Cell Division-Mitosis and Meiosis: Part 1: Definitions of Meiosis and Mitosis Flashcards
What are the two types of cell division?
Mitosis and Meiosis.
What is Mitosis’ function?
It functions in growth and repair.
How many genetically identical daughter cells does Mitosis produce? What is its/their chromosome number?
It produces 2 genetically identical daughter cells with chromosome number identical to that of the parent cell.
In Mitosis, each daughter cell is haploid/diploid (n/2n) same as the parent cell.
Each daughter cell is diploid (2n) same as the parent cell.
What type of organisms does Meiosis occur in?
It only occurs in sexually reproducing organisms.
What does Meiosis produce? What is its/their chromosome number?
It produces gametes (sperm and ova) with half the chromosome number of the parent’s cell. Each resulting in Haploid (n).
What is a chromosome made of?
A chromosome consists of highly coiled and condensed strand of DNA.
How many chromatids does a replicated chromosome have?
A replicated chromosome consist of two sister chromatids, where one is the exact same copy of the other.
What is a centromere?
A centromere is a specialized region that holds the sister chromatids together.
What connects the centromere to the centrosome during cell division?
Spindle fibers.
