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.

1. Sedimentary-formed from particles of sand, shells, pebbles, and other fragments. Generally soft and breaks apart easily.
2. Metamorphic-formed under the surface of earth from the change from the heat and pressure. These rocks will have a shinny crystal like shine to them.
3. Igneous-formed when the magma cools down and hardens. Won't have a shinny look to it. Sometimes will have tiny holes in them.
Answer:
The algae can release harmful chemicals known as "bio-toxins" that can contaminate the water and kill the organisms living in the ecosystem
Explanation:
Answer:
3.2 piles
Explanation:
step 1
Find out the number of lumps in 10 clumps
we know that
3 lumps equals 1 clump
by proportion
Let
x ----> the number of lumps

step 2
Find out how many piles are 96 lumps
we know that
10 clumps equals 1 pile
10 clumps equals 30 lumps
so
1 pile equals 30 lumps
using proportion
Let
x -----> the number of piles
