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



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




ANS: A www w



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

e located in a cell’s mitochondrion or mitochondria. There are no genes or DNA in either t

he cytoplasm or the plasma membranes of any cell.

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



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



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



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. w ww

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

a. Linking the nucleotides into a strand ww ww ww ww ww

ANS: A www w



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

e phosphates have multiple binding sites, and each one can link to two nucleotides. The

se linkages allow the nucleotides to be connected when placed into the DNA strand. Th

e nucleotides within each strand are held in position by the linked phosphate groups, wh

rent expression of the trait coded for by that gene?
