Mutations change the order in which the organic bases are in your DNA. These bases code for proteins, and if they change, so the code changes. A change in the code can mean a different protein is made or that proteins are not made at all. The way it could stop proteins from being made is that the change could create a Stop Codon, which stops mRNA from being translated (which would then be transcribed into proteins). If it forms a Start Codon, then the wrong section of DNA could be translated and the wrong proteins be synthesised.
There is not always a change in to proteins synthesised, as for each amino acid in a protein there is more than one code. A mutation could change the code for a protein into a different code, but for the same protein. In such a case there would be no change.

What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
If one of the nitrogen bases were replaced by a different base what effect might that have on protein synthesis?
It depends. Because many amino acids have more than one codon, it may not affect the protein at all. However, if it does change the amino acid sequence, it could cause a change in the three-dimensional structure of the protein, resulting in a mutation.
Which mutation occurs when one nucleotide base in replaced with another base?
A point mutation occurs when one nucleotide base is replaced with another base. This can lead to changes in the amino acid sequence during protein synthesis, potentially affecting the protein's function.
Why is it possible for a point mutation to have no effect on an individual's fitness?
A point mutation may have no effect on an individual's fitness if it occurs in a non-coding region of the DNA or if it results in a silent mutation that does not change the amino acid sequence of a protein. In these cases, the mutation does not impact the individual's ability to survive and reproduce, so it does not affect their fitness.
Does this mutation affect the protein produced?
Mutations in DNA cause an incorrect amino acid to be used when assembling the protein. If the protein is complex, the mutation will cause a subtle failure in the process that the mutation affects. Errors in proteins due to mutations either lead to death or to a disruption of control paths, which causes illness and loss of function. But a mutation in the DNA doesn't necesarily make a difference, as more than one DNA sequence codes for the same amino acids, and if that is the case before and after the mutation, it wouldn't have any effect. However mutations can also be a good thing, as it can randomly generate a positive effect, like making enzymes for processing grass, this is the theory behind evolution
What does a point mutation cause?
A point mutation is when a single nucleotide switches from G to C or from A to T, or when a single nucleotide is deleted or inserted. It's unlikely for any single mutation to have a significant effect, but the effects that could occur could be anything, ranging from eliminating or altering protein synthesis of a particular protein to altering the regulatory function of a stretch of DNA and thereby affecting the embryological development of an organism.
What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
If one of the nitrogen bases were replaced by a different base what effect might that have on protein synthesis?
It depends. Because many amino acids have more than one codon, it may not affect the protein at all. However, if it does change the amino acid sequence, it could cause a change in the three-dimensional structure of the protein, resulting in a mutation.
What type of mutation is likely to have the least effect on an organism?
A silent mutation, where a change in the DNA sequence does not result in a change to the amino acid sequence of the protein, is likely to have the least effect on an organism. This is because the protein produced is unaffected, and therefore the organism's functioning remains unchanged.
What seems to determine the magnitude of a mutation's effect?
The location of the mutation within the genome, the type of mutation (e.g., missense, frameshift), and its effect on gene function or protein structure typically determine the magnitude of a mutation's effect. Additionally, the degree to which the mutation disrupts important cellular processes or regulatory mechanisms can also influence its impact.

If the ribosomes of a cell were destroyed what effect would this most likely have on the cell?
It wouldn't be protein synthesis.

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.
