TRUE OR FALSE

1. One of two identical"sister" parts of a copied chromosome is called a chromatid
2.The final phase of mitosis in which the nuclear envelope re-forms is called anaphase.
3.Divsion of the cytoplasm takes place during prophase.

Sir, it appears I died.

1. False.

To determine the accuracy of this statement, we need to understand the terminology related to chromosome structure. A chromatid refers to one of the two identical copies of a chromosome that are joined together by a structure called a centromere. In other words, a chromatid is only half of a replicated chromosome. So, the statement that "One of two identical 'sister' parts of a copied chromosome is called a chromatid" is incorrect.

2. False.
We can evaluate this statement by reviewing the stages of mitosis. Anaphase is the stage during mitosis when the sister chromatids separate and move towards opposite ends of the cell. It is characterized by the pulling of the chromatids by the microtubules attached to the centromeres. The final phase of mitosis, where the nuclear envelope reforms around the separated chromatids (now individual chromosomes), is called telophase, not anaphase.

3. False.
To determine whether this statement is accurate, we must understand the sequence of events during the cell cycle. Prophase is the first phase of mitosis, and it is primarily focused on preparing the cell for division. During prophase, the chromosomes condense, the nuclear membrane starts to break down, and the spindle apparatus begins to form. However, division of the cytoplasm occurs during a later stage called cytokinesis, which takes place after the completion of mitosis. So, the statement that "Division of the cytoplasm takes place during prophase" is incorrect.

I hope you are not in highschool.

A chromatid is one of the two identical copies of DNA making up a duplicated chromosome, which are joined at their centromeres, for the process of cell division (mitosis or meiosis). They are called sister chromatids so long as they are joined by the centromeres. When they separate (during anaphase of mitosis and anaphase 2 of meiosis), the strands are called daughter chromosomes

Anaphase, from the ancient Greek ἀνά (up) and φάσις (stage), is the stage of mitosis or meiosis when chromosomes separate in an eukaryotic cell. Each chromatid moves to opposite poles of the cell, the opposite ends of the mitotic spindle, near the microtubule organizing centers. During this stage, anaphase lag could happen.
>>>
Cytokinesis, from the greek cyto- (cell) and kinesis (motion, movement), is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. It is the division of the cytoplasm. It usually initiates during the late stages of mitosis
