This is called an Insertion.
the example of lethal dominant mutation is huntington's disease.
A good mutation is BACTERIAL FLAGELLA. A bad mutation is DOWN SINDRAM
An insertion mutation is when an extra nucleotide is inserted into the DNA molecule.For example if the original sequence is:AATGCATGGACTan insertion could be:AATCGCATGGACTThis would change the code from: AAT GCA TGG ACTto AAT CGC ATG GAC T.....You can see that after the insertion all the codes are changed. Since each set of three nucleotides codes for an amino acid, this would change all of the subsequent amino acids in the protein coded for by the gene.
A mutation that makes a rabbit able to run faster.
If the mutant codon still codes for the same amino acid (a silent mutation). For example: GUU, GUC, GUA and GUG all code for the amino acid Valine. So if the mutation changed the codon from GUU to GUA - Valine would still be produced and therefore the polypeptide will be identical.
Only one or two nucleotides are changed in a certain mutation. This is an example of a(n)
Deletion
The second types of point mutations are called insertions and deletions. Here, one or more nucleotides are added to or deleted from a gene. With insertions, several nucleotides that weren't there before are put into a sequence.
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
A Missense Mutation.It is a point mutation where the mutations alters the base sequence without changing the resulting function of the subsequent protein. This is usually when the mutation does not change the amino acid which the codon codes for.
Messenger RNA (mRNA) serves as the primary transcript, and its nucleotide sequence determines the amino acid sequence of proteins. A codon in mRNA comprises of three nucleotides that encode a specific amino acid. For example, the codon for glutamine is CAG (Cytosine, Adenine and Guanine). The most common stop and start codon is TAA and AUG respectively.
the example of lethal dominant mutation is huntington's disease.
A good mutation is BACTERIAL FLAGELLA. A bad mutation is DOWN SINDRAM
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)
