The deletion or insertion of one nucleotide into the DNA sequence will result in a frameshift mutation which changes the reading frame that the tRNA follows when assembling amino acids from the DNA sequence. Each amino acid is coded for by a codon of three specific nucleotides. Shifting this frame can result in a different amino acid being added to the growing polypeptide chain. Also, a stop codon can be read and thus prematurely end the polypeptide chain. This creates incorrect and/or incomplete proteins. This could lead to serious problems if essential proteins are being saccrificed due to the mutation.
Frameshift mutations change the genetic material by adding or deleting nucleotides.

a frameshift mutation
Pablo Y Fer♥!! 4ever!
true
Referring to the frameshift mutation in genes, frameshift is where number of nucleotides inserted or deleted is not a multiple of three, resulting in every codon after the point of insertion or deletion is read incorrectly during translation.
1. Insertion- when a nucleotide gets added to the DNA strand2. Substitution- when a nucleotide gets replaced on the DNA strand3. Deletion- when a nucleotide gets deleted from the DNA strandThose are all of the DNA mutation types. Hoped this really helped you out
Here's a sample nucleotide sequence:AATUGCIf there was a nucleotide deletion (let's say the "G" gets deleted), the sequence would become:AATUCIf there was a nucleotide addition/insertion (let's say a "G" was added between "T' and "U"), the sequence would become:AATGUGCThe difference is that a deletion makes the DNA shorter and an insertion makes it longer.
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
When a base pair is added or deleted in a DNA sequence it's called an insertion or a deletion, which causes a frameshift mutation.
the deletion or addition results in a mutation
A change in the nucleotide sequence of DNA is called a mutation.Mutations take several forms:* substitution: one base is replaced by another* deletion: one or more nucleotides disappear from the sequence and the rest close up* insertion: one or more nucleotides appear between what had been adjacent nucleotides* duplication: a form of insertion in which a sequence of nucleotides is copied and now appears twice instead of once. Mutations can be caused by certain types of radiation, including ultraviolet (UV), and certain chemical compounds, which are therefore referred to as mutagenic.Mutations are particularly likely to occur at a point during replication of DNA when the two strands are separated.

errors in duplicating the DNA when splitting cells. there can be an insertion in the code, a deletion, and a change.
a kind of mutation called deletion or insertion
a kind of mutation called deletion or insertion
In mature mRNA, there is a start codon (AUG) that instructs ribosome to begin translation. Thereafter, every 3 bases are read as a "code word" calling for a particular amino acid to enlogate the polypeptide chain or to STOP and release the polypeptide. If 1 or 2 nucleotides are deleted or inserted into this sequence, it causes the reading frame to shift. This usually results in misreading of the sequence here is an example: AUG - AGC - ACC - TAA - GGG - etc. (if we delete the first C we get....) AUG - AGA - CCT - AAG - GG ( this is obviously not going to code for the same amino acid sequence)
The answer is Mutations! The 3 basic types of mutations are substitution, insertion, and deletion.
