Go Phase The S phase is characterized by… DNA replication To ensure everything happens in the cell cycle correctly, there are multiple.. checkpoints At the beginning of mitosis, the cell is called the __________ cell. Parent In anaphase of mitosis, the __________ separate. Sister chromatids (chromosomes) The phase of mitosis that is characterized by the arrangement of all chromosomes along the center of the cell is called… metaphase The products of mitosis are ______ cells that are ________. 2 (identical)diploid cells Give an example of a cell that undergoes mitosis. Somatic (body) cells When two pairs of homologous chromosomes line up in Prophase I of meiosis, it is called a _________. tetrad Homologous chromosomes move to the middle and line up next to each other… Metaphase I The products of meiosis are ________ cells that are _______. 4 (different) haploid cells The phases of meiosis are the same as mitosis except that… Meiosis produces 4 haploid cells instead of 2 diploid cells. The daughter cells of meiosis are not identical to mother cell. Crossing over occurs… During prophase I Tightly coiled DNA and histone protein is referred to as a … chromosomes A pair of similarly shaped chromosomes are called_____ Homologous chromosomes The point at which two chromatids are attached to each other in a chromosome is called a… centromere Homologous chromosomes are pairs of chromosomes containing genes that code for ______ traits The same In humans, the X and Y chromosome are called the: Sex chromosomes After telophase, __________ happens and the cytoplasm divides in half. cytokinesis During prophase, the nucleus… Breaks down The process by which prokaryotes (bacteria) reproduce… Binary fission Normal cells become cancer when… Cells are not responding normally to control mechanism, regulation is lost, and the cell continuously divides. How many chromosomes are in the body cell of an organism that has a haploid number of 15? 30
