Smoke/Fumes from oven range GE Profile. I just bought a house that has a GE profile convection oven. The house is 16 years old so I am guessing so is the oven. When we started the oven the first time at 350, whole lot of smoke came out and the smoke alarms went off.
1 The centromere (centron = middle, meros = part) is the region of the chromosome where the chromatids that arise from replication are held together. 2  The centromere hosts the kinetochore, a protein complex where the spindle filaments attach during mitosis or meiosis.
Report Abuse. The simplest answer is the microtubules that attach to the centromeres of the chromosomes. In the first division the chromatids are not separated allowing the separation of the homologous pairs of chromosomes.The second division the chromatids are separated forming four haploid daughter cells.ach one forms an aster of microtubules that connect to the centromere on each side of the paired chromosomes. This way each half of a paired chromosome is pulled to a pole before cell division. This works on meiosis I tetrads and on meiosis II dyads.
