Reviewing Main Ideas
1
Cell Division and Mitosis

• The life cycle of a cell has two partsgrowth and
  development, and cell division.

• In mitosis, the nucleus divides to form two
  identical nuclei. Mitosis occurs in four
  continuous steps, or phasesprophase, metaphase,
  anaphase, and telophase.

55
Reviewing Main Ideas
1
Cell Division and Mitosis

• Cell division in animal cells and plant cells is
  similar, but plant cells do not have centrioles
  and animal cells do not form cell walls.

• Organisms use cell division to grow, to replace
  cells, and for asexual reproduction. Asexual
  reproduction produces organisms with DNA
  identical to the parents DNA. Fission, budding,
  and regeneration can be used for asexual
  reproduction.

56

Sexual Reproduction and Meiosis

• Sexual reproduction results when an egg and sperm
  join. This event is called fertilization, and
  the cell that forms is called the zygote.

• Meiosis occurs in the reproductive organs,
  producing four haploid sex cells.

• During meiosis, two divisions of the nucleus
  occur.

• Meiosis ensures that offspring produced by
  fertilization have the same number of chromosomes
  as their parents.

57

DNA

• DNA is a large molecule made up of two twisted
  strands of sugar-phosphate molecules and nitrogen
  bases.

• All cells contain DNA. The section of DNA on a
  chromosome that directs the making of a specific
  protein is a gene.

58

DNA

• DNA can copy itself and is the pattern from which
  RNA is made. Messenger RNA, ribosomal RNA, and
  transfer RNA are used to make proteins.

• Permanent changes in DNA are called mutations.

Question 3
What type of nitrogen is found in RNA, but not in
DNA.
Answer
The answer is uracil. RNA has the base uracil
instead of thymine.

Question 4
When cells have pairs of similar chromosomes,
they are said to be _______.
Answer
The answer is diploid. A typical human body cell
is diploid.

Question 5
This illustration represents what division of the
nucleus?
LE 4.4
66
Chapter Review
Answer
The answer is meiosis 1. The end result of
meiosis 1 is a pair of new cells, each with one
duplicated chromosome from each parent.

Question 2
Which letter corresponds with telophase?
A. A B. B C. C D. D
LE 4.4
71
Standardized Test Practice
Answer
The answer is D. During telophase, spindle
fibers start to disappear, the chromosomes start
to uncoil, and a new nucleus forms.

Question 5
Which is the best answer?
A. The instructions for making a specific gene
are found in protein. B. Genes are found in the
cytoplasm. C. The gene determines the order of
amino acids in a protein. D. A change in the
gene does not change the outcome of an inherited
trait.
LE 2.1a
77
Standardized Test Practice
Answer
The answer is C. Changing the order of the amino
acids makes a different protein.
