Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
It could occur after a forest fire or flood.
<h2>
Answer:</h2>
<h3>Interphase</h3>
<h2>
Explanation:</h2>
<h3>The cell cycle is the period of time from the beginning of one cell division to the beginning of the next. The longest stage of the cell cycle is called interphase. Interphase is the stage that occurs in between cell divisions. During interphase, the cell grows and develops and performs its functions.</h3>
Single Recognition Particle (SRP) RNA is necessary for the targeting of proteins to the prokaryotic plasma membrane or to the eukaryotic endoplasmic reticulum membrane. Its job is to bind to the signal peptide of the membrane or secretory proteins coming from the ribosome at which time it forms a ribosome-nascent chain (RNC)-SRP complex.
SRP plays an important role in understsnding bacterial physiology, emphasizing the importance of proper membrane protein biogenesis, and demonstrates the ability of time-resolved quantitative proteomic analysis to provide new biological insights.
