what phase does mitochondria replicate
â Interphase (grey) is the longest phase which itself occurs in three stages. â G1 The cell performs its normal differentiated function. Protein synthesis/ mitochondria replication/ chloroplast replication. â S DNA replication. At this point the mass of DNA in the cell has doubled.
2.5.3 State that interphase is an active period in the life of a cell when many metabolic reactions occur, including protein synthesis, DNA replication and an increase in the number of mitochondria and/or chloroplasts. During interphase the cell grows larger.
