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.
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 are changes in chromosome structure called?
A change in the number or structure of chromosomes is called
What are some example of inheritable change in DNA?
Inheritable change can be defined as any change in the DNA sequence. It can be a deletion of base, insertion, substitution duplication etc. A point mutation is normally enough to stop the expression of proteins or make it immature(if it happens at the right place).
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 is the name for a change in DNA?
The answer is Mutations! The 3 basic types of mutations are substitution, insertion, and deletion.
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)
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
What can cause mutations in the DNA structure?
errors in duplicating the DNA when splitting cells. there can be an insertion in the code, a deletion, and a change.

What is a change in the sequence of bases in DNA molecules called?
The change in the order of the bases in a DNA molecule is called a mutation. Such changes may happen because of damage to genomes, replication errors, or insertion or deletion of nucleotide bases.
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.

Do all mutations in DNA coding for mrna cause a change in an organism?
No. Some mutations can be silent, meaning that they have different codes yet it produces the same protein. If it is a mutation for the start of a mRNA sequence, then the polypeptide will just be discarded if there is no AUG.
