Mitosis Flashcards
chromosomes
single piece of coiled up DNA
nucleus
controls the activities of a cell and contains genetic information
genes
short length of DNA, coding for characteristics and protein synthesis
DNA
chemical making up genes
interphase
organelles and DNA replicate, mitochondria not visible
prophase
DNA becomes shorter and thicker, becoming pairs of chromatids
metaphase
pairs of chromosomes line up at equator
anaphase
centrioles send spindle fibres to equator, pulling chromosomes and their copies away from each other, to different poles
mitosis
nucleus and nuclear membrane split
mitosis (definition)
division of the nucleus, forming two genetically identical cells
significance of mitosis
growth and repair of cells/ tissues
telophase/ cytokinesis
cell membrane and cytoplasm split, leaving two genetically identical cells
