When a extra base is added to an organism DNA the mutation is known as a?
frameshift mutation.
Would protein be the same if a new base was inserted into the strand of DNA?
No. At the point of insertion the sequence would be completely changed. This is called a frameshift mutation.
What are changes in the bases of DNA?
When a base pair is added or deleted in a DNA sequence it's called an insertion or a deletion, which causes a frameshift mutation.
What is the difference between a nonsense mutation and a frame shift 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 someone that your phone number was 483-1835. that one digit is enough to make that person dial the wrong number (or cause a mutation in DNA.) For example suppose your DNA sequence was ACT GCT, a point mutation would just be a change in one of those bases (or letters), so it could end up something like : ACT ACT.EX: GTA CTG CAA-----> (point mutation) -----> GTA GTG CAAA frameshift mutation is generally much more serious and will cause a change all the way down a DNA sequence, making each codon (or every group of three bases) a different sequence, not just in one point or base like a point mutation, that would only slightly change the sequence of a single codon. A frameshift mutation happens not when a DNA base is simply changed, but when a whole base is added or deleted from the sequence of DNA. For example lets suppose your DNA sequence is GTA CCT AGG. In a frameshift mutation a whole base would be added somewhere in that sequence, making it look something like this: GTAT CCT AGG. Since it is impossible though to have 4 bases in a codon, your body would automatically shift every letter down one, even to the next codon in the sequence, to make room for this new base. In the end the final product would look something like this: GTA TCC TAG (with the left over G being the first base in the next codon, and so on).EX: CAG TTC CTG GAA -----> (frameshift muation) -----> CAG TTA CCT GGAAs you can see the frameshift mutation would leave the mutated DNA vastly more different from its parent DNA (that it was replicated from), then a point mutation would, though in both cases the DNA would still be different/mutated. This is because the codons would be more considerbaly changed with the frameshift (where now the sequence in every codon in different), rather than in a point mutation (where only one of the codons would be different).Hope this helps all you HS Bio 1 people like myself out there, or anyone else studying this subject.-- K.J.S
A change in which part of a gene is the result of a mutation?
Base Sequence
What type of mutation when a nucleotide is dropped from a DNA sequence?
Base-Pair insertions or deletions
During DNA replication an extra cytosine base is added to the DNA what type of mutation is this?
A frameshift mutation
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
How would a protein be changed if a mutation caused a base to be added?
A mutation in which an extra nitrogen base is added is called a frameshift mutation. The rest of the sequence after the mutation will code for different amino acids, which will result in the alteration of the protein. Frameshift mutations cause severe genetic disorders.
During DNA replication an extra cytosine base is added to the DNA What type of Mutation is this-?
Frameshift mutation
What mutation can change every amino acid that follows the point of mutation?
Frameshift mutations MAY change every amino acid that follows the point of mutation.
When a extra base is added to an organism DNA the mutation is known as a?
frameshift mutation.
Would protein be the same if a new base was inserted into the strand of DNA?
No. At the point of insertion the sequence would be completely changed. This is called a frameshift mutation.
What type of mutation is this during DNA replication a thymine base is removed from the DNA?
A frameshift mutation
A mutation involving a chain in the base sequence of DNA?
You might be referring to point mutation. This is when one nucleotide in a gene is changed and causes many irregularities in the cell.
Mutation that occurs when a single base is added or deleted from DNA causes a shift in the reading of codons by one base?
Frameshift Mutation
A involves the addition or deletion of a single base in a DNA molecule.?
A Frameshift mutation
