Cell division is an important part of reproduction, growth, and development.There are two types of cell divisions in organisms.The cell cycle consists of two phases.Interphase is the longest phase in which cells grow and make a copy of their genes.Interphase has three substages; G1 phase, S phase and G2 phase.The duration of the sub-phases depends on the type of organisms.The G1 phase has a longer process than the G2 phase and is considered to be a short phase.During the G1 phase, the cell shows first growth by copying and making the building blocks which are necessary for later steps.The second growth can be seen during the G2 phase when the cell begins to reorganize its contents.The key difference between the first and second phases of a cell cycle is this.
1.There is an overview and a key difference.What is the beginning of the cell cycle?What is the G2 phase of the cell cycle?There are similarities between the G1 and G2 phases of the cell cycle.There is a side by side comparison between the G1 and G2 phases of the cell cycle.Summary.
The interphase of the cell cycle begins with the G1 phase.This stage is called Gap 1 stage.The first stage of interphase is called G1 phase.There are significant development processes within the cell.The cell’s size will increase due to the extensive synthesis of genes.During the replication of DNA, it helps.Histone is one of the histone proteins that is synthesised during the G1 phase.Most of theRNA is made up of genes.Histone is involved in DNA replication.
Depending on the type of organisms, the duration of the cell cycles varies.Some organisms have a longer G1 phase before entering the S phase.The average cell cycle in humans is 18 hours.The G1 phase takes 1/3 of the total time for the complete cell cycle process.There are certain factors that may change this time.The factors that are referred to as growth factors are the cellular environment, availability of nutrients, and cellular temperature.The proper growth of organisms is affected by the temperature.The optimum temperature for cellular growth in humans is 37 0C.
The duration and coordination between other phases are regulated by the cell cycle regulatory mechanism.The G1 phase is considered to be an important phase since it determines the fate of a cell if it continues with the rest of the cell cycle or leaves it.The cell won’t enter into the S phase if a signal is kept at an un-dividing stage.The cell will move into a phase known as G0 phase without division.
Once the G1 phase and S phase are completed, the cell will enter into the second phase.It’s also called the Gap 2 phase.The final stage of interphase is called G2 phase.The G2 phase is shorter than the G1 phase.It is considered to be an important phase in the cell cycle since extensive cellular growth takes place under high synthesis rate of proteins.The formation of spindle apparatus is aided by the synthesis of necessary RNA and proteins.Even though this stage is important, it can be avoided by a cell and thus, can enter into the phase once S phase is completed.By completing the G2 phase, the cell becomes fully prepared for the disease.
If a cell enters the G2 phase, it means that the S phase has been completed.The cells in the G2 phase will be divided into two identical daughter cells.In G2 phase, the cell size increases along with different components such as the nucleus.The G2 phase is also regulated by cell cycle regulatory mechanisms.The interphase of the cell division is completed once the G2 phase is complete.
The interphase of the cell cycle has two phases.Depending on the type of organisms, the duration of the cell cycles varies.The first stage of interphase is called G1 phase.The final stage of interphase is called G2 phase.There are significant development processes within the cell.G2 phase is shorter than G1 phase.Most of theRNA that is synthesised during the G1 phase is mRNA.If a cell enters the G2 phase, it means that the S phase has been completed.Both phases will be controlled by cell cycle regulatory mechanisms.This is the difference between the two phases of the cell cycle.
