Unit 4: Cell Reproduction, Mitosis, DNA, and Protein Synthesis, Flashcards
Active Immunity
A form of acquired immunity in which the body produces its own antibodies against a pathogen; long-term protection
Adult Stem Cells
stem cells that are found in adults that can differentiate to form a limited number of body cells
AIDS
(acquired immunodeficiency syndrome) a disease caused by HIV (human immunodeficiency virus) which attacks and kills T cells in the immune system
Antibiotic
a drug used to fight and kill bacterial infections; Ex. penicillin
Antibody
a Y-shaped protein that attaches to foreign molecules and signals their destruction by white blood cells
Anticodon
three letters (nitrogen bases) on a tRNA molecule
Asexual Reproduction
A reproductive process that involves only one parent and produces offspring that are identical to the parent.
Antiviral
new class of drugs used to treat viral infections; Ex. tamiflu
B-Cell
a type of white blood cell that makes antibodies
Cancer
Uncontrolled cell division
Cell Cycle
life cycle of a cell that consists of interphase, mitosis, and cytokinesis
Chromatin
tangled up spaghetti like DNA mixed with protein; only found during interphase
Chromosomes
formed when DNA coils tightly around proteins
Complementary Base Pairing
A always pairs with T and G with C in DNA; in RNA, A always pairs with U and G with C
Cholera
A disease spread by bacteria in contaminated water that causes an infection in the intestine and results in severe vomiting and diarrhea; can be fatal
Cytokinesis
last step of the cell cycle in which the cytoplasm divides into two cells
Daughter Cells
the cells that result from the division of a single parent cell; produced in mitosis and meiosis
