Meiosis is divided into meiosis I and meiosis II. Like mitosis, the onset of meiosis I is preceded by all 46 of a cell's chromosomes replicating. In meiosis, however, after the nuclear membrane is dissolved in prophase, the homologous chromosomes pair off, side by side, with the homolog d...
What is the best description of chromosomes by the end of metaphase II of meiosis? How does meiosis get its diploid cell? What would happen if only mitosis occurred in the ovaries and testes instead of meiosis? Which process must occur before mitosis and meiosis can occur? Mitosis occurs in...
What is the purpose of mitosis? what would happen if cells did not undergo mitosis?Organization of Living Things:Cells are the basic units of life and make up all living things. Single celled organisms consist of only one cell, but multicellular organisms consist of many c...
Meiosis produces which cell type? What must happen before meiosis can begin? What is produced as a result of meiosis? What are the unique events that occur during meiosis? How do mitosis and meiosis differ? How does the process of crossing over during meiosis increase genetic diversity? What ...
Occasionally, two sperm are known to fertilize a single egg; this 'double fertilization' is thought to happen in about 1% of human conceptions. An embryo created this way doesn't usually survive, but a few cases are known to have made it — these children are chimaeras of cells with X ...
Explain what would happen if Interphase did occur between Meiosis I and II. What would happen if cell division becomes uncontrolled? Explain and describe what are the two main phases of the cell cycle? What must happen before Mitosis can begin? Explain mitosis. What are the theories of the ...
The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In eukaryotic cells, DNA replication occurs during the S-phase of the cell cycle. During S-phase, RNA transcription and protein translation are largely limited to the ...
Nondisjunction may occur any time a cell divides, so it can happen during mitosis, meiosis I, or meiosis II. Conditions associated with nondisjunction include mosaicism, Down syndrome, Turner syndrome, and Klinefelter syndrome. Types of Nondisjunction ...
Because we know all atoms to perform all the time a completely disorderly heat motion, which, so to speak, opposes itself to their orderly behaviour and does not allow the events that happen between a small number of atoms to enrol themselves according to any recognizable laws. Only in the ...
What must happen before meiosis can begin? What happens in meiosis I that does not occur in meiosis II? In what stage of meiosis does trisomy 21 occur? In meiosis, what makes up a tetrad? What is chiasmata in meiosis? How do you determine when nondisjunction occurs? What does meiosis ...
