Term
Karotype
Definition
=photgraphic representation of the chromosome of a cell
Term
sister chromatids formed
Definition
S phase
Term
sister chromatids separate and head towards opposite poles of cell
Definition
Anaphase
Term
major difference between prokaryotes & eukaryotes?
Definition
eukaryotes have linear chromosomes while most prokaryotes contains single circular chromosome
Term
DNA in eukarayotes is located inside a membrane bound nucleus
Definition
-yes but it also contains cytoplasmic DNA in mitochondrial & chloroplast chromosomes
Term
Cellular division important for?
Definition
Growth of multicellular organism
reproduction of unicellular organism
Term
change in chromosomes between G1 & G2 phases of interphase?
Definition
Chromosomes in G2 contain 2 linear pieces of DNA while those in G1 only have 1
Term
chromosome begin to condense in which phase?
Definition
prophase
Term
2 structures with same amt of DNA
Definition
-unreplicated chromosome & chromatid
(replicated has 2 sisters)
Term
occurs during prophase
Definition
-condensation
-formation of mitotic spincle
-fragmentation of nuclear membrane
Term
characteristic of metaphase?
Definition
chromosomes align to middle of cell
Term
At end of mitosis, cell has divided into 2 daughters
Definition
False, mitosis is the process of sorting chromosomes.
Cell does not divide until cytokinesis occurs
Term
