,5) The immediate product of transcription is .
A) a phospholipid
B) an amino acid
C) a protein
D) a carbohydrate
E) RNA
Answer: E

6) In many species, there are two representatives of each chromosome. In such species, the
characteristic number of chromosomes is called the number. It is usually symbolized
as .
A) haploid; n
B) haploid; 2n
C) diploid; 2n
D) diploid; n
E) None of the answers listed is correct.
Answer: C
Section: 1.2
7) Genetics is the study of .
A) heredity and variation
B) mutation and recession

D) diploid and haploid
E) replication and recombination
Answer: A
Section: 1.2
8) Early in the twentieth century, Walter Sutton and Theodore Boveri noted that the behavior of
chromosomes during meiosis is identical to the behavior of genes during gamete formation. They
proposed that genes are carried on chromosomes, which led to the basis of the .
Answer: Chromosome Theory of Inheritance
Section: 1.2
9) What is a mutation?
Answer: A mutation is an inherited change in a gene.
Section: 1.2
10) What is a simple definition of an allele?
Answer: An allele is a variant form of a gene.

, 11) Until the mid-1940s, many scientists considered proteins to be the likely candidates for the
genetic material. Why?
Answer: Proteins are the most abundant, universally distributed components in cells. Because
of their great structural and functional diversity, they were considered likely candidates.
Section: 1.2
12) Name the individual who, while working with the garden pea in the mid-1850s,
demonstrated quantitative patterns of heredity and developed a theory involving the behavior of
hereditary factors.
Answer: Gregor Mendel
Section: 1.2
13) What does the term genetics mean?
Answer: Genetics is a subdiscipline of biology concerned with the study of heredity and
variation at the molecular, cellular, developmental, organismal, and populational levels.
Section: 1.2
14) Name the substance that serves as the hereditary material in eukaryotes and prokaryotes.
Answer: DNA or deoxyribonucleic acid
Section: 1.2
15) Name two individuals who provided the conceptual basis for our present understanding that
genes are on chromosomes.
Answer: Walter Sutton and Theodore Boveri
Section: 1.2
16) What term is used to describe the fact that different genes in an organism often provide
differences in observable features?
Answer: phenotype
Section: 1.2
17) A fundamental property of DNA's nitrogenous bases that is necessary for the
double-stranded nature of its structure is .
Answer: complementarity
Section: 1.3
18) Recombinant DNA technology is dependent on a particular class of enzymes, known as
, that cut DNA at specific nucleotide sequences.
Answer: restriction enzymes
Section: 1.4
19) Name the botanist who, in 1900, rediscovered the work of Gregor Mendel.
Answer: Carl Correns
