30 Questions
During which phase of mitosis do the cell's chromosomes align in the center of the dividing cell?
Karyokinesis
What is the correct chronological order of sub phases during mitosis?
Prophase, Metaphase, Anaphase, Telophase
What occurs during prophase of mitosis?
Nuclear envelope disintegrates
Which phase involves the division of the cell's cytoplasm?
Karyokinesis
In which phase does chromatin condense to form chromosomes?
Prophase
What is the main outcome of mitosis in terms of genetic material?
The daughter cells have genetically identical DNA to the mother cell.
During which stage of cell division do chromosomes separate or move towards opposite poles of the cell?
Anaphase
What is the main outcome of telophase in mitosis?
Separation of duplicated genetic material into two identical daughter cells
How many daughter cells are formed from meiosis?
Four
Which process is essential for sexual reproduction and the production of haploid gametes?
Meiosis
What is the first stage of prophase I in meiosis called?
Leptotene
After which stage do replicated, paired chromosomes start to move to opposite sides of the cell?
Anaphase
What is the main difference between vegetative cell division and reproductive cell division?
Vegetative cell division creates genetically identical daughter cells, while reproductive cell division creates egg and sperm cells.
What type of cells does mitosis create?
Diploid cells with 46 chromosomes
How does meiosis differ from mitosis in terms of chromosome number in daughter cells?
Meiosis results in haploid daughter cells with 23 chromosomes, while mitosis results in diploid daughter cells with 46 chromosomes.
Which statement best describes the process of mitosis?
Equational division resulting in genetically identical daughter cells.
What is the goal of vegetative cell division?
To produce genetically similar daughter cells for growth and repair.
In which type of cell division does the DNA replication and growth take place during the formation of new daughter cells?
Mitosis
What is the distinguishing feature of the pachytene stage in meiosis prophase-1?
Formation of tetrads with visible chromatids
What is the main characteristic of the leptotene stage in meiosis prophase-1?
Visibility of thread-like chromosome structures
Which stage follows zygotene but precedes diplotene in meiosis prophase-1?
Pachytene
What occurs during diakinesis, the fifth stage of prophase-1 in meiosis?
Homologous paired chromosomes begin to separate
At which stage do homologous chromosomes begin pairing in meiosis prophase-1?
Zygotene
What defines the diplotene stage of meiosis prophase-1?
Separation of homologous chromosomes and chiasmata formation
What is the outcome of Telophase I in meiosis?
Formation of two haploid daughter cells
What is the main purpose of cytokinesis in cell division?
To divide a cell into two daughter cells
What occurs during Metaphase II of meiosis?
Chromosomes move to the equatorial plate and attach to spindle fibers
How many daughter cells are produced after Meiosis II?
Four
What is the ploidy level of each daughter cell after Telophase II?
Haploid
When does cytokinesis occur in relation to mitosis and meiosis?
Concurrently with nuclear division
