Frameshift mutations are genetic mutations that occur when nucleotides are inserted or deleted in a DNA sequence, causing a disruption in the normal "reading frame" during translation. This can lead to a significant change in the amino acid sequence of the resulting protein, affecting its structure and function.
Impact on Proteins
Frameshift mutations typically have a more severe impact on proteins compared to other types of mutations, such as point mutations. Because the reading frame is shifted, all subsequent codons are altered, often resulting in a non-functional or dysfunctional protein being produced.
Causes
Frameshift mutations can be caused by a variety of factors, including errors during DNA replication, exposure to mutagenic chemicals or radiation, or even the insertion of foreign DNA fragments. These mutations can occur spontaneously or be inherited from parents.
Effects
The effects of frameshift mutations can vary depending on the specific location and size of the insertion or deletion. In some cases, the mutation may lead to a premature stop codon, resulting in a truncated protein. In other instances, it may alter the entire protein's structure, leading to loss of function or gain of a new function.
Frameshift mutations are generally considered more disruptive than other types of mutations due to their significant impact on protein synthesis. They can result in various genetic disorders and diseases, including certain types of cancer and genetic disorders.
Research on frameshift mutations is essential for understanding the molecular basis of genetic diseases and developing potential treatments. Scientists use techniques such as gene editing tools and bioinformatics to study the effects of frameshift mutations and develop strategies to correct or mitigate their impact.
