ETHC 210 Lab Activity 1 Liberty
- Chromosomes are constructed of DNA and ____Protein_______.
- Humans are diploid, meaning they have two sets of chromosomes numbering _______46______ total.
- When chromosomes are duplicated, they look like an “X”-shaped structure. The two strands of chromosomes are attached at the ______centromere________.
- In humans and all creatures constructed of eukaryotic cells, the DNA always resides in the ___Nucleus______.
- The yellow and red chromosomes you constructed are similar, and therefore, both of them together are considered to be a ____homologous_____ pair.
- In this assignment, you constructed the first phase of mitosis called___interphase__.
- During both mitosis and meiosis, chromosomes are aligned and pulled apart with the help of a cytoskeletal fiber called __mitotic spindle____.
- Microtubules or spindle fibers attach to the centromeres of the chromosomes and pull them apart during mitosis. The microtubules radiate from structures you included in your simulation called _____centrioles______.
- In order for the chromosomes to be separated successfully during mitosis or meiosis, the membrane of the __nucleus______ must be disassembled.
- Meiosis and mitosis are part of a nuclear division process called __Cytokinesis______.
