What phase does the cell growing and making proteins?
During the S phase, the cell dedicates its time to replicating its DNA. The S phase is named for the synthesis of DNA. The G phases are needed for increasing proteins and cellular organelles, and are known for cellular growth. The M phase is also known as mitosis.
During which phase does the cell grow in size?
Interphase is the longest phase of the cell cycle. During this phase the cell grows to its maximum size, performs its normal cellular functions, replicates its DNA, and prepares for cell division. This stage is divided into three parts: G1, G2 and S phases.
Where does cell growth occur in the cell cycle?
For a typical dividing mammalian cell, growth occurs in the G 1 phase of the cell cycle and is tightly coordinated with S phase (DNA synthesis) and M phase (mitosis). The combined influence of growth factors, hormones, and nutrient availability provides the external cues for cells to grow.
How long does the G1 phase of cell growth last?
Between G1, S, and G2 phases, cells will vary the most in their duration of the G1 phase. It is here that a cell might spend a couple of hours, or many days. The S phase typically lasts between 8-10 hours and the G2 phase approximately 5 hours.
How does cell division increase the potential for growth?
Cell division alone does not constitute growth but rather increases the potential for growth by increasing the number of cells that can subsequently undergo expansion. Growth itself relies on the process of cell expansion and, in plants, this mechanism is highly dependent on the mechanical properties of the cell wall.
What are the two major phases of the cell cycle?
Figure 3.5.1 – Cell Cycle: The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G 1, S, and G 2 phases. After the synthesis phase, the cell proceeds through the G2 phase.
