Proofreading of newly-synthesized DNA is important because .A) DNA pol III has a high error rate during replicationB) The cell will invariably die if any mutations occur during replicationC) A high fidelity in the copying of DNA is necessary for good heredityD) Any protein made from mutated DNA will not function properly

D) Any protein made from mutated DNA will not function properly

Explanation: During replication, DNA polymerase double-checks and removes every newly added wrong nucleotide. This is to maintain high fidelity because if a mutated DNA is synthesized during replication, it will also lead to synthesis of an RNA with an altered nucleotide sequence during transcription and consequently lead to the synthesis of a protein that will not function well during translation.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
