The hox6 paralogs begin to be expressed in somites just posterior to the boundary between the somites that give rise to cervical (neck) and thoracic (rib forming) vertebrae. expression of hox6 paralogs extends into the somites that give rise to the lumbar vertebrae. if all three paralogs of hox6 are mutated, which change would you expect:

answer; /// i believe that the correct answer is (50%);

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.
