Questions with Correct Answers
Where is mitosis in the cell cycle? - Answer-Before cytokinesis and after interphase
What three phases of the cell cycle are considered interphase? - Answer-G1, S, G2
How many chromatids are in each replicated chromosome? - Answer-2
How many single chromosomes are in each of the new cells of telophase? - Answer-4
Write a grammatically correct sentence that explains what a chromosome is and why it
is important. - Answer-A chromosome is made up of DNA and carries the genes needed
by the cell to make proteins.
Use a complete sentence to describe what the new cells in telophase might contain if
replication of chromosomes did not occur before cytokinesis. - Answer-The cells
wouldn't contain a copy of each chromosome
In which phase of mitosis do you see the spindle fibers forming? - Answer-Prophase
At what phase of mitosis do the replicated chromosomes (sister chromatids) separate? -
Answer-Anaphase
In which phase do you see that spindle fibers have disappeared? - Answer-Telophase
Look at metaphase & anaphase. Suggest the purpose of the spindle fibers during
mitosis. - Answer-Spindle fibers help make sure each daughter cell gets a complete set
of chromosomes by lining them up and separating them.
Describe what happens to the nuclear membrane after prophase - Answer-It dissolves
away
Explain why it is necessary that the nuclear membrane disintegrates during mitosis. -
Answer-So the chromosomes can attach to spindle fibers, line up on the metaphase
plate and separate evenly into anaphase
At what point during mitosis has the nuclear membrane reformed? - Answer-telophase
What is actually dividing during cytokinesis - Answer-cytoplasm (cell membrane divides)
, Cellular division has two parts- mitosis is the division of the nucleus and cytokinesis is
the division of the cell into two new cells. Explain why mitosis has to come before
cytokinesis and the cell cycle. - Answer-To e sure that each daughter cell gets a
complete set of chromosomes.
Gametes - Answer-Sex cells
Egg - Answer-Females sex cell
Sperm - Answer-Male sex cell
Haploid number - Answer-Number of chromosomes found in a gamete
Diploid Number - Answer-Number of chromosomes found in the body cells of an
organism
The diploid number is twice its haploid number
Meiosis - Answer-type of cell division that produces gametes
Polar bodies - Answer-In meiosis, one cell receives most of the cytoplasm, making it
much larger than the peter three cells. The large cell becomes the female gamete or an
egg cell, the three smaller cells are called polar bodies and are not involved in sexual
reproduction
If something goes wrong during Meiosis - Answer-The parent cell does not separate
evenly, causing a daughter cell to have an abnormal number of chromosomes. If this
gamete joins with a normal gamete during sexual reproduction, the new cell that forms
lacks the diploid number. An organism that develops from this cell will have a genetic
disorder.
In what type of organs are cells that enter Meiosis I found? - Answer-sex cells
Considering what you know already know about mitosis in cells, what event must take
place during interphase before a cell precedes to division? - Answer-DNA replication
What two structures make up a single replicated chromosome? - Answer-sister
chromatids
How many replicated chromosomes does the cell contain during prophase? - Answer-4
At which stage in Meiosis I do the pairs of homologous chromosomes come together? -
Answer-Late Phase 1
Once the chromosomes have formed a pair, what are they called? - Answer-Tetrads
At the end of meiosis I, two cells have been produced. How many replicated
chromosomes are in each of these cells? - Answer-2
