Chapter 1: DNA Structure and Function
MULTIPLE CHOICE
1. In which body or cell area are most genes in humans located?
a. Nucleus
b. Mitochondrion
c. Cytoplasm
d. Plasma membrane
ANS: A
Most genes are part of the DNA located in the nucleus of body cells. Only a few genes are
located in a cell’s mitochondrion or mitochondria. There are no genes or DNA in either the
cytoplasm or the plasma membranes of any cell.
2. Which condition or statement exemplifies the concept of genomics rather than genetics?
a. The gene for insulin is located on chromosome 11 in all people.
b. Expression of any single gene is dependent on inheriting two alleles.
Pa
c. Sex-linked recessive disorders affect males more often than females.
d. One allele for each gene is inherited from the mother, and one is inherited from the
father.
ANS: A
Genetics is the study of the general mechanisms of heredity and the variation of inherited
traits. Genomics is the study of the function of all the nucleotide sequences present within
ss
the entire genome of a species,WWW.TBSM.WS
including genes in DNA coding regions and DNA noncoding
regions. Selections B, C, and D all refer to mechanisms of heredity. Only selection A refers
to the function of a specific nucleotide sequence.
3. What is the purpose of phosphorous in a DNA strand?
a. Linking the nucleotides into a strand
vi
b. Holding complementary strands together
c. Ensuring that a purine is always paired with a pyrimidine
d. Preventing the separation of double-stranded DNA into single-stranded DNA
ANS: A
be
Each nucleoside becomes a complete nucleotide when a phosphate group is attached. The
phosphates have multiple binding sites, and each one can link to two nucleotides. These
linkages allow the nucleotides to be connected when placed into the DNA strand. The
nucleotides within each strand are held in position by the linked phosphate groups, which
act like the string holding a strand of beads together, forming a necklace.
s
4. What is the term used to define alternative forms of a gene that may result in different
expression of the trait coded for by that gene?
a. Alleles
b. Bases
c. Centromeres
d. Diploids
ANS: A

For each single gene, two alternative forms of that gene, known as alleles, together control
how that gene is expressed. The alleles may be identical in their sequence but do not have to
be. When a dominant allele is paired with a recessive allele, only the dominant allele is
expressed, and the recessive allele is silent. When a dominant allele is paired with another
dominant allele, they are both expressed (usually equally). Recessive alleles are only
expressed when they are homozygous. Bases are the essential part of a nucleotide, of which
there are many within any gene region. Centromeres are the pinched-in part of a
chromosome between the p arms and the q arms. The term diploid refers to the normal
number of chromosome pairs within a cell. It is an adjective, not a noun. Therefore, the
plural diploids does not exist.
5. What percentage of bases in a stretch of double-stranded DNA that contains 30% guanine
(G) bases would be adenine (A)?
a. 70%
b. 60%
c. 30%
d. 20%
ANS: D
Pa
Because of complementary pairing, if 30% of the bases are guanine (G), which always pairs
with cytosine C, these two bases account for 60% of the total bases in this stretch. The
remaining bases make up 40% of the total. This 40% is composed of equal percentages of
thymine (T) and adenine (A).
6. What is the term used to describe the organized picture of the paired chromosomes within a
cell used to determine whether chromosome numbers, structures, and banding patterns are
ss
normal? WWW.TBSM.WS
a. Pedigree
b. Phenotype
c. Karyotype
d. Autotype
vi
ANS: C
A karyotype is a picture of an organized arrangement of all of the chromosomes within one
cell during the metaphase section of mitosis. The chromosomes are paired and then arranged
by number according to size and centromere position. The banding pattern of each pair is
be
analyzed to determine whether areas have been deleted, expanded, or translocated. A
pedigree also is a picture, but it illustrates several generations of a family history.
Phenotypes are observable traits. Autotype is not a genetic term.
7. What would be the sequence of DNA that is complementary to a DNA section with the base
sequence of GGTCAATCCTTAG?
a. GATTCCTAACTGG
s
b. TTGACCGAAGGCT
c. AACTGGCTTCCGA
d. CCAGTTAGGAATC
ANS: D
