What is the G1 phase of the cell cycle?

Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

How long is each phase of the cell cycle?

The cell grows (more…) The duration of these cell cycle phases varies considerably in different kinds of cells. For a typical rapidly proliferating human cell with a total cycle time of 24 hours, the G1 phase might last about 11 hours, S phase about 8 hours, G2 about 4 hours, and M about 1 hour.

What occurs during the G2 phase of the cell cycle?

The last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

What do the 2 arrows represent in the cell cycle?

The mitotic phase represents the period of active division. It is further divided into the prophase, the metaphase, the anaphase, and the telophase. Hence, the first arrow (1) of the model represents the interphase while the second arrow (2) represents the mitotic phase.

How does cytarabine affect the skin?

It is also FDA approved for use with other drugs to treat acute myeloid leukemia, acute lymphoblastic leukemia and chronic myeloid leukemia. This medicine may cause a temporary loss of hair in some people. After treatment with cytarabine has ended, normal hair growth should return.

Can you kiss while on chemo?

Kissing is a wonderful way to maintain closeness with those you love and is usually okay. However, during chemotherapy and for a short time afterward, avoid open-mouth kissing where saliva is exchanged because your saliva may contain chemotherapy drugs.
