While the DNA in a human skin cell was being replicated, a single base was miscopied. What will be the most likely result of thi
s for the cell in which it happened? (2 points) All the proteins the cell creates from the miscopied strand will do different jobs than the old ones.
Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.
If the new sequence codes for the same amino acid as the original cell, it will function normally.
<u>Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.</u>
Explanation:
Once the cell enter cell division, there are checkpoint to repair damaged or mismatched DNA. Checkpoint activation pauses the cell cycle to provide the cell enough time to repair the damage before continuing to divide. DNA damage checkpoints occur at the G1/S and G2/M boundaries. The DNA polymerase will correct a mismatch or miscopied base on the strand before continuing with replication.Through this, the enzyme prevents mutations that would likely happen.
When air pollution began, it caused acid rain, damaging and destroying forests. It caused animals to become ill and potentially die as the acid rain ruined their environment. The air pollution also made around 400,000 people die faster than they would without air pollution.
