Cell Cycle and Mitosis
Interphase
If the parent cell has 70 chromosomes, how many chromosomes will each daughter cell have after meiosis?
35
Spermatogonium
What phase of interphase detects and repairs DNA damage, ensuring the cell is ready to proceed to mitosis?
G2 Phase (Second Gap Period)
Homologous chromosomes line up side by side at the middle of the cell. Which stage does this describe?
Metaphase I
If there are 60 spermatogonium, how many primary spermatocytes will be produced?
30
If the parent cell has 50 chromosomes, how many chromosomes will the daughter cells have after mitosis?
50
What is the process of pairing of homologous chromosomes that happen in Prophase I?
Synapsis
If there are 30 primary oocytes, how many polar bodies will be produced after Meiosis I?
30
A cell completes DNA replication but cannot produce spindle fibers. Which stage would be affected first?
Prophase
A chromosome still consists of two sister chromatids but is moving toward one pole of the cell. Which stage is occurring?
Anaphase I
A reproductive tissue contains 40 primary spermatocytes and 40 primary oocytes, all completing meiosis. How many functional gametes will be produced altogether?
200
The daughter cells produced after cell division have different numbers of chromosomes. Which stage of mitosis most likely did not occur properly?
Anaphase
What phase of meiosis do sister chromatids separate?
Anaphase II
If there is a total of 100 gametes after spermatogenesis, how many primary oocytes and primary spermatocytes did they came from?
20 primary oocytes and 20 primary spermatocytes
