What effect can a replication error have on the traits of an organism?
A
It has no effect on the organism's traits.
B
It always results in the death of the organism.
C
It only affects the organism's behavior, not its physical traits.
D
It can lead to a beneficial mutation that enhances survival.
Verified step by step guidance1
Understand that replication errors occur during DNA replication when the DNA polymerase makes a mistake in copying the DNA sequence.
Recognize that these errors can lead to mutations, which are changes in the DNA sequence. Mutations can be neutral, harmful, or beneficial.
Consider that a beneficial mutation might enhance an organism's survival by improving a trait, such as resistance to a disease or better adaptation to environmental conditions.
Acknowledge that not all replication errors result in beneficial mutations; some may have no effect or could be harmful, potentially leading to diseases or disorders.
Conclude that the effect of a replication error on an organism's traits depends on the nature of the mutation and how it influences the organism's phenotype.
