Which of the following happens when a cell divides? Question 32 options: a. The cell's volume increases. b. It becomes more diff
icult for the cell to get enough oxygen and nutrients. c. The cell has DNA overload. d. Each daughter cell receives its own copy of the parent cell's DNA.
Cell division is a process whereby a cell splits into two (mitosis) or more (meiosis) identical (mitosis) or non-identical (meiosis) daughter cells. Cells undergo division to increase in number/multiply or reproduce.
Before a cell can divide; whether through meiosis or mitosis, its genetic material (DNA) must first be replicated. This process of DNA replication occurs in the S-phase of interphase (resting stage before division). DNA replication involves synthesizing a copy of the original DNA making two copies, which will then be shared into the arising daughter cells.
The DNA gets duplicated prior to division by the cell, this is done in order to ensure that each daughter cell receives the a correct number of genetic material from the parents. The duplicated chromosome (DNA) splits into two, each going to opposite cells, in the anaphase stage of either meiosis or mitosis, after which cytokinesis (division of cytoplasm) occurs with each cell possessing a copy of chromosomal material.
The term the nurse should use to report and describe the
findings in the patient is known as “Melena”. Melena is known to be the dark
sticky feces containing a part of digested blood. Melena can be produced by
swallowing blood or it may indicate that a person is bleeding internally.
