Mutations

[go to this section in the Guide]
Chapter Six: DNA, RNA, and Protein Synthesis


Question 1
 A mutation is defined as
   1.  a change in an organism's DNA
2.  the growth of an abnormal cell structure
3.  the changing of a cell from one type to another
4.  a way of changing mRNA to proteins
 

Question 2
 Which of the following illustrates a single point mutation on a segment of DNA which reads TACACGGTG?
   1.  TACACGTGTG
2.  TACACGCTG
3.  GTGGCACAT
4.  TTCACGGAG
 

Question 3
 A frame shift mutation has more serious consequences than a point mutation because a frame shift mutation
   1.  cannot ever be transcribed onto an mRNA molecule
2.  prevents uracil from being used in the mRNA molecule
3.  only affects a single codon
4.  causes all of the codons after it to be different
 

Question 4
 Which of the following illustrates a frame shift mutation on a segment of DNA which reads TACACGCTG?
   1.  TACACGTGTG
2.  TACACGCTG
3.  GTGGCACAT
4.  TTCACGGAG
