Human carcinoembryonic antigen (CEACAM6)
This gene codes for a protein that is located in the extracellular matrix. This protein is involved with cell cycle regulation, particularly with adhesion between cells. It is thought to be a proto-oncogene. When over-expressed, it becomes an oncogene, because it leads to unregulated cell division and inhibits cellular death T/F

True.

Explanation:

Cancer may be defined as the uncontrolled growth of the cell cycle that leads to the abnormal cell formation. The cancerous cell require less time to grow as the normal cells and they are immortal in nature.

The mutation in the tumor suppressor gene or in the proto oncogene leads to the formation of the cancerous cells. The carcinoembryonic antigen (CEACAM6) acts as proto oncogene and gain of function mutation will change this proto oncogene into oncogene. This leads to uncontrolled cell growth.

Thus, the correct answer is true.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

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
