When a mutation occurs by elimination of one base in a DNA sequence,this mutation is called a ________.
A)deletion mutation
B)insertion mutation
C)substitution mutation
D)translocation mutation
E)viral mutation

Question

Quizplus · Accepted Answer

A deletion mutation occurs when one or more bases are eliminated from a DNA sequence, resulting in a loss of genetic information. An insertion mutation, on the other hand, occurs when one or more bases are added to a DNA sequence, while a substitution mutation occurs when one base is replaced with another. Translocation mutations involve the transfer of a section of DNA to a different location within the genome, while viral mutations occur when viruses undergo changes in their genetic material. Therefore, the best choice for a mutation that occurs by elimination of one base in a DNA sequence is a deletion mutation (Choice A).
