Which of the following statements about mutations is FALSE?
Which of the following statements about mutations is FALSE?
Tap to reveal answer
A mutation is a genetic variation that happens by chance. A mutation is not necessarily good or bad. Some mutations are harmful, and end up causing the organism to die sooner than its counterparts. Some mutations have no effect on an organism at all. Other mutations that are inheritable and beneficial, have the potential to become standard in a population. Through the process of natural selection, more individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits. This is ultimately how evolution occurs.

This is ultimately how evolution occurs.
Some types of mutations:
Deletion: When a segment of DNA is lost, so there is a missing segment in the chromosome. These usually result in many genes missing from the chromosome.
Duplication: When a segment of DNA is repeated, creating a longer chromosome. These usually result in multiple copies of genes in the chromosome.
Inversion: When a segment of DNA is flipped and then reattached to the same chromosome.
Insertion: When a segment of DNA from one chromosome is added to another, unrelated chromosome.
Translocation: When two segments from different chromosomes change positions.

Translocation: When two segments from different chromosomes change positions.
The answer is "the insertion of a nucleotide into DNA."
A mutation is a genetic variation that happens by chance. A mutation is not necessarily good or bad. Some mutations are harmful, and end up causing the organism to die sooner than its counterparts. Some mutations have no effect on an organism at all. Other mutations that are inheritable and beneficial, have the potential to become standard in a population. Through the process of natural selection, more individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits. This is ultimately how evolution occurs.
Some types of mutations:
Deletion: When a segment of DNA is lost, so there is a missing segment in the chromosome. These usually result in many genes missing from the chromosome.
Duplication: When a segment of DNA is repeated, creating a longer chromosome. These usually result in multiple copies of genes in the chromosome.
Inversion: When a segment of DNA is flipped and then reattached to the same chromosome.
Insertion: When a segment of DNA from one chromosome is added to another, unrelated chromosome.
Translocation: When two segments from different chromosomes change positions.
