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.
How can gene mutations affect health and development? To function correctly, each cell depends on thousands of proteins to do their jobs in the right places at the right times. Sometimes, gene mutations prevent one or more of these proteins from working properly. By changing a geneâs instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely.
