Respuesta :
A G1 cell has half as much DNA as some of the other cells in a mitotically active tissue.
Why does G1 cell has half DNA ?
- Mitotically active tissue is tissue that is actively dividing cells, such as the root tip of a plant or a growing embryo.
- The cell cycle comprises two phases : - the interphase : during which the cell rests and expands - the M phase : during which cell division occurs.
- The DNA is copied and double the quantity of DNA than the mother cell is created during the S phase of the interphase so that the genetic material is evenly split amongst the daughter cells following the division.
- If a cell is mitotically active, it will undergo a continual synthesis phase after each cell division in order to furnish the daughter cell with the same quantity of DNA as the mother cell.
- So, if a cell in a mitotically active tissue contains half the DNA of the other cells in the tissue, the cell will be in G1, which occurs after the M phase and before the S phase, where the DNA will replicate.
What are the Primary Functions of the G1 Phase?
- Because this is the time when a cell grows, the G1 phase is also known as the growth phase.
- During this phase, the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division.
- The duration of the G1 phase is variable and it often depends on the nutrients that are available to a cell.
- Cells produce the most proteins during the G1 phase.
