How are mutations prevented during DNA replications?

WebMutations can also be the result of the addition of a nucleotide, known as an insertion, or the removal of a base, also known as deletion. Sometimes a piece of DNA from one chromosome may be joined to another chromosome or to another region of the same chromosome; this is known as translocation. WebMutations can result from a number of events, including unequal crossing-over during meiosis (Figure 3). In addition, some areas of the genome simply seem to be more prone to mutation than others. WebThere are different types of genetic mutations that can occur in a cell. Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. Non-sense mutations create a stop codon, which can prevent the protein from being produced entirely, while missense mutations ... optimum website
