Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this genel is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene? Abnormal cells would continue to divide. Damaged cells would attack healthy cells. O Affected cells would produce more proteins. Germ cells would undergo only one meiotic division.

Abnormal cells will continue to divide

Explanation:

I’m reviewing with my teacher.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

d. planting trees

the trees take in carbon to make oxygen.
