Chapter 1: DNA Structure and Function
c c c c c




MULTIPLE CHOICE c




1. In which body or cell area are most genes in humans located?
c c c c c c c c c c c


a. Nucleus
b. Mitochondrion
c. Cytoplasm
d. Plasma membrane c




ANS: A c c


Most genes are part of the DNA located in the nucleus of body cells. Only a few genes are
c c c c c c c c c c c c c c c c c c


located in a cell’s mitochondrion or mitochondria. There are no genes or DNA in either the
c c c c c c c c c c c c c c c c


cytoplasm or the plasma membranes of any cell.
c c c c c c c c




2. Which condition or statement exemplifies the concept of genomics rather than genetics?
c c c c c c c c c c c


a. The gene for insulin is located on chromosome 11 in all people.
c c c c c c c c c c c


b. Expression of any single gene is dependent on inheriting two alleles. c c c c c c c c c c


c. Sex-linked recessive disorders affect males more often than females. c c c c c c c c


d. One allele for each gene is inherited from the mother, and one is inherited from the
c c c c c c c c c c c c c c c


father. c




ANS: A c c


Genetics is the study of the general mechanisms of heredity and the variation of inherited
c c c c c c c c c c c c c c


ctraits. Genomics is the study of the function of all the nucleotide sequences present within
c c c c c c c c c c c c c c


cthe entire genome of a s p e c i e s , Wi nWcW
c c l u.d iTn B
gSgeMn.
esWiS
n DNA coding regions and DNA noncoding
c c c c c c c c c c


regions. Selections B, C, and D all refer to mechanisms of heredity. Only selection A refers
c c c c c c c c c c c c c c c


to the function of a specific nucleotide sequence.
c c c c c c c




3. What is the purpose of phosphorous in a DNA strand?
c c c c c c c c c


a. Linking the nucleotides into a strand c c c c c


b. Holding complementary strands together c c c


c. Ensuring that a purine is always paired with a pyrimidine c c c c c c c c c


d. Preventing the separation of double-stranded DNA into single-stranded DNA c c c c c c c c




ANS: A c c


Each nucleoside becomes a complete nucleotide when a phosphate group is attached. The
c c c c c c c c c c c c


phosphates have multiple binding sites, and each one can link to two nucleotides. These
c c c c c c c c c c c c c c


linkages allow the nucleotides to be connected when placed into the DNA strand. The
c c c c c c c c c c c c c c


nucleotides within each strand are held in position by the linked phosphate groups, which
c c c c c c c c c c c c c c


act like the string holding a strand of beads together, forming a necklace.
c c c c c c c c c c c c c




4. What is the term used to define alternative forms of a gene that may result in different
c c c c c c c c c c c c c c c c


expression of the trait coded for by that gene?
c c c c c c c c c


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
c c c c c c c c c c c c c c


how that gene is expressed. The alleles may be identical in their sequence but do not have to
c c c c c c c c c c c c c c c c c c


be. When a dominant allele is paired with a recessive allele, only the dominant allele is
c c c c c c c c c c c c c c c c


expressed, and the recessive allele is silent. When a dominant allele is paired with another
c c c c c c c c c c c c c c c


dominant allele, they are both expressed (usually equally). Recessive alleles are only
c c c c c c c c c c c c


expressed when they are homozygous. Bases are the essential part of a nucleotide, of which
c c c c c c c c c c c c c c c


there are many within any gene region. Centromeres are the pinched-in part of a
c c c c c c c c c c c c c c


chromosome between the p arms and the q arms. The term diploid refers to the normal
c c c c c c c c c c c c c c c c


number of chromosome pairs within a cell. It is an adjective, not a noun. Therefore, the
c c c c c c c c c c c c c c c c


plural diploids does not exist.
c c c c c




5. What percentage of bases in a stretch of double-stranded DNA that contains 30% guanine
c c c c c c c c c c c c c


(G) bases would be adenine (A)?
c c c c c


a. 70%
b. 60%
c. 30%
d. 20%
ANS: D c c


Because of complementary pairing, if 30% of the bases are guanine (G), which always pairs
c c c c c c c c c c c c c c


with cytosine C, these two bases account for 60% of the total bases in this stretch. The
c c c c c c c c c c c c c c c c c


remaining bases make up 40% of the total. This 40% is composed of equal percentages of
c c c c c c c c c c c c c c c c


thymine (T) and adenine (A).
c c c c c




6. What is the term used to describe the organized picture of the paired chromosomes within a
c c c c c c c c c c c c c c c


cell used to determine whether chromosome numbers, structures, and banding patterns are
c c c c c c c c c c c c


normal? WWW.TBSM.WS
a. Pedigree
b. Phenotype
c. Karyotype
d. Autotype
ANS: C c c


A karyotype is a picture of an organized arrangement of all of the chromosomes within one
c c c c c c c c c c c c c c c


cell during the metaphase section of mitosis. The chromosomes are paired and then arranged
c c c c c c c c c c c c c c


by number according to size and centromere position. The banding pattern of each pair is
c c c c c c c c c c c c c c c


analyzed to determine whether areas have been deleted, expanded, or translocated. A
c c c c c c c c c c c c


pedigree also is a picture, but it illustrates several generations of a family history.
c c c c c c c c c c c c c c


Phenotypes are observable traits. Autotype is not a genetic term. c c c c c c c c c




7. What would be the sequence of DNA that is complementary to a DNA section with the base
c c c c c c c c c c c c c c c c


sequence of GGTCAATCCTTAG?
c c c


a. GATTCCTAACTGG
b. TTGACCGAAGGCT
c. AACTGGCTTCCGA
d. CCAGTTAGGAATC
