Question

test cell growth and division
drag the words to complete the sentences.
centromere
centrosome
chromosome
the is the point of attachment for sister chromatids.
the is an area from which the spindle fibers extend.
the consists of coiled and condensed chromatin.

Explanation:

1. For the first sentence: The centromere is the region where sister chromatids are attached. So we drag "centromere" to the first blank.
2. For the second sentence: The centrosome is the structure from which spindle fibers extend during cell division. So we drag "centrosome" to the second blank.
3. For the third sentence: A chromosome is made up of coiled and condensed chromatin. So we drag "chromosome" to the third blank.

Answer:

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