The purine or pyrimidine base was removed from the labeled nucleotide base.
A DNA polymerase enzyme recognizes this and replaces the is inserted nucleotide allowing replication to continue. Calibration corrects approximately 99% of these types of errors but is still not sufficient for normal cellular function. Topoisomerases act in the region before the replication fork and prevent supercoiling.
Primase synthesizes RNA primers complementary to the DNA strand. Cells have various mechanisms to prevent mutations and permanent changes in DNA sequences. During DNA synthesis, most DNA polymerases check their work by repairing most mismatched bases in a process called proofreading. Errors can occur during the process of DNA replication. Nucleotide bases can be is inserted, deleted, or mismatched in a DNA strand.

The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
The fossil that I believe are heterotrophs cannot produce their food which includes all animals, fungi, and most bacteria and protists. These fossils are A, C, and fossil D.
