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.

A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
How does an insertion sequence cause a mutation?
In the DNA, the sequence of nucleotides determines how proteins are built, with each segment of three nucleotides encoding a single amino acid. When one nucleotide is inserted into the sequence, the whole sequence shifts, and all the triples are changed completely, which can cause detrimental mutations.
What kind of mutation is this ugu-ccg-GAA-cga to ugc-cgg-GAA-cga?
The sequence TGA-GCC-ATG-A is changed in 2 places to become TGA-GCA-CAT-GA.When one base is changed, it is called a point mutation.In this case, a GCC in the DNA has been changed to a GCA. This would mean the mRNA codon (coded for by this DNA) would change from CGG to CGU.Both of these codons code for the same amino acid - Arginine. Therefore this type of point mutation is known as a silent mutation.The extra C that appears would be called an addition mutation, which is a type of frameshift mutation.
A mutation involving a chain in the base sequence of DNA?
You might be referring to point mutation. This is when one nucleotide in a gene is changed and causes many irregularities in the cell.
The DNA sequence of a gene changed from AACTTG to AACATG. What kind of mutation occurred.?
The DNA sequence of gene that change AACTTG to AACATG are called missense mutation. This is known as a process.
When are mutations likely to occur?
A base sequence in a DNA molecule is changed

When one base is changed to another at a single position in the DNA sequence of a gene a mutation has occurred?
No that occurs all the time through translocation. It is not a mutation.
When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
If the dNA sequence Tgagccatga is change to tgagcacatga what kind of mutation has occurred?
The sequence TGA-GCC-ATG-A is changed in 2 places to become TGA-GCA-CAT-GA.When one base is changed, it is called a point mutation.In this case, a GCC in the DNA has been changed to a GCA.

What would happen if UV exposure caused a point mutation where a single base was changed within your DNA sequence?
It would depend upon type and location of point mutation .
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.
How would a protein be changed if a mutation caused a base to be added?
A mutation in which an extra nitrogen base is added is called a frameshift mutation. The rest of the sequence after the mutation will code for different amino acids, which will result in the alteration of the protein. Frameshift mutations cause severe genetic disorders.
