What else can I help you with?
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 are the bases of mRNA coded for by this section of DNA before the mutation?
The bases of mRNA coded for by a DNA segment are complementary to the original DNA sequence. If the DNA sequences are ATCG, the corresponding mRNA bases will be UAGC.
What do DNA mutations directly affect?
It will affect protein synthesis. mRNA uses DNA (a gene) as a template and mRNA is a template to join amino acids together. If the DNA sequence (gene) is changed, the mRNA will be changed, and the polypeptides will be changed - usually with harmful consequences. Proteins produce phenotypes in organisms, so a mutation in DNA causes abnormalities.
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
How can a mutation in DNA base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
How can mutation affect the mRNA?
Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.

A mutation occurs in a cell. Which sequence best represents the correct order of the events involved for this mutation to affect the traits expressed by this cell?
The correct sequence of events for a mutation to affect the traits expressed by a cell is as follows: first, the mutation changes the DNA sequence of a gene. Next, this altered DNA is transcribed into messenger RNA (mRNA). Then, the mRNA is translated into a protein. Finally, the change in the protein can lead to a modified phenotype or trait expressed by the cell.

What is physicial or chemical agents known as that can cause mutagen?
a change in the mRNA makes a mutation of the DNA
What is the changes in a DNA sequence that affect genetic information?
Mutation

No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
How is mRNA differint from DNA?
The mRNA comes into the DNA when the DNA unzips. Then the mRNA attaches to one side of the DNA, copies it down, and leaves. Remember, AT CG
Do spider monkeys have a mutation?
I believe that spider monkeys have mutations, but it does not affect them.
How can a mutation in DNA base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
What happens to a strand of DNA when there is a change in the base on the other strand?
This is called a "mutation." What ends up happening depends on where the base that changed was located. If the changed base is on the side of the DNA strand that is not used in making mRNA, there will be no difference in the final protein made whatsoever. If the mutation occurs in a part of the DNA that is not coded to make a protein (so called "junk" DNA), there will also be no change in the final protein, because there won't be a protein made. Even if the mutation occurs in a segment of DNA that eventually makes a protein, if the replacement base causes the mRNA to code for an amino acid that is similar to the original base, there will be little change. There is more to it, but that will probably suffice.
