BOW 2 mutations

Non-sense mutation: Three codons tell the cell to stop providing amino acids to the protein which supposely has been reached. when this happens the process is cut short and therefore it is an incompleted process. A disease caused by this is Cystic fibrosiss.

Sense Mutation: It changes a  stop in the codon into one that codes for an amino acid. The results of this event are in an elongated protein.

Deletion Mutation: when a type of  gene mutation  the deletion of nucleotide causes a certain shift in the reading of the codons in the mRNA.

Insertion Mutation: It results from the being of extra nucleotides in a chromosome.

Frameshift Mutation: is caused by the deletions or insertions of a number of nucleotides that is not  even by  a DNA sequence.

Point Mutation: It changes only asmall area or a nucleotide in a gene.

Translocation Muation:Its a mutation in which a large  piece of chromosome breaks off and attaches to another chromosome.
