If a strand of DNA with the sequence TGA mutated to GCA would it be a silent or missense mutation?
Both a silent and missense mutation is a change in one nucleotide. However, a silent mutation still codes for the same amino acid, but a missense mutation codes for a different amino acid. This means that a silent mutation will have no affect on the resulting protein, but a missense mutation will. Still, it is not guaranteed that a a missense mutation will result in a disfunction of created protein, as long as it is not occurring in the activation site.
Why is point mutation dangerous?
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.
Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
What would be the effect of a mutation that changed the c of the anticodon to a g?
The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
Is pku a point shirt or a frameshift mutation?
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.

A part of an mRNA has the sequence CCG. which change to this sequence would indicate a missense mutation?
CGG GAA
What One example of a mutation that would not affect an organisms phenotype?
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.
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.
Which mutation would not change the remainder of the reading frame of a gene sequence that follows the mutation?
The answer is easy.
What would have a bigger effect on organism an error during transcription or a missense mutation?
IF only you weren't here for apex! you're welcome for making your day!
What could happen to DNA that would cause a change in trait or a new trait to be expressed?
That would be a mutation. There are several types of mutations such as silent, nonsense, missense mutations along with inserstions, deletions and amplifications
What is point mutation substitution?
When a nitrogen base is substituted for a different one so it may code for a different amino acid. Sometimes substitution still codes for a same amino acid, in which case it becomes a silent mutation, but in other times it may alter the protein entirely.

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 .

The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
