If a human skin cell with 46 chromosomes divided by mitosis, how many chromosomes will each daughter cell have?

  • A) 23
  • B) 12
  • C) 46
  • D) 92

Correct Answer: C) 46

Explanation

In order to understand this question, let's first discuss what mitosis is. Mitosis is the process of cell division in which a parent cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. This is how our bodies grow and repair themselves. The human skin cell mentioned in the question has 46 chromosomes. During mitosis, these chromosomes are duplicated, and then separated into two new cells. As a result, each daughter cell will also have 46 chromosomes, which is the same number as the parent cell. Therefore, the correct answer is Option C: 46. It is important to note that mitosis is different from meiosis, another type of cell division that occurs in reproductive cells. In meiosis, a parent cell divides into four non-identical daughter cells, each with half the number of chromosomes as the parent cell. This is how our bodies produce sperm and egg cells for reproduction.
