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.
Gene deletion: The total loss or absence of a gene. Gene deletion plays a role in birth defects and in the development of cancer.ene deletion: The total loss or absence of a gene. Gene deletion plays a role in birth defects and in the development of cancer.
