Answer:
b. false
Explanation:
The cell cycle consists of three states: Interphase, Cell division (mitosis) and Resting.
Interphase is composed of phases G1, S and G2. during this state the cell replicates the genetic material of its chromosomes to prepare itself for cell division
In G1 the cell synthesizes mRNA and proteins that the cell will need during mitosis.
In S the cell replicates the genetic material of its chromosomes to prepare itself for cell division. At the end of this phase each chromosome is composed of two sister chromatides.
In G2 the cell grows and and more proteins synthesized for mitosis.
Mitosis is the production of two daughter cells from a sinlge one. During the entire mitosis the chromosomes are duplicated in the cell until finally, the genetic material is distributed in two cells after cytokinesis.
According to the above, it can be seen that the chromosomes in a cell that is in the cell cycle do not necessarily have sister chromatids. For example, chromosomes during G1 do not have sister chromatids.
