Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. some textbooks list five, breaking prophase into an early phase and a late phase. which of these has occurred by the end of prophase?

Explanation:

At the ending of pro phase or late prophase, the mitotic spindle begins to capture and organize the chromosomes.

* The chromosomes have finished condensing and are now very compact.

* The nuclear envelope is broken down and the chromosomes are released.

* The mitotic spindle grows more, and some of the microtubules start to “capture” chromosomes.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
