CELL DIVISION PT 1
Prior to cell division, a cell has 14 chromosomes. How many will each of the daughter cells have?
2
All species have
A number of chromosomes that is unique to that species
What is the roll of the DNA in a cell
DNA is where all the information is stored in a cell
Chromosome
DNA wrapped around chromosomes
Cytokinesis
Division of cytoplasm
Mitosis
Division of the Nucleus
What are the five stages of the cell cycle
G1, S, G2 mitosis cytosinesis
Centromeres
Hold together sister chromatids
Sister chromatids
Identical parts replicated in a chromosome
G1, S, and G2 are collectively known as?
Interphase
Which of the following is true of interphase?
It consists of the G1, S, and G2 phase. It composes a large part of the life cycle of a cell. It is a time of cell growth and development. a cell is preparing for division during this time
Mother cell
Original cell at beginning of division
S phase
Replication of DNA occurs
G2 phase
The cell assembles the special structures needed for cell division
G1 phase
The cell doubles in size, the enzymes, cytoplasmic organelles and other molecules double in number
What problems might arise in a cell that did not complete its G1 phase prior to cell division?
The new cell might not have all the necessary organelles
Daughter cell
The product of cell division
Which of the following is the most important in determining how quickly materials can move into and out of a cell?
The surface area of the cell
As the cell grows larger which would increase rapidly? volume or surface area?
The volume of the cell increases more rapidly
Which of the following would be true at the completion of cell division?
Two identical daughter cells will have been formed
Cell division
When the cell divides
DNA
carries genetic information
Interphase
is where the cell prepares for cell division
The DNA is copied during which one of the following?
the S phase
