Select all the choices below that give a way that DNA can be repaired. Chromosomes can be recombined to remove mutations. DNA polymerase corrects errors during replication by proofreading. After replication, incorrectly paired bases can be excised and replaced. The cell can commit programmed cell death (apoptosis).
Adi S.
Mutations to DNA nucleotides can occur in which of the following ways? Mark all that apply. Some mutations are based on changes in the nucleotide structure, which can be either reversible or not reversible. Mutations can occur in the presence of external mutagens, including UV/tanning, smoking, and/or carcinogens in our food and water. Mutations can occur based on mistakes by ribosomes during translation. Mutations can occur based on mistakes by DNA Polymerase during DNA replication.
Mj A.
Mutagens can cause mutations by a. chemically altering DNA nucleotides. b. disrupting DNA replication. c. altering the genetic code of an organism. d. all of the above. e. a and b only.
