If the DNA polymerase did nothing special when a mispairing occurred between an incoming deoxyribonucleoside triphosphate and the DNA template, the wrong nucleotide would often be incorporated into the new DNA chain, producing frequent mutations. The high fidelity of DNA replication, however, depends not only on complementary base-pairing but also on several “proofreading” mechanisms that act sequentially to correct any initial mispairing that might have occurred.
Answer:
Kidney stones consist of buildup in the kidneys as a result of deposited minerals and salts that are present in urine. They can build up in the urinary tracts, and over time this can create kidney stones.
Answer:
Un organismo unicelular es aquel que está constituido por una sola célula en contraposición con los organismos pluricelulares constituidos por varias células. ... La mayoría de organismos unicelulares son procariotas, como las bacterias, pero existen algunos organismos unicelulares eucariotas, como los protozoos.
Explanation:
Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
