cytoplsm karyoplasms or nucleoplasm
The 3 parts are :G1 Phase (growth 1st phase ):cell organelles increase their size.Biomolecule/hyloplasm/cytosole increase their concentration and phosphate group ,nitrogenous bases n sugar also increase their concentration.Size of nucleus increase.Chromosomes change into chromatin material.S-Phase (synthesis phase):dna replication ,transcription and translation take placeDNA -> DNA (replication)DNA ->RNA (transcription)RNA-> Protein (translation)if nuleotide is doubled then no. of gene also doubled and DNA also doubled but chromosomes just as it is because dna present on chromosome .G2 Phase(growth 2nd phse):No. of cell organelles increase.Centriole divide into 2 portions.ATP production increase because no. of mitochondria increase so ATP increase.
