Cell Division Flashcards
What is cell continuity?
Cell continuity means that all cells develop from pre-existing cells
What are chromosomes?
Chromosomes are coiled threads of DNA (which forms genes) and protein that become visible in the nucleus at cell division
What is a gene?
A gene is a section of DNA that contains the instructions for the formation of a protein
What is a haploid cell?
A haploid cell has one set of chromosomes, i.e. it has only one of each type of chromosome in the nucleus
What is a diploid cell?
A diploid cell has two sets of chromosomes, i.e. it has two of each type of chromosome in the nucleus
What is a homologous pair?
A homologous pair is two chromosomes of similar size with the same sequence of genes
What is the cell cycle?
The cell cycle is the changes that take place in a cell during the period between one cell division and the next
What is interphase?
Interphase is the phase in the cell cycle when the cell is not dividing
What is mitosis?
Mitosis is a form of nuclear division in which one nucleus divides to form two nuclei, each containing the same number of chromosomes with identical gene
What is cancer?
Cancer is a group of disorders in which certain cells lose their ability to control both the rate of mitosis and the number of times mitosis takes place
What is meiosis?
Meiosis is a form of nuclear division in which the four daughter nuclei contain half the chromosome number of the parent nuclei
What is the centromere?
The centromere is the point at which the chromosomes are attached in a double-stranded chromosome
