Which of the following is NOT correct
answer about telophase of mitosis:
The mitotic spindle is formed in this
phase
Two new nuclei form, and two sets of
chromosomes
Nuclear membrane and nucleoid
reappear in this phase
The enzyme aminoacyl TRNA synthetase
charges the
TRNA molecules with the correct amino
acids
FRNA molecules with the correct amino
acids
MRNA molecules with the correct amino
acids
Select the phase of the cell cycle depicted in the image below where new membranes form around the daughter nuclei and the chromosomes are separated.
telophase
interphase
prophase
anaphase
metaphase
mitotic index:
Interphase = 80 cells
Prophase = 9 cells
Metaphase = 5 cells
Anaphase = 2 cells
Telophase = 4 cells
The average duration for the cell cycle in this culture is known to be 20 hours. Use the data above to work out the duration of interphase and metaphase.
