ЧТО ОЗНАЧАЕТ СЛОВО PROPHASE
профаза
Профаза, от древнегреческого πρό и φάσις, представляет собой стадию митоза, в которой хроматин конденсируется в двойные стержнеобразные структуры, называемые хромосомами, в которых становится заметным хроматин. Этот процесс, называемый конденсацией хроматина, связан с комплексом конденсана. Поскольку генетический материал был реплицирован в предшествующем интерфазе клеточного цикла, в клетке имеется две идентичные копии каждой хромосомы. Эти копии называются сестринскими хроматидами, и они прикреплены друг к другу с элементом ДНК, присутствующим на каждой хромосоме, называемой центромером. Также во время профазы окрашивание giemsa может быть применено для выявления G-полос в хромосомах. Важной органелой в митозе является центросома, центр организации микротрубочек в метазоанах. Во время профазы две центросомы, которые реплицируются независимо от митоза, увеличивают активность микротрубочек за счет рекрутирования γ-тубулина. Центросомы будут оттеснены на противоположные концы ядра клетки под действием молекулярных моторов, действующих на микротрубочки. В принципе, хроматин в ядре обматывается хромосомами.

Telomeres associate with the nuclear envelope, cluster and accumulate adjacent to the centrosome to form the chromosome bouquet in meiotic prophase.
As preprophase progresses into prophase, nuclear envelope-associated
microtubules (i.e., perinuclear microtubules) increase in number and transition
from random or parallel orientations to the plane of the PPB to tangential
orientations ...
