chapter 10 Flashcards
DNA is copied
in the S phase of interphase
A gene
is a sequence of nitrogeneous bases in DNA
Sister Chromatids
contain identical DNA information
In mitosis, chromosomes line up at the cell mid plane during
Metaphase
Cell plate formation occurs
during cytokinesis
Cell division in bacteria is called
binary fission
In mitosis the nuclear membrane begins to breakdown during
Prophase
Meiosis produces
haploid cells
each homolog of a pair of homologous chromosomes
carries the same genes but potentially different alleles than its pair
Crossing over occurs during
prophase 1
Homologs separate during
anaphase 1
Genetic variation during sexual reproduction occurs during
crossover and independent assortment
Prokaryotic chromosomes are
circular
During Mitosis the # of chromosomes
stay the same from beginning to end.
During Meiosis the # of chromosomes
cut in half from beginning to end
