Insertions and deletions are called frame shift mutations because they alter the reading frame of the genetic code during protein synthesis. When nucleotides are added or removed in numbers that are not multiples of three, the triplet codons shift, leading to a completely different sequence of amino acids downstream from the mutation. This can result in nonfunctional proteins or significantly altered functions, as the original codon sequence is disrupted.

What are the types of mutations that can occur during transcription and translation?
During transcription and translation, mutations can primarily be classified into three types: point mutations, insertions, and deletions. Point mutations involve a change in a single nucleotide, which can lead to silent, missense, or nonsense mutations. Insertions and deletions involve the addition or loss of nucleotides, potentially causing frameshifts that alter the reading frame of the genetic code. These mutations can impact protein synthesis, leading to functional changes in the resulting proteins.
What do point mutations and frame shift mutations have in common?
Point mutations and frame shift mutations both involve changes in the DNA sequence of a gene. However, point mutations result from the substitution of a single nucleotide, while frame shift mutations occur from insertions or deletions of nucleotides, leading to a shift in the reading frame of the gene. Both types of mutations can have significant effects on the resulting protein sequence and function.
What are the types of gene mutations?
Deletion (resulting in a frame shift), duplication (also resulting in a frame shift), or a plain old SNP (change of base). You might also be looking for one which changes the amino acid coding sequence and one that does not.
How point mutation frame shift mutation and meiosis contribute to genetic variation?
Point mutations introduce single nucleotide changes in the DNA sequence, leading to variations in protein coding sequences. Frame shift mutations result from insertions or deletions of nucleotides, altering the reading frame and causing significant changes in protein sequences. Meiosis, through the processes of crossing over and independent assortment, shuffles genetic material between homologous chromosomes, generating new combinations of alleles and increasing genetic variation among offspring.
What change in a DNA sequence that affects genetic information?
A change in a DNA sequence that affects genetic information is called a mutation. Mutations can include substitutions (replacing one base with another), insertions (adding extra bases), deletions (removing bases), or frameshifts (shifting the reading frame). These changes can alter the instructions encoded in the DNA, potentially leading to differences in the proteins produced or causing genetic disorders.
Why are insertions and deletions called frameshift mutations?
Insertions and deletions are called frameshift mutations because they shift the reading frame of the genetic code during protein synthesis, leading to a change in the sequence of amino acids in the resulting protein. This can have significant effects on the structure and function of the protein.
Are deletions worse than insertions?
Deletions an insertions are equally harmful s they shift whole frame .

Was the sequence a result of point or frame shift mutation?
No
What are the Different types of Mutations?
a bunch of stuff acxtually 4 major mutations to look at these go to Google and type in your question. if this does not work for you then sucks for you
What are two types of frame shift mutations?
"I believe there is insertion and deletion, (one kind), and substitutions. (the second kind)" This answer is incorrect, the two types of frameshift mutation are insertion and deletion, these both alter the translation reading frame. A substitution point mutation in DNA is referred to as a single-nucleotide polymorphism and does not result in any change to the translational reading frame. insections and deletions are two types of frameshift mutations
What are the various kinds of mutations?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations

Which mutation is the most dangerous?
There is no definite answer to this question many types of mutations can cause death and I'd say that's the most dangerous effect of a mutation. Large Scale mutations, like deletions or amplifications, usually cause the most damage because they effect whole chromosomes. Small Scale mutations are usually less dangerous because they only effect one gene. The worst small scale mutations are insertions and deletions because they change the reading frame. In my personal opinion, harmful mutations that occur in the tumor suppressor genes are the most dangerous because they are what prevent the mutations in cell from being duplicated and without them working a mutated cell can replicate uncontrollably.
