A nucleotide can be misplaced in a DNA strand during replication. How are misplacements in DNA nucleotide strands corrected so that the final error rate is low?
by supercoing to inactivate the gene region in which a misplaced nucleotide has occurred
by the chemical action of special enzymes that can detect and replace misplaced nucleotides
by lysosomes that move along the strands removing any strands of nucleotides containing misplaced nucleotides
by the complementary DNA strand removing the misplaced nucleotides and connecting the open ends of the strand together

the answer for this question would be d. glaciers

explanation: bc blah

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
