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.

Answer:
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Explanation:
The amazing process begins with the female digging a hole in the gravel with her tail. A female salmon will lay a few thousand eggs in the hole that will be fertilized by the male fish. Eventually the new baby salmon hatch out of these eggs.
Answer:
Fungi like protist feed on decaying leaves.
They reproduce by using spores.
They use pseudopods to engulf any foreign material and convert it into food.
Explanation:
Fungi like protist are Majorly molds and they are common seen on decaying organic matter and they normally absorb nutrients while feeding.
They are much similar to fungi and reproduce through spores even as fungi reproduce. They can be found in soils, lawns, trees and they do not have major cell wall divisions.
The use their pseudopods to engulf foreign material and convert it to food which supply them with nutrients.
Examples are slime molds and water molds.
Answer:
I do not agree with this statement.
Explanation:
Plants and some bacterias are autotrophic, meaning that they manufacture their own food from basic elements using an energy source in an anabolic process. Plants mostly utilize sunlight which they trap with the help of their green pigmentation called chlorophyll. Bacteria on the other hand mostly get their energy source by splitting chemical compounds, utilizing the liberated bond energy of the compound (examples is the sulfur bacteria) to fuel their food building process.
