Question

Compare between metaphase l and metaphase ll of meiosis?

Answer 1

Hint: Metaphase is one of the four stages of nuclear division in eukaryotic cells. The four stages of cell division in eukaryotes include prophase, metaphase, anaphase, and telophase. During metaphase, chromosomes of a cell are condensed to their second most condensed stage. Membrane nucleus breaks down, and the condensed chromosomes align in the cell equator in metaphase.

Complete step by step answer:
Comparison between metaphase l and metaphase ll

METAPHASE l	METAPHASE ll
Metaphase l process is seen in meiosis l	Metaphase ll is seen in meiosis ll
In this process, the tetrads are arranged at the metaphase equator	In this process, a single chromosome is arranged at the metaphase equator
In this process, the microtubules of one pole are attached to kinetochores of one of two chromosomes facing to the same pole	In this process, the microtubules are attached to kinetochores of the centromere on either side of a single chromosome.
single chromosomes move towards the opposite poles at the completion of this process, and in starting of anaphase l	One pair of sister chromatids move towards the opposing poles at anaphase 2
In this process, the metaphase plate is arranged in equidistant to the opposite poles.	In this process, the metaphase plate rotates 90 degrees compared to metaphase l

Note: The cell division cell goes through four stages namely PROPHASE, METAPHASE, ANAPHASE, TELOPHASE.
In meiosis, the prophase is considered as prophase i and prophase ii. The prophase l consists of five different sub-phases namely Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. The remaining stages do not contain any sub-phases.
The meiosis ii is quite similar to the mitosis process with the same number of stages and processes.
