Question

name: cardon date: 19/23/25 cell division: reinforcement mitosis nucleus interphase telophase spindle diploid prophase cytokinesis haploid centromeres metaphase chromatids dna chromosome anaphase centrioles 1. these structures are found in the nucleus of dividing cells, they appear x - shaped 2. a chromosome is made of two identical sister 3. chromosomes are made of wrapped around proteins. 4. chromosomes are found in the of the cell 5. sister chromatids are held together by 6. body cells that contain the full number of chromosomes, 46 in humans, are called 7. sex cells that contain only half the number of chromosomes are called 8. during this stage of the cell cycle, the cell is copying dna and performing cell functions: 9. during this stage of mitosis, chromosomes line up along the equator: 10. during this stage of mitosis, chromatids separate and move to opposite sides: 11. during this stage of mitosis, dna condenses and forms chromosomes: 12. during this stage of mitosis, the nuclear membrane forms in each new cell: 13. during mitosis, this structure moves individual chromosomes: 14. this pair of structures anchors the spindle: 15. the process by which the nucleus divides into two new nuclei is called: 16. the process by which the cell splits into two new daughter cells is called:

Explanation:

1. Chromosomes are X - shaped structures in the nucleus of dividing cells.
2. A chromosome has two sister chromatids.
3. Chromosomes are made of DNA and proteins.
4. Chromosomes are in the nucleus.
5. Centromeres hold sister chromatids.
6. Diploid cells have the full chromosome number (e.g., 46 in humans).
7. Haploid cells have half the chromosome number.
8. In interphase, the cell copies DNA and functions.
9. In metaphase, chromosomes line up at the equator.
10. In anaphase, chromatids separate.
11. In prophase, DNA condenses to form chromosomes.
12. In telophase, the nuclear membrane forms.
13. The spindle moves chromosomes.
14. Centrioles anchor the spindle.
15. Mitosis is nuclear division.
16. Cytokinesis is cell splitting.
