A cell can divide into two or more cells through a process called cell division. A cell may divide by mitosis or by meiosis depends on the type of cell being formed.
This quiz will teach you the terms related to cell division as well as its processes and functions.
-
Question of
The thread-like structure where the DNA molecule is found.
-
Chromosome
-
Diploid
-
Microtubule
-
Chromatid
Correct Wrong
In animal and plant cells, chromosomes are thread-like structures located inside the nucleus. Chromosomes consist of protein and a single molecule of deoxyribonucleic acid (DNA). Each living creature has its own DNA, which is passed from parents to offspring.
-
-
Question of
Is a molecule similar to DNA. But unlike DNA, it is single-stranded.
-
Ribonucleic acid (RNA)
-
Prophase
-
Chromosome
-
Cytoskeleton
Correct Wrong
The polymeric molecule known as ribonucleic acid (RNA) plays various biological roles including coding, decoding, regulating, and expressing genes. The RNA and DNA are both nucleic acids.
-
-
Question of
An early mitotic cellular structure consisting of microtubules and a centrosome.
-
Asters
-
Gene
-
Gamete
-
Anaphase
Correct Wrong
A star-shaped cellular structure consists of a centrosome and microtubules which are associated with the early stages of mitosis in animal cells. The asters allow the cells to divide properly, resulting in each daughter cell having full copies of its chromosomes.
-
-
Question of
A stage of mitosis where the chromosomes line up at the center of the cell.
-
Metaphase
-
Anaphase
-
Interphase
-
Telophase
Correct Wrong
During metaphase, chromosomes are at their second-most condensed and coiled state (anaphase is when they are most condensed).
-
-
Question of
Refers to a cell that has only a single set of chromosomes.
-
Haploid
-
Metaphase
-
Centromere
-
Asters
Correct Wrong
A haploid cell or organism has only one set of chromosomes. Asexual organisms are haploid. Organisms capable of sexual reproduction are diploid (having two sets of chromosomes, one from each parent). Humans possess only haploid cells in their egg and sperm.
-
-
Question of
Is the basic physical and functional unit of heredity.
-
Gene
-
Chromosome
-
Meiosis
-
Asters
Correct Wrong
Heredity is made up of physical and functional units called genes. The genes are organized one after another on structures called chromosomes. Chromosomes contain a single, long DNA molecule, of which only a portion corresponds to a gene. A human's chromosomes contain around 20,000 genes.
-
-
Question of
The division of all of your body’s cells except sex cells.
-
Mitosis
-
Meiosis
-
Chromatin
-
Deoxyribonucleic Acid
Correct Wrong
Mitosis is the process of replicating chromosomes and producing two identical nuclei in preparation for cell division. Mitosis is followed by the equal division of the cell nuclei and other contents into two daughter cells.
-
-
Question of
A eukaryotic cell’s final stage of meiosis and mitosis.
-
Telophase
-
Interphase
-
Cytokinesis
-
Gamete
Correct Wrong
At telophase, nucleoli and nuclear membranes disintegrate, reversing the effects of prophase and prometaphase.
-
-
Question of
The end of a chromosome.
-
Telomere
-
Chromatid
-
Daughter cell
-
Homologs
Correct Wrong
Telomeres are the ends of chromosomes. The telomeres are repetitive sequences of non-coding DNA that protect chromosomes from damage. Telomeres shorten during cell division. As a result, cells become unable to divide as their telomeres shorten.
-
-
Question of
A cell which possesses paired chromosomes, one from each parent.
-
Diploid
-
Haploid
-
Asters
-
DNA replication
Correct Wrong
The term diploid refers to an organism or cell that possesses paired chromosomes from each parent. Except for human sex cells, all cells in humans are diploid and contain 23 pairs of chromosomes. Haploid cells (eggs and sperm) are sex cells that contain a single set of chromosomes.
