Questão 22
Questão
Cell spend most of their time in [blank_start]interphase[blank_end].
Questão 23
Questão
Interphase consists of [blank_start]three[blank_end] parts: [blank_start]G1[blank_end], [blank_start]S[blank_end], and [blank_start]G2[blank_end].
Questão 24
Questão
During prophase the centrioles [blank_start]separate[blank_end] and [blank_start]spindle[blank_end] begins to form. The chromosomes begin to [blank_start]condense[blank_end] and the [blank_start]nuclear[blank_end] [blank_start]membrane[blank_end] begins to break down.
Responda
-
separate
-
spindle
-
condense
-
nuclear
-
membrane
Questão 25
Questão
During metaphase the chromosomes [blank_start]line[blank_end] up single file in the [blank_start]middle[blank_end] of the cell. The spindle fibers attach to the [blank_start]centromere[blank_end] region.
Questão 26
Questão
During anaphase the spindle fibers begin to pull on the [blank_start]centromeres[blank_end] causing the sister chromatids to pull [blank_start]apart[blank_end] and move to [blank_start]opposite[blank_end] poles of the cell.
