Students have asked these similar questions
When the cell is actually dividing is called the S phase where each chromosome in the cell consists
of two identical sister. It includes two overlapping stages, mitosis and cytokinesis.
Select one:
True
False
Which event occurs in S-phase?
prastrca
Mitotic spindle is created.
O Normal growth and cell function
Energy stores are replenished
Karyokinesis
None of the above
Which of the following is NOT a checkpoint that controls the progression of cell cycle?
The metaphase checkpoint determines if all chromosomes are attached to the spindle apparatus
Cytokinesis involves the formation of cleavage furrow to separate the cells
The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated
Cyclins and cyclin dependent kinases are protejns that are responsible for advancing a cell through the phases of the cell cycle

When the S phase of the cell cycle is finished, a cell has twice as many chromatids as the number of chromosomes in the G1 phase In actively dividing cells, the S and G2 phases are collectively known as interphase The phases of the cell cycle are G1, S, and M phases The cell cycle is a sequence of replications and divisions that produces new cellsarrow_forwardChoose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.arrow_forward
