Define a genetic mutation and state the types of genetic mutations?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).
What are the types of genetic mutations?
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
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
Can a frameshift mutation be a silnt mutation?
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
What is a point mutuation?
A point mutation is a type of genetic mutation that involves a change in a single nucleotide base pair in DNA. This can result in the substitution of one nucleotide for another, the insertion of an extra nucleotide, or the deletion of a nucleotide. Point mutations can lead to changes in the amino acid sequence of a protein, which can affect its structure and function.
What a is mutation?
A mutation is simply a change in your genes or DNA sequence. The types of mutations in Biology are: substitution, insertion, deletion, and frame-shift. Contrary to popular belief, mutations are often harmless.
What are 3 types of mutation?
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.
What is the name for a change in DNA?
The answer is Mutations! The 3 basic types of mutations are substitution, insertion, and deletion.
Is a change in the base sequence of a DNA molecule?
a kind of mutation called deletion or insertion

What mutations would be considered frameshift mutations?
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)

A nucleotide sequence changes from attcgg to atcgg what type of mutation occurred?
There are 3 types of mutations that are possible. Insertion Substitution Deletion If we use a bit of logic and knowledge to figure out what each action does, then we can find out the answer. Insertion will the Insert. Substitution will be Substitute. Deletion will be Delete. To insert would mean to put into. To substitute would mean to replace. To delete would mean to take away. Using that knowledge we can assume that the type of mutation that occurred is deletion.
What are the factors that can increase number of mutations?
A mutation is simply an accidental change in your genes or DNA sequence. The types of mutations in biology are:substitution, insertion,delection and frame-shift.
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
