A gene mutation occurs in a group of animals. As a result, they show a different pattern of behavior. Which of the following could be the behavior change? A. A group of bats start to be active during the day instead of at night. B. A herd of cows start to moo in a different ...
In animal evolution, gene mutations may affect the growth rate of animals. Which animal shows a possible effect of gene mutation on growth rate? A. A puppy that grows into a large dog much faster than usual. B. A kitten that changes its sleeping position frequently. C. A chick that ...
the printout, from being used to build proteins. Another way to disable the function of a gene is to "knock-out" the gene in the DNA itself, by creating change, or a mutation in the DNA. In our analogy this would be to change, or even delete, the folder containing...
Mutations can occur at the level of entire chromosomes or parts of chromosomes, or at the level of the individual gene.Gene mutationcan originate either from an error inDNA replication(spontaneous mutation) or a failure to repair DNA damage (induced mutation). During DNA replication, errors occur...

Culture (behaviour based on socially transmitted information) is present in diverse animal species, yet how it interacts with genetic evolution remains largely unexplored. Here, we review the evidence for gene–culture coevolution in animals, especially
The researchers also report that a drug affecting a specific type of nerve function reduced the obsessive behavior in the animals, suggesting a potential way to treat repetitive behaviors in humans. The findings appear in the Feb. 24 issue of theJournal of Neuroscience. ...
Role of mutation in the gyrA and parC genes of nalidixic-acid-resistant salmonella serotypes isolated from animals in the United Kingdom. V, McLaren I and Griggs DJ, Role of mutations in the gyrA and parC gene of 196 nalidixic acidresistant Salmonella serotypes isolated from animals. J... ...
Gene trapping relies on the random insertion in the genome of generic trapping cassettes; when this type of insertional mutation occurs in introns, a fusion transcript results, encoding a truncated and nonfunctional version of the cellular protein and a reporter/selectable marker; the cassette ...
Mutationsoccur when the number or order of bases in a gene is disrupted. Nucleotides can be deleted, doubled, rearranged, or replaced, each alteration having a particular effect. Mutation generally has little or no effect, but, when it does alter an organism, the change may be lethal or ca...
