-
In preparation for cell
division, DNA is
replicated and the
chromosomes
condense
-
Haploid, nuclious contains single set of chromosomes, diployes 2
-
SEXUAL REPRODUCTION
fusion of two GAMETES
-
-
HAPLOID NUCLEUS
-
MEIOSIS
number of chromosomes is halved, they are different from each other
cell
division, d.n.a is
replicated and the
chromosomes
condense
Cell not close to cell division: chromosomes are uncoiled or uncondensed
(Chromatin, a complex of d.n.a. plus structural proteins )
