Chapter 8 Flashcards: Chromosomes and cell division

Hint fission split into parts (nuclear fission occurs when the nucleus of an atom splits into smaller parts) [definition]
Hint the process of cell division in prokaryotes binary fission
Hint the structure that holds the two sister chromatids of a chromosome together centromere
Hint the fusion of haploid gametes to create the diploid zygote, or fertilized egg fertilization
Hint the division of the cytoplasm during the cell cycle cytokinesis
Hint checkpoints during this cycle regulate cell division and mitosis cell cycle
Hint an uncontrolled growth of cells that may become malignant to become cancer tumor
Hint pro forward/before (prolog) [prefix]
Hint meta after, in the midst of, change (metamorphosis is a state of change) [prefix]
Hint ana back (anal, anus) [prefix]
Hint telo end, far, tail (Greek telos; telephone means calling over a distance) [prefix]
Hint DNA condenses into visible chromosomes during this stage of mitosis prophase
Hint a network of protein fibers formed from microtubule subunits during prophase of mitosis spindle
Hint stage of meiosis where homologous chromosomes pair up and crossing over occurs prophase I
Hint stage of meiosis where homologous chromosomes separate anaphase I
Hint stage of meiosis where sister chromatids separate anaphase II
Hint disjunct distinct, separation [definition]
Hint unequal distribution of chromosomes during meiosis results in incorrect number of chromosomes in gametes nondisjunction
Hint nondisjunction resulting in the existence of three copies of chromosome 21 and Down syndrome trisomy 21
