[BOW 2-2] Mutations.

I think this is photoshopped...




SENSE: Sense mutations occur among the bases that code for amino acids. They could be beneficial for disastrous.


NON-SENSE: This mutation that changes a codon to a stop codon, which results in a shorter and typically nonfunctional protein.


DELETION: Deletion is the loss of genetic substances. Any number of nucleotides can be deleted. Deletion can cause a frame-shift.


INSERTION: This is the addition of one or more nucleotide base pairs into a DNA sequence. Insertions range from anywhere in size.


FRAME-SHIFT: When the number of nucleotides are not divisible by 3, a frame-shift is caused. This is typically caused by deletions and insertions.


POINT: A single base is substituted for another. This changes the meaning of a codon, leaving the rest of the gene untouched.


TRANS-LOCATION: When a part of a gene gets placed at a different spot than its designation, a trans-location mutation takes place. This doesn't only cause mutations, but can also cause diseases and cancer.
