Cell Cycle Flashcards
(20 cards)
A clone plant has a diploid chromosome number 12 what is the diploid chromosome number of the plant so that was used to produce the clone plant
12
The fusion and gametes (sperm and eggs) is called
Fertilization
The process by which a cell divides into two identical daughter cells is called
Mitosis
Cycling are a family of closely related proteins that
Regulate the cell cycle
Cancer is a disorder in which some cells have lost the ability to control their
Growth rate
If an organisms diploid number is 12 it’s haploid number is
Six
Crossing over results in
Genetic recombination
What is the end product of meiosis
Four haploid cells
In which phase of me meiosis are homologous chromosomes aligned in the equator
Metaphase one
In anaphase one Homologus chromosomes separate. In Anaphase two what separates
Sister chromatids
What is the role of spindle during mitosis and meiosis
It helps separate the chromosomes
True or false prophase metaphase anaphase telaphase all represent the phases of mitosis in the proper sequence
True
What happens between meiosis one meiosis two that reduces the number of chromosomes
Replication does not occur
When during the cell cycle are chromosomes visible
Only during cell division
Two or false interphase is part of mitosis
False
True or false interphase consists growth during G1 And G 2 phases and synthesizes during S
True
The failure of chromosomes to separate properly during meiosis is called
Nondisjunction
If nondisjunction occurs during meiosis what will happen
The chromatids do not separate
What is nondisjunction
The failure of chromosome pairs or sister chromatids to separate
What are the different cell stages in the mitosis cell cycle
Prophase metaphase anaphase telophase
