sections of DNA are called _____

genes

nucleus

6

a cell that has lost its nucleus can no longer ______

divide

7

when the cell is not dividing, the genetic material is loosely dispersed throughout the nucleus in a threadlike form called _______

chromatin

8

when the cell is in the process of dividing to form daughter cells, the chromatin coils and condenses forming dense rode like bodies called _____

chromosomes

9

the nucleus also contains one or more small spherical bodies called ______

nucleoli

10

nucleoli composed primarily of _________ and ___________

proteins

RNA

11

the nucleus is bound by a double-layered porous membrane called the ________

nuclear envelope

12

the main structural building blocks of the plasma membrane are ______ and _______

phospholipids

globular protein moelcules

13

Tiny spherical bodies composed of RNA and protein; floating free or attached to a membranous structure (the rough ER) in the cytoplasm. Actual sites of protein synthesis.

ribosomes

14

Membranous system of tubules that extends throughout the cytoplasm; two varieties: rough and smooth. Rough ER is studded with ribosomes; tubules of the rough ER provide an area for storage and transport of the proteins made on the ribosomes to other cell areas.

endoplasmic reticulum

15

___________ which has no function in protein synthesis, is a site of steroid and lipid synthesis, lipid metabolism, and drug detoxification.

smooth endoplasmic reticulum

16

Stack of flattened sacs with bulbous ends and associated small vesicles; found close to the nucleus.

golgi apparatus

17

Plays a role in packaging proteins or other substances for export from the cell or incorporation into the plasma membrane and in packaging lysosomal enzymes.

golgi apparatus

18

Various-sized membranous sacs containing digestive enzymes including acid hydrolases; function to digest worn-out cell organelles and foreign substances that enter the cell. Have the capacity of total cell destruction if ruptured and are for this reason referred to as “suicide sacs.”

lysosomes

19

Small lysosome-like membranous sacs containing oxidase enzymes that detoxify alcohol, free radicals, and other harmful chemicals. They are particularly abundant in liver and kidney cells.

perioxosomes

20

Early Prophase

As the chromosomes appear, the _______ disappear, and the two centrosomes _______ from one another.

nucleoli

separate

21

Paired, cylindrical bodies that lie at right angles to each other, close to the nucleus.

centrioles

22

As part of the centrosome, these organelles direct the formation of the mitotic spindle during cell division; form the bases of cilia and flagella and in that role are called basal bodies.

centrioles

23

two stages of cell life cycle

interphase

cell division

24

the longer period during which the cell grows and carries out its usual activities

interphase

25

when the cell reproduces itself by dividing.

cell division

26

In an interphase cell about to divide, the genetic material (DNA) is copied exactly via __________.

DNA replication

27

_________ is the division of the copied DNA of the mother cell to two daughter nuclei.

mitosis

28

___________ is the division of the cytoplasm, which begins when mitosis is nearly complete.

cytokinesis

29

The product of ______ is two daughter nuclei that are genetically identical to the mother nucleus.

mitosis

30

a specialized type of nuclear division that occurs only in the reproductive organs (testes or ovaries)

meiosis

31

_______ which yields four daughter nuclei that differ genetically in composition from the mother nucleus, is used only for the production of gametes (eggs and sperm) for sexual reproduction.

meiosis

32

The function of cell division, including ________ and _________ in the body, is to increase the number of cells for growth and repair.

mitosis

cytokinesis

33

the phases of mitosis

prophase

metaphase

anaphase

telophase

34

Early Prophase

Late Prophase.

37

_____phase is not a part of mitosis.

Interphase

38

During Interphase, the DNA-containing material is in the form of _________. The _________ and one or more nucleoli are intact and visible.

chromatin

nuclear envelope

39

The three distinct periods of interphase:

G1

S phase

G2

40

The three distinct periods of interphase:

the centrioles begin replicating

(adding cytoplasm, cell getting bigger)

G1

41

The three distinct periods of interphase:

DNA is replicated

(growth and DNA synthesis)

S Phase

42

The three distinct periods of interphase:

Final preparations for mitosis are complicated, and centrioles finish replicating

(make copies of all needed organelles; lysosomes, golgi body, etc.)

G2

43

Early Prophase

The chromatin condenses, forming barlike _____________

chromosomes

44

Early Prophase

Each duplicated chromosomes consists of two identical threads, called ___________ held together at the ____________.

sister chromatids

centromere

45

Early Prophase

As the chromosomes appear, the _______ disappear, and the two centrosomes _______ from one another.

nucleoi

separate

46

Early Prophase

The centrosomes act as focal points for growth of a microtubule assembly called the _________-.

mitotic spindle

47

Late Prophase

The ___________ breaks up, allowing the spindle to interact with the chromosomes.

nuclear envelope

48

Late Prophase

Some of the growing spindle microtubules attach to _______, special protein structures at each chromosome's centromeres. These are called ______.

kinetochores

kinetochore microtubules
