How do cells correct errors in dna that would disrupt their function? enzymes use the surrounding sections of the dna to determine the correct structure; then they repair the errors by replacing atoms in the existing molecule-
enzymes cut out the erroneous part and then use the complementary dna on the intact strand to add the correct
enzymes use rna that was made before the damage occurred to make a new double strand of dna to insert into the
the erroneous part has weaker bonds to the dna molecule, so it falls off, and the proper nucleotides are attracted to the gap to repair the damage.

Option). enzymes cut out the erroneous part and then use the complementary DNA on the intact strand to add the correct nucleotides

Explanation:

DNA errors can be defined as errors that take place occasionally during DNA replication, when the DNA polymerase adds a wrong base to the growing daughter strand.

Many enzymes, such DNA polymerase and ligase are involved to repair these errors. The repairing enzymes first cleaves the mismatched or incorrect base as it has exonuclease activity. Then,DNA polymerase adds the correct base by using information from complementary DNA on intact strand and DNA ligase seals the gap.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
