What else can I help you with?
The deletion or addition of one or more nucleotides in a strand of DNA produces?
A frameshift mutation, which can lead to a shift in the reading frame of the genetic code. This alters how the genetic information is translated into proteins, potentially causing significant changes in the resulting protein's structure and function.
How many amino acids are affected by a deletion of one nitrogen base?
A deletion of one nitrogen base would result in a frameshift mutation in the DNA sequence that codes for proteins. This would likely affect all amino acids downstream of the deletion site, leading to a significant alteration in the protein's primary sequence and possibly its function.
What is the relationship between proteins and defects?
I don't have much time to answer this, but here's a quick answer. When a mutation occurs in the DNA or mRNA processing in an organism, it causes the protein to be transcribed in an abnormal form and will have an improper secondary and tertiary structure for the function it is supposed to serve. This results in a defect in the organism.
Why don't proteins function properly unless they are immersed in water?
Proteins are dependent on water to maintain their three-dimensional structure, which is crucial for their proper function. Water molecules surround proteins and help to stabilize their structure by forming hydrogen bonds with the protein molecules. Without water, proteins may denature and lose their shape, leading to loss of function.
How can mutation in DNA affect what proteins are made by the cell?
Mutations in DNA can lead to changes in the sequence of amino acids in a protein, affecting its structure and function. This can result in altered protein function, loss of function, or gain of new function, impacting cellular processes and potentially leading to diseases.

What is dominant negative mutation?
A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
What effect does a mutation have on DNA and proteins?
Mutations can alter the sequence of DNA, which can lead to changes in the structure and function of the proteins produced from that DNA. Depending on the type of mutation, it can result in a nonfunctional or altered protein, leading to various effects on the organism.

Which type of mutation causes the most change to the protein produced?
A silent mutation

When would a mutation in DNA not cause a change in how the gene is expressed or in which proteins are made?
If a point mutation occurs in a location that is not critical to the structure and function of the protein, it will not change the way the gene is expressed. Also, since most amino acids have more than one codon, if the point mutation resulted in a codon for the same amino acid without the mutation, it will not change the way the gene is expressed.
Will the protein coded by the mutated strand of DNA function differently from the original strand?
It depends on the particular mutation. Some are "silent" which means the substitution of a base actually codes for the same amino acid as the previous. In this case, the sequence and function of the polypeptide is exactly the same. If the mutation is a nonsense or missense mutation however, then the structure and function of the protein is indeed affected. A nonsense mutation results in a codon becoming a "stop" codon, thereby terminating the polypeptide prematurely. Such proteins are nonfunctional. Missense mutations result in the change in sequence of amino acids; one amino acid takes the place of another due to the changed codon. These proteins can also be non-functional, but sometimes they can function, albeit less efficiently.

What is a mutation disease?
A mutation is a permanent change in the DNA sequence of a gene. It may be a minor or a major change; and may be harmful or beneficial.RegardsTime is imaginary
What things can happen to a protein when a mutation occurs?
proteins stop being produced due to lack of DNA function
