If a cell stops at the G1 checkpoint, this is most likely due to what problem?
The DNA has not finished replicating.
The chromosomes are not aligned properly.
There is DNA damage.
The cell is cancerous.
There is no problem. The cell normally stops at the G1 checkpoint.
In plant cells, what is responsible for organizing the spindle?
Centrosomes
Centrioles
Microtubules
Asters
Centromeres
The only haploid stage in the animal life cycle is the gamete.
True
False
Which of the following is a correct association?
Cytokinesis-division of the chromosomes
Centromere-forms spindle fibers during prophase
Haploid-having two copies of each chromosome
Sister chromatids-two identical chromosome strands still attached at the centromere
Mitosis-when a cell duplicates and then divides twice to reduce chromosome number by half
The nuclear membrane reappears in mitosis during
Interphase.
Prophase.
Metaphase.
Anaphase.
Telophase.
If their sperm contain 32 chromosomes, how many chromosomes do diploid cells in horses contain?
46
23
32
64
128
Microtubules found in spindle fibers are capable of assembling and disassembling.
True
False
The formation of sperm is termed
Oogenesis.
Homologous formation.
Spermatogenesis.
Gametogenesis
Mitosis.
Crossing-over is the only factor that is responsible for the variation that exists between offspring of one set of parents.
True
False
In humans, the diploid number of chromosomes is
20.
46.
23.
Variable depending on whether male or female.
92.
Homologous chromosomes are genetically identical to each other.
True
False
The cell cycle consists of
Mitosis and interphase.
Meiosis and interphase.
Prophase and interphase.
Metaphase and interphase.
Changes from a haploid to a diploid state.
Which of the following processes occurs in both mitosis and meiosis?
Homologous chromosomes pair up
Two series of cell divisions
Sister chromosomes separating during the second division
Single chromosomes line up along the metaphase plate
Fertilization restores the diploid number
Which of the following events would be controlled by an external signal?
Cell division
Prophase proceeding into metaphase
The chromosomes aligning at the equatorial plane before the cell begins anaphase
Initiating S phase
All of the answer choices are controlled by an external signal.
The second meiotic division is essentially a mitotic division except for the fact that the cells produced are
Haploid.
Diploid.
Polyploid.
Autosomal.
Somatic.
Mitotic division is the normal process of cell reproduction to build and maintain the body of an organism, while meiosis takes place only in the formation of gametes for reproduction.
True
False
