CH 18 Flashcards
When a cell undergoes mitosis what happens to the genes?
the daughter cells have identical genes, and these genes are identical to those of the ?parent? cells that produced them.
What happens to the organelles when a eukaryotic cell divides?
the daughter cells receive enough of the organelles to start up the new cells and produce additional organelles as needed.
In mitosis, if a ?parent? cell has 16 chromosomes, each daughter cell will have how many chromosomes?
- 16
What is the term describes cells with a double set of genetic information
- diploid.
Give an example of a cell that is NOT a somatic cell)
Sperm, egg
What is the chromosome number in human body cells?
- 46.
Chromatids that are attached at the centromere are called what kind of chromatids?
- sister
DNA replication occurs during what phase(s)?
- S phase
What is the number of chromatids present in a duplicated chromosome?
- 2.
Write out the proper sequence of phases for mitosis.
prophase, metaphase, anaphase, telophase
What is the name of the phase during which the chromosomes are aligned at the spindle equator ?
metaphase.
At the end of which phase is the chromosomes condensed?
prophase.
The spindle apparatus becomes visible during what phase
prophase.
The chromosomes detach from one another and become visibly separated during what phase?
anaphase.
The chromosomes are moving to opposite poles during what phase?
anaphase.
The chromosomes have arrived at opposite poles during during?
telophase.
The nuclear membrane reforms during what phase?
telophase.
Strictly speaking, mitosis and meiosis are divisions of which part(s) of a cell?
nucleus and chromosomes.
In which of the stages below does the chromosome consist of two chromatids?
metaphase and prophase
The distribution of cytoplasm to daughter cells is accomplished during what phase?
cytokinesis (cytoplasmic division).
