question 12 of

Explanation:

1. For the first sentence: The centromere is the region where sister chromatids are attached. So we use "centromere" here.
2. For the second sentence: The centrosome is the structure from which spindle fibers extend (in animal cells, it contains centrioles and is the microtubule - organizing center). So we use "centrosome" here.
3. For the third sentence: A chromosome is made up of coiled and condensed chromatin (during cell division, chromatin condenses to form visible chromosomes). So we use "chromosome" here.

Answer:

1. The centromere is the point of attachment for sister chromatids.
2. The centrosome is an area from which the spindle fibers extend.
3. The chromosome consists of coiled and condensed chromatin.
