A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.


"Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.

If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.

Here is an example of one sentence with words of only three letters: The big red pig ate the red rag. Each word will make one amino acid and the words make a sentence that makes sense.

Mutations that replaces one base for another will result in this: The beg red peg ate the red rag. This mutation can be read OK.

But another type might make the sentence totally readable: The big res dpi gat eth ere dra.

What are the differences between point mutation and frameshift mutation?

  A point mutation is where a single letter is the only thing changed in the DNA sequence. Lets say your phone number (or DNA code) was 483-1839 and you mistakely told som

Describe how point mutations and frameshit mutations affect the synthesis of proteins?

Point mutations will only affect a aingle amino acid in a protein chain, which could or could not affect the actual protein. If a point mutation occured and coded for a stop c

Which has the larger effect frameshift mutation or point mutation?

Point mutations are normally single base substitutions in a DNA strand. For example: Imagine this is a DNA strand split up into 3 bases. Instead of: The fat cat ate the we

How is frameshift mutation caused?

Frameshift mutations are caused by the insertion or deletion of a number of nucleotides that isn't evenly divisible by three from a DNA sequence.

2 Describe how point mutation and frameshift mutation affect the synthesis of proteins?

A point mutation is a change in a single base pair in DNA. A change in a single nitrogenous base can change the entire structure of a protein because a change in a single amin

How can a mutation affect protein synthesis?

If the mutation is in a coding region of a chromosome, then you may have one of several errors. The most likely would be a frameshift error or a substitution error. With a fra

Why does a frameshift mutation have more effect than a non-frameshift mutation?

This is because a frameshift mutation (caused by the insertion or deletion of bases) caused the entire coding strand to shift by one base. This means that all of the codons at
In Biology

Why does a frameshift mutaion usually cause more defects during protein synthesis than a point mutation?

A point mutation affects the identity of a single amino acid within a protein whereas a frameshift mutation can potentially affect the identity of many amino acids. Protein
In Biology

Why frameshift mutations have greater effect than point mutations?

The point mutation only changes the one amino acid coded for by the  triplet containing that mutation, but a frameshift mutation  produces an entirely new reading of all tri
