Document Summary

Passes genetic information to the next generation. Long, complex series of cell division required. To produce two genetically identical daughter cells. Two complex copies accurately distributed between daughter cells. Recover from m phase, prepare for s phase. Deposited at many positions along the sister chromatids during dna replication. Contains smc proteins (structural and maintenance of chromosomes) Species variation: humans have 23 pairs of homologous chromosomes. Klinefelter syndrome, caused by an extra x chromosome, The most common sex chromosome abnormality in males. Turner syndrome, caused by missed one x chromosome in females. Chronic myelogenous leukaemia, a classic 9:22 translocation that is diagnostic of that disease. Cell confirms the number of chromosomes and the organelles present. Three chromosomes are shown, each with two sister chromatids. Chromosomes replicated in s phase condense (two sister chromatids) Mitotic spindle assemble between the two centrosomes. Chromosome attach to spindle microtubules via kinetochores. Chromosomes are aligned at the equator of the spindle, midway between the spindle poles.
