What phase is this?
prophase
anaphase
metaphase
Metaphase II
What phase is this?
Telophase
Telophase II
anaphase
interphase
This part of the cell cycle is where the cell carries out normal cell function, DNA is replicated, and prepares for nuclear division
interphase
prophase
anaphase
telophase
What is one similarity and one difference between mitosis and meiosis?
both go through divisions, but only mitosis makes 4 cells
both have the same number of chromosomes, but differ in number of cycles
both cells contain DNA, but only mitosis has crossing over
both cells replicate the DNA, but meiosis has 1/2 the # of chromosomes as mitosis
What is the benefit of crossing over and what phase?
it makes the chromosomes all lined up and occurs in metaphase
it exchanges genetic information increasing variability. Occurs in prophase I
it keep the genetic information identical and occurs during cytokinesis
none of the following are true
Is this mitosis or meiosis?
mitosis
meiosis
neither
