Select all the statements about mutations that are TRUE: A. Only DNA,gan mutate D. Mutations may be lethal B. DNA mutations occur during anaphase E. Mutations may be neutral C. Mutations may increase an organism's fitness

## Step 1<br />The problem involves understanding the nature of mutations and their effects on organisms. Mutations are changes in the DNA sequence of an organism's genome. They can occur in any type of cell, not just DNA, so statement A is false.<br /><br />## Step 2<br />Mutations can occur at any stage of the cell cycle, not just during anaphase. Therefore, statement B is also false.<br /><br />## Step 3<br />Mutations can indeed be lethal, meaning they can cause the death of an organism. This is because they can disrupt essential genes or regulatory regions, leading to the death of the organism. Therefore, statement D is true.<br /><br />## Step 4<br />Mutations can also be neutral, meaning they do not have any noticeable effect on the organism. This is because they may occur in non-coding regions of the DNA or they may not affect the protein produced by the gene. Therefore, statement E is true.<br /><br />## Step 5<br />Finally, mutations can increase an organism's fitness. This is because they can introduce new traits that may be beneficial for the organism's survival and reproduction. Therefore, statement C is true.
