Mitosis and Meiosis

The following picture is anaphase in the number ...

• 1

• 2

• 3

• 4

Answer explanation

The stages below are the stages of division in the prophase I process of meiosis and take place in several sub-phases, namely:

(1) Pakiten

(2) Diakinesis

(3) Diploten

(4) Leptoten

(5) Zygotene

Which is the correct sequence of the process of Prophase I of meiosis. . .

• 4-1-5-3-2

• 4-5-3-2-1

• 4-3-2-1-5

• 4-5-1-3-2

The events that occur in prophase of meiosis I are...

• Splitting the centromere into 2

• The melting of the core wall

• Chromatin threads are formed

• The chromatids move towards the poles

Answer explanation

Prophase :

Whatever the type, mitosis, miosis 1, meiosis 2 have the same characteristics, namely and the order is easy to understand

- chromatin shortens and thickens into chromosomes

- centrosome divides into 2 centrioles, each centriole

go to the poles (remember it's not the chromosomes that are polar)

- nuclear membrane is missing nucleus (nucleolus)

- chromosomes are arranged in a mess (irregular/meaning they are everywhere)

The longest phase of cell reproduction so that the greatest energy is required

The correct label of the spermatogenesis picture below is…

• 1 spermatogonium, 4 spermatid

• 1 spermatid, 3 spermatosit

• 1 spermatogonium, 3 spermatocyte

• 1 spermatogonium, 4 sperm

Answer explanation

The image below shows the phases…

Answer explanation

Remember!

Metaphase always symbolized by the chromosomes lined in the equator cell~

In the oogenesis diagram below, the primary oocyte is shown in the number …

• 1

• 2

• 3

• 4

• 5

Answer explanation

The place where meiosis occurs is...

• 1 and 2

• 2 and 3

• 3 and 4

• 4 and 5

• 5 and 6

Answer explanation

The stages shown in Figure A-B-C in a row are…

• Prophase I, Metaphase I, Anaphase I

• Metaphase II, Anaphase II, Prophase II

• Anaphase I, Prophase II, Metaphase II

• Metaphase I, Prophase I, Anaphase I

• Metaphase I, Prophase II, Anaphase II

Answer explanation

Place: Autosomatic cell

Purpose: Growth and to regulate the behavior of chromosomes

Ploidization: n mother cell = n daughter cell

There is an interphase before cleavage is carried out

Cell trait: Diploid

Number of division stages: Only one division stage in one cell division cycle

What is the cell division mentioned above?

• Mitosis

• Meiosis

At which of the following stages of cell division, the separation of chromatids and their movement to opposite poles occur?

• Prophase

• Telophase

• Anaphase

• Metaphase

Answer explanation

In anaphase, there is a shortening of the spindle microtubules. Each chromosome is pulled along by its centromere the two sister chromatids of each chromosome are pulled apart by the spindle and dragged by their kinetochores toward opposite poles of the cell.
