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.
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
the entire genome of a s p e c i e s , Wi nWcW
l u.d iTn B
gSgeMn.
esWiS
n 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
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
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.
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
