The nurse is answering nursing students' questions about the process of meiosis and mitosis. Which statement by a student should the nurse correct?
A) "In mitosis, cells divide to form an identical cell."
B) "Gonadal cells contain 23 chromosomes."
C) "Sperm and egg cells are diploid cells."
D) "Haploid cells have 23 chromosomes."
C) "Sperm and egg cells are diploid cells."
Explanation: A) The process of cell division used to create identical copies of a cell is called mitosis.
B) Gonadal cells, that is egg and sperm cells, have only half of the genetic information (one of each chromosome pair), or 23 chromosomes total.
C) In meiosis, egg and sperm cells are created for reproduction. Meiosis begins with a cell that has 46 total chromosomes, two of each chromosome type. However, the goal is to place one of every chromosome pair into a cell. This occurs by following DNA replication with two sets of cell divisions, and the end product is four daughter cells, each with a total of 23 chromosomes, one of each chromosome pair. These are called haploid cells.
