WebThe tips of chromosomes contain repeated sequences that shorten with each mitotic division. These regions are called _____. A) p arms B) centromeres C) q arms D) telomeres WebThe chromosomes are bound tightly together and in perfect alignment by a protein lattice called a synaptonemal complex and by cohesin proteins at the centromere. Located at intervals along the synaptonemal complex are large protein assemblies called recombination nodules.
Ends of chromosomes protected by stacked, coiled DNA caps
WebMicrotubules that bind a chromosome are called kinetochore microtubules. Microtubules that don’t bind to kinetochores can grab on to microtubules from the opposite pole, stabilizing the spindle. More microtubules extend from each centrosome towards the edge of the cell, forming a structure called the aster. WebMeiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. purity vitamins
