Answer:

Mitotic spindle

Explanation:

During prophase, the formation of the spindle begins. The mitotic apparatus at metaphase consists of two parts: lemon-shaped mitotic spindle and a pair of asters. Mitotic spindle consists of microtubules. There are three different types of microtubules: astral microtubules, kinetochore microtubules, and polar microtubules. The astral microtubules form the asters and radiate out from centrosome.

The kinetochore microtubules are attached to the chromosomes via kinetochores. Polar microtubules are not attached to the chromosomes. The polar microtubules from opposite poles overlap. Altogether, the mitotic spindle serves to align the chromosomes at the cell's equator to facilitate the movement of sister chromatids to opposite poles during anaphase.

Use 1 word to summarize each step for the process of translation (total: 5 words).

Molodets [167]

Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in the Figure below. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.
