What animal filled the role of top predator in yellowstone before wolves were reintroduced?
mixer [17]

Answer:

Explanation:

El Parque Nacional de Yellowstone (Estados Unidos), considerado el parque nacional más antiguo del mundo, fue creado en 1872 durante la presidencia de Ulysses S. Grant. En sus inicios, la fauna del parque no recibió la misma protección que hoy en día: los lobos y los pumas fueron eliminados deliberadamente en 1926 y, al cabo de unos años, la población de ciervos aumentó tanto que los administradores del parque reconocieron que los herbívoros estaban alterando la vegetación, por lo que se realizaron matanzas selectivas para controlar la población de dichos animales. Las matanzas selectivas terminaron a finales de los años 60 y la población de ciervos volvió a aumentar, por lo que finalmente se optó por reintroducir el lobo: 14 lobos de la provincia de Alberta (Canadá) fueron liberados en 1995 y otros 17 lobos canadienses en 1996. "La reintroducción del lobo (Canis lupus) en el Parque Nacional de Yellowstone es el experimento ecológico más celebrado de la historia", así comienza un estudio publicado en Journal of Mammalogy por Mark Boyce, de la Universidad de Alberta.

Which of the events would prevent a labelled nucleotide from being added to a growing dna strand if they occurred while dna poly
Pani-rosa [81]

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.
