Phases of Mitosis
During which phase of mitosis does the nuclear envelope dissolve?
Prophase
46
What is the first step of DNA replication?
Unzipping by DNA helicase
Which process involves reproductive cells?
Meiosis
What is happening during G1?
Growth and Function
During which phase of mitosis do the spindle fibers attach to the centromere and chromosomes are moved to the middle of the cell?
Metaphase
How many chromosomes are in the daughter cells of mitosis?
46
What holds DNA in place?
Hydrogen bonds
Which process ends with 2 daughter cells?
Mitosis
Which part of the cell cycle do cells spend MOST of their time in?
Interphase
What is formed around the new sets of DNA during Telophase?
Two new nuclei
How many chromosomes are present in each gamete?
23
Which enzyme is responsible for adding new nitrogen bases from a template strand?
DNA polymerase
Which type of cell division takes place in the body cells?
Mitosis
During which phase does DNA replication take place?
S phase
During which phase of mitosis are chromosomes being pulled apart?
Anaphase
How many chromosomes are present in each cell after meiosis I?
23 (counted by the centromere)
Why is DNA replication considered to be a semi-conservative process?
DNA separates into two template strands that can be used to make 2 DNA strands from one.
Which type of cell division uses processes like crossing over and independent assortment to shuffle genes before making gametes?
Meiosis
G2
What is the name of the process where the cell membrane pinches off to fully separate the two new cells?
Cytokinesis
How many chromosomes are present in the parent cells of mitosis?
46
What does DNA stand for?
Deoxyribonucleic Acid
Which type of cell division includes metaphase II?
Why might a cell want to go into G0?
Resting phase meaning it does not meet the requirements for division, or there are too few resources.
