This chip let the brightness of the Afterburner be controlled using the Game Boy Advance's existing buttons, so there was no need to carve an extra hole in the case to mount a dimmer. Due to the construction of the Game Boy Advance case, the Afterburner light is slightly too narrow to illuminate the screen evenly. This creates what is called the trapezoid effect: a trapezoid-shaped pattern of light across the screen.
Insertion or deletion of a single letter can sometimes cause a frameshift mutation, in which the entire amino acid sequence of the resulting protein is changed. Gene or Region Duplication. Sometimes errors during DNA replication can duplicate an entire gene or region of a genome. This type of error can cause more of a protein to be produced, because after duplication, there are two genes that encode it rather than one.
1 Silent Mutation: Although a change in the DNA sequence occurs, this type of mutation does not change the protein that is to be produced. 2  This is because multiple genetic codons can encode for the same amino acid. 3  Amino acids are coded for by three nucleotide sets called codons.uring protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease.
