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.

What do gene mutations provide for a population?
A mutation is a change in the genetic code of one allele of your genetic code. ( rarely does mutation affect both alleles ) Most mutations are neutral, some are deleterious, but sometimes a mutation in the germ line can convey some slight advantage to progeny. An example of this is lactose tolerance in some peoples of the world.
Difference between body cell mutation and sex cell mutation?
A mutation in a sex cell may be passed on to an offspring. A mutation in a somatic (body) cell cannot be passed on to an offspring, but can potentially cause cancer in the person who has the mutation.
The ability to cause change?
energy is the ability to cause change or do work
Do all mutations in DNA coding for mrna cause a change in an organism?
No. Some mutations can be silent, meaning that they have different codes yet it produces the same protein. If it is a mutation for the start of a mRNA sequence, then the polypeptide will just be discarded if there is no AUG.
Least important function of proteins?
Funny cause I actually had this question on my IB biology test today. The least important function of proteins is hormones at least out of the choices on my test.
What effect does a mutation have on DNA and proteins?
It will change the order of bases:) could cause diseases such as; Cystic Fibrosis
What makes proteins accurate?
The proteins are coded in DNA. So the gene expression cause RNA and proteins in solely depend on message in DNA. When there is accuracy in DNA (without any mutation), there will authentic proteins. If any change occurs in the DNA sequence that may form premature or dysfunctional proteins due to the change in amino acids.
What type of mutation is the most significant effect on protein synthesis?
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.

In your own words write a definition for the word mutation?
mutation: a change in the sequence of DNA to cause a unusal trait
A change in the genetic material of a cell is called?
Cancer- certain mutations (changes) in a cell's genetic material may cause that cell to reproduce with out control.
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
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.
How a mutation during replication can affect a protein that is synthesized?
A mutation during replication can affect a protein that is synthesized in a variety of ways. Mutations can mess up the protein sequences and cause different proteins to be synthesized.
How can a single point mutation cause a change in the amino acid?
Be cuz he has a lumpy tummy.
How can a mutation in a gene cause a change in a organism's phenotype?
Mutations can cause a cell to produce an incorrect number of proteins during protein synthesis and the phenotype of the organism would be different from what it normally would have been. Some examples are when a cat has 6 toes or a lemur has white fur.
