Metabolically active cell growth phase is called pause-1 phase. This state is called antiphase. A cell that will no longer divide remains locked in the G1 subphase for a week or a year or forever. The characteristics of Birama-1 dasha are-
(i) Cell cycle starts in this state.
(ii) Whether a cell will participate in division depends on this stage.
(iii) Cyclin proteins, gabular proteins, fibrous proteins and RNA are produced in this subphase.
(iv) Cyclin protein binds to CDK and accelerates and regulates the process. CDK regulates the phosphorylation process.
(v) Enzymes are produced to make DNA and proteins.
(vi) Cytoplasm and nucleus of the cell increases in size.
(vii) Synthesis of various nucleotides and amino acids takes place.
(viii) In this state, the cells double in number.
(ix) Sub-phase takes 30-40% time.
