Answer:
small
Explanation:
The overall error rate of DNA polymerase during replication is 10-8 errors per base pair. Repair enzymes fix 99% of these lesions for an overall error rate of 10-10 per bp. That means one change occurs in every 10 billion base pairs that are replicated.
DNA replication is a highly accurate process, occurring rapidly and with a small number of mistakes, due to the efficiency of the DNA polymerase enzyme and the cell's repair mechanisms. However, any uncorrected mistakes can cause significant consequences, like mutations or even diseases like cancer. This process has been closely studied in prokaryotes such as E. coli.
DNA replication, a critical biological process, typically occurs with a remarkably small number of mistakes, thanks to the accuracy of the DNA polymerase enzyme and other repair mechanisms. This process has been particularly well-studied in prokayotes, like E.
coli, which can replicate its 4.6 million base pairs in about 42 minutes, adding around 1000 nucleotides per second.
However, when mistakes do occur and are not corrected, they can lead to mutations which might have serious consequences, such as cancer, particularly if the repair enzymes themselves are mutated or defective.

Eliminate
B) ecosystem
C) community
D) ecological niche
hello
The Answer is B) ecosystem
A(n) Ecosystem is a collection of all of the abiotic factors and biotic factors in an entire region.
b.paracrine
c.neuronal
d.contact-dependent?
Endocrine. Because insulin is a hormone that are produced in the endocrine gland such as pancreatic gland
The number of fire stations along the river was doubled.
b.
The public was restricted from accessing the Cuyahoga River.
c.
Public awareness of water pollution increased.
d.
Ohio residents organized a massive campaign to clean up the river.
The right answer is C
The Cuyahoga-river has been designated as one of the American Heritage Rivers. This river is also famous for having, in 1969, literally caught fire.
This combustion, related to the dumping of flammable and toxic products (fire-hazard products) in this river, it was a trigger in the ecological awareness in the United States (and also outside the USA).
a. All the proteins the cell creates from the miscopied strand will do different jobs than the old ones.
b. The miscopied DNA will be replaced with an accurate DNA copy once the cell divides.
c. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.
d. The cell that receives the miscopied DNA will die, and the cell with the accurate copy will live.
When a base is skipped during DNA replication, it can lead to a mutation and altered protein function.
When a base in one of the DNA strands is skipped during replication, it can lead to a mutation in the DNA sequence. This means that the resulting protein created from the miscopied DNA strand may have a different structure and function compared to the original protein. Therefore, option a. All the proteins the cell creates from the miscopied strand will do different jobs than the old ones, is the most likely result of this error.
