depends. for example, it could have no effect/be helpful or it could be fatal if it leads to a malformation or lack of production of an important protein.
If the deletion occurs in a section where the DNA encodes for a protein, it will cause what is called a "frame shift". Each amino acid is encoded by a DNA codon which is made up of 3 nucleotides. By deleting a nucleotide (base) the codons are no longer read properly. As such, the subsequent protein is now made with the wrong amino acids. If this protein is critical to cell survival it can lead to cell death. There are also regions of DNA that control protein expression which if mutated by a base deletion will cause misregulation of protein expression. Fortunately however, a large percentage of DNA actually does not appear to code for anything. As such, a deletion in this part of the DNA tends not to have any affect at all.
A DNA base deletion can cause a frameshift mutation, where the reading frame of the genetic code is shifted. This can result in incorrect amino acids being added during protein synthesis, leading to a non-functional or altered protein. The impact on the organism depends on where the deletion occurs in the genome and the specific gene affected.
The deletion of a single nitrogen base in a particular gene will cause the rest of the genetic code for that particular gene to become senseless, and the protein that is supposed to be formed from that code will be useless. If this occurs in a gamete, then the resulting offspring can inherit a genetic disorder, or may not even be able to survive very long after fertilization. If this happens in a body cell, a tumor, including a cancerous tumor could result.

How many amino acids are affected by a deletion of one nitrogen base?
A deletion of one nitrogen base would result in a frameshift mutation in the DNA sequence that codes for proteins. This would likely affect all amino acids downstream of the deletion site, leading to a significant alteration in the protein's primary sequence and possibly its function.
What type of mutation occurred in the strand of DNA?
A point mutation occurred in the DNA strand. This is a change in a single nucleotide base, such as a substitution, insertion, or deletion.
What type of mutation when a nucleotide is dropped from a DNA sequence?
A deletion mutation occurs when a nucleotide is dropped from a DNA sequence. This can cause a shift in the reading frame, leading to a non-functional protein being produced.
What happens in deletion mutation?
In deletion mutation, a part of the DNA sequence is lost or removed, leading to a change in the genetic code. This can result in a frameshift mutation, where the reading frame is shifted, often leading to a nonfunctional protein being produced. Deletion mutations can have varying effects depending on the size and location of the deletion in the DNA sequence.
What type of mutation will the deletion of a DNA nucleotide from a strand of DNA cause?
The deletion of a DNA nucleotide from a DNA strand will cause a frameshift mutation, where the reading frame of the genetic code is shifted. This can lead to significant changes in the resulting protein sequence and function.
How does temperature affect the structure of the DNA?
The only effect know to affect DNA is mutation. mutation occurs as a result of the deletion or change is the codon of a base sequence, they can occur either in keto form or the enol form.And there are different mutagent capable of altering the base sequence of a DNA,the transition , transversion and frame shift. And this causes a change in the morphology of a particular organism.-prince david adedeji
A involves the addition or deletion of a single base in a DNA molecule.?
A Frameshift mutation
Is a change in the base sequence of a DNA molecule?
a kind of mutation called deletion or insertion
What is a change in the base sequence of DNA molecule?
a kind of mutation called deletion or insertion
Does a mutation in a gene affect the order of DNA bases?
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.

A point mutation occurred in the DNA strand. This is a change in a single nucleotide base, such as a substitution, insertion, or deletion.
How does DNA affect an orginsims traits?
DNA carries the genetic information that determines an organism's traits. The sequence of nucleotides in DNA determines the sequence of amino acids in proteins, which are essential for an organism's structure and function. Mutations in DNA can result in changes to an organism's traits.
What type of mutation when a nucleotide is dropped from a DNA sequence?
A deletion mutation occurs when a nucleotide is dropped from a DNA sequence. This can cause a shift in the reading frame, leading to a non-functional protein being produced.
