A) In what phase of mitosis do chromosomes split into sister chromatids? (1 point)
cytokinesis
anaphase
prophase
telophase
The correct answer is anaphase.
A) Which type of stem cell is able to differentiate into any cell type, including extraembryonic
placental cells? (1 point)
embryonic cells
multipotent cells
totipotent cells
pluripotent cells
The correct answer is totipotent cells.
A) Which correctly describes sister chromatids? (1 point)
They form during metaphase when DNA is being replicated.
They are part of the lined-up chromosomes in mitosis.
They are the daughter cells that form during cell replication.
They make up the mitotic spindle within the cell.
The correct answer is: They are part of the lined-up chromosomes in mitosis.
The correct answer is B) anaphase.
To determine the correct answer, we need to have a basic understanding of mitosis and its different phases. Mitosis is the process of cell division in which one cell divides into two identical daughter cells. It consists of several main stages: prophase, prometaphase, metaphase, anaphase, and telophase.
In anaphase, the pairs of sister chromatids separate and move to opposite poles of the cell. This splitting of sister chromatids into two separate chromosomes is a crucial step in ensuring that each daughter cell receives a complete set of chromosomes.
To recap, during anaphase of mitosis, chromosomes split into sister chromatids, allowing for proper distribution of genetic material to the daughter cells.
