Questions and Answers

1.

Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells of humans. This extra chromosome occurs in a gamete as a result of
- A.
  
  An error in the process of cloning
- B.
  
  An error in meiotic cell division
- C.
  
  A gene mutation
- D.
  
  Replication of a single chromosome during mitosis
2.

Which statement best describes the relationship between cells, DNA, and proteins?
- A.
  
  DNA is composed of proteins that carry coded information for how cells function.
- B.
  
  Cells contain DNA that controls the production of proteins.
- C.
  
  Proteins are used to produce cells that link amino acids together into DNA.
- D.
  
  Cells are linked together by proteins to make different kinds of DNA molecules.
3.

Research has shown that certain body cells, known as stem cells, can develop into a variety of specialized cells. Various factors can cause stem cells to develop into different types of mature cells. These different types of mature cells result from
- A.
  
  Different antibodies and mitotic cell division
- B.
  
  Identical genetic codes and meiotic cell division
- C.
  
  Different environments of the cells and the functioning of different parts of the genetic code
- D.
  
  Similar steps in the development of the cells and a reduction in the number of chromosomes in each cell
4.

Which statement is true of both mitosis and meiosis?
- A.
  
  Both are involved in asexual reproduction.
- B.
  
  Both occur only in reproductive cells.
- C.
  
  The number of chromosomes is reduced by half.
- D.
  
  DNA replication occurs before the division of the nucleus.
5.

A cell resulting from the fertilization of an egg begins to divide. Two cells are formed that normally remain attached and could develop into a new individual. If the two cells become separated, which statement describes what would most likely occur?
- A.
  
  The cells would each have all of the needed genetic information, and both could survive.
- B.
  
  The cells would each have only one-half of the needed genetic information, so both would die.
- C.
  
  One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.
- D.
  
  One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.
6.

Although all of the cells of a human develop from one fertilized egg, the human is born with many different types of cells. Which statement best explains this observation?
- A.
  
  All cells have different genetic material.
- B.
  
  Mutations occur during development as a result of environmental conditions.
- C.
  
  Developing cells may express different parts of their identical genetic instructions.
- D.
  
  Some cells develop before other cells.
7.

Tissues develop from a zygote as a direct result of the processes of
- A.
  
  Fertilization and meiosis
- B.
  
  Fertilization and differentiation
- C.
  
  Mitosis and meiosis
- D.
  
  Mitosis and differentiation
8.

Some cells involved in the process of reproduction are represented in the diagram below. The process of meiosis formed

- B.
  
  Cells 1 and 2
- C.
  
  Cell 3, only
- D.
  
  Cells 2 and 3
9.

Which statement concerning the reproductive cells in the diagram below is correct?
- A.
  
  The cells are produced by mitosis and contain all the genetic information of the father.
- B.
  
  If one of these cells fertilizes an egg, the offspring will be identical to the father.
- C.
  
  Each of these cells contains only half the genetic information necessary for the formation of an offspring.
- D.
  
  An egg fertilized by one of these cells will develop into a female with the same characteristics as the mother.

- B.
  
  Differentiation and growth
- C.
  
  Antibodies and antigens inherited from the father
- D.
  
  Meiosis and fertilization
11.
