A mutation is the change in the sequence of a nucleotide or in the organization of the DNA (genotype) of a living being, which produces a variation in the characteristics of this and that is not necessarily transmitted to the offspring. It occurs spontaneously and suddenly or by the action of mutagens. This change will be present in a small proportion of the population (variant) or of the organism (mutation). The genetic unit capable of mutating is the gene, the unit of hereditary information that is part of DNA.
In multicellular beings, mutations can only be inherited when they affect the reproductive cells. A consequence of mutations can be, for example, a genetic disease. However, although in the short term they may seem harmful, mutations are essential for our long-term existence. Without mutation there would be no change, and without change life could not evolve.
The definition of mutation from the knowledge that the hereditary material is DNA and the proposal of the double helix to explain the structure of the hereditary material (Watson and Crick, 1953), would be that a mutation is any change in the sequence of nucleotides of DNA. When this mutation affects a single gene, it is called a gene mutation. When it is the structure of one or more chromosomes that is affected, chromosomal mutation. And when one or several mutations cause alterations in the whole genome they are called genomic mutations.

Answer:
encoding
Explanation:
Encoding failure: In psychology, the term encoding failure is referred to as the brain's occasional or rare failure to create or form a memory. Whereas the term encoding refers to the brain's capability to store and recall an event's memory of short-term and long-term whenever needed. Encoding failure can occur due to various reasons, for instance, substance abuse, trauma, etc. The term is also referred to as pseudo forgetting as this is one of the theories of forgetting.
In the question above, Sarah's failure to provide the license plate number is most likely due to the encoding failure.
Answer:
LTP is produced in this preparation by delivering a burst of 100 electrical pulses in a few seconds via the stimulating electrode.
Explanation:
In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. It can be recorded in many parts of the nervous system, but is very widely studied in the hippocampus.
