How do gene flow, genetic drift, and mutation affect evolution? Why do different mutations accumulate in two species once they diverge? A. They can no longer mate and swap the mutation. B. Natural selection favors mutations in one species over another. C. Convergent Evolution How are...
A new study published in eLife explores how naturally occurring mutations affect the biophysical properties of nucleocapsid proteins in SARS-CoV-2. The researchers focused on the nucleocapsid protein, which is responsible for packaging and protecting the viral genome. They found that most mu...
How do mutations affect polypeptide structures and their function?Explain how one type of mutation might affect the protein produced by a given gene in a bad, good, and neutral way. Explain the effect at each step of transcription and translation....
When genome-wide association studies emerged, scientists expected to find just a few mutations in known genes linked to a disease that would explain the difference between healthy and sick individuals. The truth, however, is much more complicated. “Sometimes, there are hundreds or thousands of mu...
Influenza virus can escape most antibodies with single mutations. However, rare antibodies broadly neutralize many viral strains. It is unclear how easily influenza virus might escape such antibodies if there was strong pressure to do so. Here, we map all single amino-acid mutations that increase ...

In this case, the dominant model58 predicts that separate male- and female- sterile mutations on the same chromosome cause the shift from hermaphroditism to dioecy through an intermediate phase of gynodioecy. Once these mutations have occurred and reached sufficient frequency in the population, ...
What is a mutation and what role do mutations play in evolution through natural selection? Does our knowledge of gene modification through epigenetics and the ability of genes to affect more than one trait require us to reconsider our concept o...
DNA mutations are when the identity of a nucleotide changes during the lifetime of an individual or during the creation of new DNA in advance of cell division. Typically, every time the cell divides, the DNA sequence is faithfully copied from the mother cell to ...
