1) How does DNA structure relate to its function?
ty t y ty t y t y ty t y
- The order of nucleotides in a DNA strand specifies the order
t y t y t y t y t y t y t y t y t y t y
of amino acids in aprotein.
t y t y ty t y ty
2) What is a difference between the structure of DNA and proteins?
t y t y t y t y t y t y t y ty ty t y
- DNA is composed of nucleotides and proteins are composed of amino
ty t y t y ty t y t y ty t y t y ty
acids. ty
3) A genome can be best described as
ty t y t y t y t y t y
- the DNA in all chromosomes in a cell.
t y ty t y ty t y t y t y
4) What is the difference between the function of DNA and the function of
t y t y t y t y ty t y t y ty ty t y t y t y
proteins? ty
- DNA stores genetic information and proteins perform most cellular functions.
ty t y t y ty t y ty ty t y t y
5) Which statement supports the theory that all organisms are related?
ty t y t y t y ty t y ty ty t y
- The genetic code is almost universal.

6) New genes are thought to arise by which mechanism?
t y t y t y t y t y t y ty t y
- Gene duplication followed by divergence due to mutation.

another?
- The mutated gene encodes a protein that affects the expression of many
t y t y t y t y t y ty t y t y t y ty ty
tyother
genes.
8) A recent technical advancement that has accelerated the study of
t y t y t y t y t y t y t y t y t y
genomes is the abilityto
t y ty t y ty
- sequence large complex genomes rapidly and inexpensively.

9) What is the difference between genetic dissection and genome sequencing?
ty ty t y ty ty ty ty ty t y
- Genetic dissection reveals information about one gene at
t y t y t y t y t y t y t y
a time and genomesequencing reveals information about all the
t y t y ty t y t y t y t y t y ty
genes in a genome at once.
t y t y t y ty t y t y
10) Currently, what information can be obtained from sequencing an individual's
ty ty ty ty ty t y ty ty ty
genome?
t y
- Information about gene variants that predispose a person to a
t y t y t y t y t y t y t y t y t y
t y disease, such asIcm ancer.

11) Which is not a potential problem of allowing the genomic
t y t y t y t y t y t y t y t y t y
sequences of individuals tobecome widely available?
t y t y ty ty t y t y

12) One strand of DNA has the sequence
t y t y t y t y t y t y t y 5′ t y GGTCTA t y 3′. t y What
is the sequence of the otherstrand?
t y t y t y t y ty t y
- 5′ TAGACC 3′ ty ty
13) Which statement t y t y is true about the structure of DNA?
t y t y t y t y t y ty
- The two strands of a DNA molecule are held together by base pairing.
t y t y t y ty t y ty t y t y t y t y ty t y
14) The size of the mouse (M. musculus) genome is 2700 megabases (Mb) and it
ty ty ty ty ty ty ty ty ty ty ty t y t y
contains
t y about 25,000 genes arranged
t on
y 40 chromosomes. If t y t y t y t y t y t y t y
tthe genes are evenly distributed on chromosomes in the mouse, what
y t y t y ty t y t y t y t y t y t y t y
is the average number of genes per chromosome?
t y t y t y t y t y ty t y t y
- 625 ty
15) Which statement about the structure of proteins is false?
ty t y t y t y t y t y t y t y
- Most proteins consist of two amino acid polymers attached
t y t y t y ty ty t y t y t y
together by hydrogen bonding.
t y ty ty ty
16) Which is a structural feature shared by DNA, RNA, and proteins?
t y t y t y ty t y t y ty t y t y t y
- The order of monomers is important for function.
t y t y ty t y t y t y ty
17) A segment of a protein has the amino acid sequence Ser—Gly—Leu.
t y t y t y t y t y t y t y t y t y t y
Is it possible toinfer the sequence of the RNA that encodes this
t y t y ty t y t y t y t y ty t y t y t y t y
amino acid sequence?
t y t y t y
No; more than one type of RNA (more than one base
t y t y t y t y t y t y t y t y t y t y
sequence) could encode this aminoacid sequence.
