1. Zigote akan mengalami pembelan sel, jika mengalami lima kali pembelahan akan  menghasilkan berapa banyak sel pada awal embrio?

Explanation

The question is asking how many cells will be produced after five divisions of a zygote. Each division doubles the number of cells, so after the first division, there will be 2 cells, after the second division there will be 4 cells, after the third division there will be 8 cells, after the fourth division there will be 16 cells, and after the fifth division there will be 32 cells. Therefore, the correct answer is 32.

2. Sentromer adalah daerah di mana :

Explanation

The correct answer is "kromatid tetap melekat satu sama lain sampai anafase." This answer is correct because centromeres are responsible for holding sister chromatids together until they separate during anaphase of mitosis. The centromere is a specialized region on the chromosome where spindle fibers attach and facilitate the separation of chromatids. So, until anaphase, the chromatids remain attached to each other at the centromere.

3. Untuk protista baru berkembang , apa yang akan menjadi keuntungan dari menggunakan eukariot seperti sel divisi daripada pembelahan biner ?

Explanation

Using eukaryotic cell division, such as mitosis, would provide the advantage of allowing for orderly and efficient separation of linear chromosomes. This means that during cell division, the chromosomes are properly distributed to each daughter cell, ensuring the genetic material is accurately passed on. In contrast, binary fission, a form of cell division used by prokaryotes, does not allow for the same level of precision in chromosome separation. Therefore, using eukaryotic cell division would be beneficial for the development of new protists.

Submit
4. Apa yang dimaksud kromatid ?

Explanation

Kromatid adalah daerah khusus yang memegang dua sentromer bersama-sama. Kromatid terbentuk saat kromosom mereplikasi dirinya sendiri selama fase S dari siklus sel. Setelah replikasi terjadi, dua kromatid yang identik terhubung oleh sentromer dan membentuk kromosom yang terlihat seperti "X". Kromatid kemudian akan dipisahkan selama pembelahan sel sehingga setiap sel anak menerima satu kromatid.

5. Bagaimana sel anak pada akhir mitosis dan sitokinesis dibandingkan dengan orang tua mereka
sel ketika G1 dari siklus sel ?

Explanation

During mitosis and cytokinesis, the parent cell divides into two identical daughter cells. This means that the daughter cells will have the same number of chromosomes and the same amount of DNA as the parent cell. Therefore, the correct answer is "Sel-sel anak memiliki jumlah kromosom yang sama dan jumlah yang sama DNA."

Submit
6. Sentriol mulai bergerak terpisah pada sel hewan terjadi pada ?

Explanation

During prophase, the centrioles in animal cells start to move apart. This is the first stage of mitosis, where the chromosomes condense and become visible. The nuclear membrane also starts to break down during prophase. Therefore, the correct answer is profase.

Submit
7. Sentriol mulai bergerak terpisah pada sel hewan terjadi pada ?

Explanation

During the prophase stage of mitosis, the centrioles start to move apart and migrate to opposite poles of the cell. This is an important step in cell division as it helps to form the spindle fibers that will eventually separate the chromosomes during anaphase. Therefore, the correct answer is profase.

Submit
8. Dua centrosomes berada pada kutub yang berlawanan dari sel?

Explanation

During prometaphase, the two centrosomes move to opposite poles of the cell. This is the stage where the nuclear envelope breaks down, allowing the microtubules from the centrosomes to attach to the chromosomes. The chromosomes then start to align at the center of the cell. Therefore, it can be inferred that during prometaphase, the two centrosomes are located at opposite poles of the cell.

Submit
9. Yang terpanjang dari tahapan mitosis?

Explanation

The correct answer is metafase. Metafase is the stage in mitosis where the chromosomes line up along the equatorial plate of the cell. This is the longest stage of mitosis and is characterized by the chromosomes being fully condensed and attached to the spindle fibers. During metafase, the chromosomes are at their most visible and organized state, preparing for the separation of sister chromatids in the subsequent stage of anafase.

Submit
10. Jika sel-sel dalam proses pembelahan diberi colchicine, obat yangmengganggu fungsi aparatus gelendong, menyebabkan mutasi pada mitosis : 

Explanation

Colchicine is a drug that disrupts the function of the spindle apparatus, which is responsible for separating chromosomes during mitosis. When cells undergoing division are treated with colchicine, it can cause mutations in the process of metaphase, where the chromosomes align along the equatorial plane of the cell. This disruption can lead to abnormal chromosome segregation and potentially result in genetic mutations.
