A mutation that alters a single amino acid within a protein can alter?

the primary, secondary, and tertiary level of a protein structure because once an amino acid is effected by a mutation in a single amino acid it ruins the entire protein on all levels

True or false a point mutation is the failure of a chromosome pair to separate during mitosis?
false, point mutation is the change in any single base within DNA at a given time.it occurs only once during a single mutation
A point mutation involves a change in an?
A point mutation is a genetic mutation when a wrong nucleotide bonded to DNA during replication. Usually, DNA polymerase can prevent that because it's an enzyme that finds the right nucleotides to bond to new DNA strands.
Why can mutation affect evolution?
Mutation is the cause of evolution. Mutation is what creates differences in individuals within a species, leading to diversion. Then "survival of the fittest" can occur.
If a mutation happens within a gene how could this alter the protein that is made by the gene?
DNA codes forproteins. So, if the DNA is mutated, it directly affects the protein. Two examples of mutations are:A point mutation. In this situation, onebase pair(A, T, C, or G) is replaced with a different, incorrect one. When this happens and the DNA is read in order to synthesize a protein, this incorrect base pair can lead to the DNA codon (set of 3 base pairs) that codes for a different base pair than it should have. This causes the protein to have one incorrect amino acid in it. Also, this mutation does not always mutate the protein because some codons code for the same amino acid.A frame shift mutation. This type is much worse. In this case, a base pair is just inserted in to theDNA sequence. When this happens, the entire sequence following it is essentially pushed over one spot. Then, each set of 3 base pairs that would code for an amino acid is shifted so that, instead, you would have something like 2 base pairs and 1 base pair from the codon next to it. This causes every single codon to mutate, which essentially leads to every amino acid being different and therefore, the entire protein being different.I hope that made sense. Diagrams help.
Why frameshift mutations have greater effect than point mutations?
A substitution mutation means that one base was copied incorrectly within a string of DNA. Since it takes three DNA bases to code for a single amino acid, only one amino acid is affected. A frameshift mutation, on the other hand, refers to an insertion or deletion of any number of DNA bases NOT divisible by three. This mutation throws off EVERY other amino acid after it and tends to be devastating. For example, if you had this sequence: actgactga, you would get three amino acids: act, gac, and tga. If you had a substitution error, it might yield cctgactga. In this case, only the first acid would be different. In the case of an insertion (one type of frameshift mutation), you might get: acttgactga. As you can see, a t-base has been added towards the beginning. in this case, you would get the amino acid sequence: act, tga, ctg. EVERY amino acid following the mutation is different from what it should be.
What is the type of mutation that causes hemophilia?
There is no single type of mutation that causes Hemophilia A. It is not the type of mutation but rather the location of the mutation within the genetic code.
True or false a point mutation is the failure of a chromosome pair to separate during mitosis?
false, point mutation is the change in any single base within DNA at a given time.it occurs only once during a single mutation
What would happen if UV exposure caused a point mutation where a single base was changed within your DNA sequence?
It would depend upon type and location of point mutation .
What is an mutation?
An Inversion mutation is a mutation that causes a reversal in the order of a segment of a chromosome within the chromosome, or a gene.
What is the mutation in hemophilia?
Hemophilia is a mutation of either of the genes that make factor VII or IX. Hemophilia A is a mutation of the F8 gene and Hemophilia B is the mutation of the F9 gene. Both of these mutations occur on the sex-linked X chromosome.
A point mutation involves a change in an?
A point mutation is a genetic mutation when a wrong nucleotide bonded to DNA during replication. Usually, DNA polymerase can prevent that because it's an enzyme that finds the right nucleotides to bond to new DNA strands.
Is poaching an egg a physical or chemical change?
It's a chemical change: heat alters the protein bonds in the egg.

What describes changes that occurs within species?
Mutation
Which sources of new alleles within a population?
