C-met is an oncogene that contributes to the development of certain cancers by triggering cell division and tumor growth. in a 2009 article, yan and colleagues found regions in the 3' untranslated region of c-met mrna complementary to microrna-1/206. in addition, higher levels of microrna-1/206 were associated with slower cell proliferation. what is a likely explanation for the inverse correlation between microrna-1/206 and cell proliferation?

G1 phase cell cycle arrest and apoptosis

Explanation:

According to Yan and colleagues 2009 article, cells that were transfected with microRNA-1/206 showed cell cycle arrest at the G1 phase and showed an increase in apoptosis (programmed cell death) which is important for synthesis of mRNA and protein. These processes have a direct effect on cell proliferation by decreasing it.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
