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.
ty ty t y ty t y




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.

body part to

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

- 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.

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.

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.
