A change in the sequence of nucleotides in DNA would be reflected in the mRNA molecule that transcribes it. The mRNA would contain the same change as the DNA molecule.

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.


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.


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 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.

What is the changes in a DNA sequence that affect genetic information?

Mutation


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 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.


A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?

The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
