Which do you suppose would be more harmful A mutation that changed the nucleotide sequence of an mRNA molecule or a mutation that changed the nucleotide sequence of a DNA molecule?

A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.


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


How do you use a arithmetic sequence to find the nth term?

The difference between successive terms in an arithmetic sequence is a constant. Denote this by r. Suppose the first term is a. Then the nth term, of the sequence is given by t(n) = (a-r) + n*r or a + (n-1)*r


Why do a frame shift mutation usually cause more defects during protein synthesis that a point mutation?

A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly. Here is an example of one sentence with words of only three letters: The big red pig ate the red rag. Each word will make one amino acid and the words make a sentence that makes sense. Mutations that replaces one base for another will result in this: The beg red peg ate the red rag. This mutation can be read OK. But another type might make the sentence totally readable: The big res dpi gat eth ere dra.


How the three phas e system generate?

Three coils ( Suppose: A, B and C ) are placed at 120 degree from each other in uniform magnetic field. The coils are rotated at uniform angular speed ( Suppose: omega ) ( unit: radian per second ). Emfs are induced in each coil. As coil B is placed at 120 degree from coil A, emf induced in coil B lags behind that of A by 120 degree. If the three phase voltage are equal in magnitude, the sum of the three phase voltage is zero. This can be shown by different ways. ( e.g. Vector sum ). The order in which the voltage of the coil reaches to the maximum value is called the phase sequence. ( Phase sequence is of great importance in parallel operation of three phase transformers and alternators ). Phase sequence R-Y-B is known as the positive sequence, while R-B-Y is known as the negative sequence. Phase sequence can be checked by using phase sequence indicator. Phase sequence can be reversed by interchanging any two terminals.


Why can a mutation affect the function of protein?

Because a protein's function is dependent on is shape, and a mutation may change the composition (the sequence of amino acids) of a protein, which may in turn cause the shape of the molecule to change.


How is evolution related to other branch of science?

First of all, evolution is not a science. One of the first rules of science is observation, and no one has observed evolution. We have observed gene mutation, yes. Breeding almost any animal will show you variation and mutation. I suppose, to answer your question, evolution is a theory derivative of genetics and biology. But, evolution is a theory, it has no confirmation. It is just a theory.


In a four-stroke engine the timing gears control?

The gears keep the cam timing in sequence with the crankshaft. So the valves open when their suppose to and no damage occurs from valve to piston clearances.
