Deletion occurs when a whole segment of a gene is lost.
Gene duplication is a type of mutation that can add genes to a chromosome. During gene duplication, a segment of DNA is copied and inserted into the chromosome, leading to an increase in the number of copies of a particular gene. This can result in gene families with multiple copies of a gene that may evolve new functions over time.
A deletion mutation can be dominant or recessive, depending on the specific gene affected and the consequences of the deletion on the protein encoded by that gene. In general, the impact of a deletion mutation on an individual's phenotype will determine whether it is dominant or recessive.
Gene editing or genetic modification, where specific changes were made to the gene sequence. This alteration resulted in the deletion of "efg" and the insertion of "lmnop" in the chromosome's gene sequence.
This is known as a chromosomal translocation, which can result in genetic material being exchanged between chromosomes. Translocations can lead to disruptions in gene expression and potential genetic disorders. Depending on the specific genes involved, translocations can have diverse effects on an individual's health.
The three types of mutations are substitution (where one base is replaced with another), insertion (where an extra base is added), and deletion (where a base is removed). These mutations can alter the DNA sequence and potentially change the resulting protein.
Deletion and inversion are two types of chromosomal mutations. Deletion involves the loss of a segment of DNA, which can result in the loss of genes and potentially lead to various genetic disorders. Inversion, on the other hand, occurs when a segment of DNA is reversed end to end within the chromosome, which can disrupt gene function but generally retains the same amount of genetic material. Both mutations can affect gene expression and contribute to evolutionary changes, but they do so in different ways.

Huntington's disease is caused by a genetic mutation, specifically an expansion of CAG repeats in the HTT gene on chromosome 4. This mutation leads to the production of an abnormal protein that causes neurodegeneration. It is not due to a deletion or addition of a whole gene or chromosome, but rather an alteration within a specific gene.

Deletion
Deletion: loss of a chromosomal segment. Duplication: repetition of a chromosomal segment. Inversion: reversal of a chromosomal segment. Translocation: movement of a chromosomal segment to a new location on a different chromosome.
In single crossover gene deletion strategy, a linear DNA fragment with homology to the target gene is introduced, leading to recombination and deletion of the gene. In double crossover strategy, two DNA fragments are introduced flanking the target gene, leading to recombination events resulting in gene deletion. Double crossover strategy is more precise and can avoid potential off-target effects compared to single crossover strategy.

A segment of DNA on a chromosome that controls the production of a protein is called a gene. Chromosome a cellular structure that contains DNA.
The three types of mutations are substitution (where one base is replaced with another), insertion (where an extra base is added), and deletion (where a base is removed). These mutations can alter the DNA sequence and potentially change the resulting protein.
