STUDY GUIDE WITH COMPLETE SOLUTION//
4 Phases of cell cycle




Answers:G1, S, G2, M
G1 Phase


Answers:Growth and normal metabolic roles
S phase


Answers:DNA replication


Chromosomes duplicate making sister chromatids
G2


Answers:Growth and preparation for mitosis
M Phase


Answers:mitotic phase

,(Prophase, Metaphase, Anaphase, Telophase)
Gametes


Answers:End product of meiosis
Somatic cells


Answers:body cells reproduced by mitosis
Difference between Diploid & Haploid


Answers:diploid: cell with two sets of chromosomes (one from each parent
haploid: a cell containing one set of chromosomes
Sister Chromatids


Answers:identical copies of a chromosome; full sets of these are created during the
S subphase of interphase
Homologous chromosomes


Answers:two chromosomes with the same length carrying gene for the same
characteristics (eye or hair color)
Difference between gametes and somatic cells


Answers:gametes are male and female sex cells that are the end product of meiosis


somatic cells are cells that keep making more of the same cells end product of
mitosis
What happens in Meiosis I?

, Answers:Homologous chromosomes condense and line up in center


Homologous chromosomes separate but sister chromatids do not separate (crossing
over)


Daughter cells move to Prophase 2
What happens in Meiosis II?


Answers:Meiosis II is like mitosis;


sister chromatids separate and four haploid cells are formed. Note that each has
half the chromosomes of the parent cell. These cells differ genetically from each
other and from the cells of the parents.
Purpose of Mitosis


Answers:to make more cells
Purpose of Meosis


Answers:produce gametes
Mitosis: Prophase


Answers:chromosomes condense and migrate towards opposite sides of the cell


movement caused by spindle fibers
Mitosis: Metaphase
