The Cell Cycle
Name the three stages of the cell cycle.
Interphase, Mitosis, Cyotkinesis
Which organ system is responsible for defending the body against infections?
The Immune System
Which organelle is the control centre of the cell?
Nucleus
What are the four types of tissue?
Connective, Epithelial, Nervous, Muscle
Describe the process of DNA screening.
A lab procedure that scans an individual's DNA for genes associated with genetic diseases.
In which phase of mitosis do the paired sister chromatids move to and line up at the centre of the cell?
Metaphase
What kind of blood passes through the left atrium of the heart?
Oxygenated
Which organelle receives proteins and materials from the endoplasmic reticulum and packages and distributes these materials?
Golgi Bodies
Define cell specialization.
The process by which cells develop into cells that have specific functions.
What are the four building block molecules of DNA? Describe how these molecules pair.
A, T, C, G
A pairs with T, C pairs with G
Describe one action the cell carries out during interphase.
Cell Growth, DNA Replication, carrying out activities of what the cell is designed to do, carrying out normal activities all cells perform
Which organ system is responsible for producing offspring?
The Reproductive System
Name one organelle that is found in a plant cell but not in an animal cell.
Cell Wall, Plastid, Chloroplast
Differentiate adult stem cells from embryonic stem cells.
Embryonic stem cells can give rise to any cell type. Adult stem cells are more specialized and can generate different cell types for a specific tissue or organ.
Provide two examples of transgenic organisms.
1) Bacteria that produce insulin
2) Pest Resistant Crops
Describe the main event that occurs in anaphase.
Spindle fibres retract, separating sister chromatids and pulling chromatids to opposite poles of the cell
Which organ of the respiratory system contains your vocal cords?
Larynx
Which organelle assembles amino acids to create proteins?
Ribosomes
Provide one advantage of using embryonic stem cells and one disadvantage of using embryonic stem cells.
Advantage - restorative medicine
Disadvantage - taken from human embryos
What is the function of a gene?
Genes control protein production.
In which phase of the cell cycle do centrioles double?
Interphase
Describe how the circulatory system is connected to the digestive system.
Name one organelle that is found in an animal cell but not in a plant cell.
Lysosome
Cells are specialized according to the _________ they contain.
Proteins
Describe the relationship between DNA, genes, and chromosomes.
DNA is a large molecule that contains hundreds or thousands of genes. DNA is organized into chromosomes in complex organisms.
