___________ chromosomes, either X or Y, determine the sex of the organism.
Two X chromosomes, XX, will be ___________ and XY will be ______________.
All other chromosomes, except X & Y, are called ___________________.
Chromosomes from a cell may be arranged in pairs by size starting with the longest pair and ending with the
sex chromosomes to make a ___________________.
A human karyotype has 22 pairs of _________________ and 1 pair of ___________ chromosomes (23 total).
OBJECTIVE #2 The Cell Cycle
Identify when and for what purpose cells divide. Describe how the cell cycle is organized.
All cells are derived from ______________ cells (Cell Theory).
C___________ d___________ is the process by which cells produce new cells.
Cell division differs in prokaryotes (bacteria) and eukaryotes (protists, fungi, plants, & animals)
Prokaryotes perform one type of cell division: __________ fission, where genetic material is segregated equally
between two daughter cells.
Eukaryotes perform two types of cell division:
______________: in which the number of chromosomes in the daughter cells is the same as in the parent cell.
______________: in which the number of chromosomes in the daughter cells is half the number in the parent
cell.
The reasons for cell division are for: Cell _________________, ___________ and ________________ of
damaged cell parts, ___________________ of the species
Some tissues must be repaired often such as the lining of gut, white blood cells, skin cells with a short lifespan.
So cells in these tissues divide _________________.
Other tissue cells do not divide at all after birth (such as ________________).
Since the instructions for making cell parts are encoded in the DNA, each new cell must get a
__________________ set of the DNA molecules.
This requires that the DNA be ___________________ before cell division.
Cell division includes both ______________ (the division of the nucleus) and cytokinesis (the division of the
________________).
Cells go through a _________ ___________ during their life before they divide to form new cells
The cell cycle includes 2 main parts --- _________, and __________. _____________ is the longest part of a cell's life cycle and is called the ____________ ________ because the

Interphase consists of 3 parts --- ___, ____, and ______ phases
G1 occurs _______ a cell has undergone cell division
Cells mature & increase in size by making more __________ and _________ while carrying normal
metabolic activities in G1
S Phase follows G1 and the genetic material of the cell (DNA) is _________________.
G2 occurs _________ S Phase and the cell makes all the structures needed to _____________.
Prokaryotes such as bacteria do not have a __________.
Prokaryotes divide into two identical new cells by the process of ___________ ___________.
Binary fission is an ___________ method of reproduction
Eukaryotes have a ___________ and ___________organelles which must be copied exactly so the _______
new cells formed from division will be exactly alike
The original ____________ cell and the resulting two new daughter cells must have ___________
chromosomes

eukaryotes

Control is by special ___________________ produced by oncogenes
___________________ in control proteins can cause cancer
