress through the cell cycle: eg. Brain cells: during s phase, dna replication results in doubling of the dna in each nucleus, two sister chromatids are produced for each chromosome, the completion of s phase leads into. Mitosis produces identical daughter cells: mitosis separates replicated copies of sister chromatids into identical nuclei, forming tow genetically identical daughter cells, the diploid number of chromosomes (2n) is maintained throughout the cell cycle. Transcription: information from dna is transferred to rna: mrna (messenger rna): encodes polypeptides trna (transfer rna): plays role in protein synthesis rrna (ribosomal arna): plays role in protein synthesis, 3.
