What you’ll learn to do: Recognize the impact of DNA mutations A mutation is a permanent alteration in the DNA sequence that makes up a gene; that is, the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building b...

AFLP Markers,or Amplified Fragment Length Polymorphism, refers to polymorphic markers created through the amplification of restriction enzyme-digested DNA fragments. Differences arise due to single nucleotide mutations, insertions, deletions, and other mutations that lead to changes in restriction enzyme reco...
As the amount of sequence data has grown, it has been possible to consider hexamer frequencies (i.e. two adjacent codons), which seem to provide an even better signal than single codons. Human gene mutations have also been observed more frequently at certain dinucleotides than others [9]. ...
Likewise, the usage of sex appears to [End Page 622] be a mechanism to avoid the negative consequences of accumulating mutations and not of much philosophic import, at least in a biological framework. The philosophic debates often appear to be about the nature of conceptual entities, such as ...
Spontaneous mutations occur in the absence of exogenous causes and can be due to a variety of factors such as errors made by DNA polymerases during replication (or repair). Transposon mutagenesis, plasmids, gene transfer in gram‐negative bacteria and genetic exchange in gram﹑ositive bacteria are...

We are now ready to move to a new level of detail—mapping functional domains within viral proteins or defining cis elements to the nucleotide level. This level of detail will require mutagenesis on a new scale, with recombinant viruses containing mutations within a given locus perhaps numbering ...
