We call these frameshift mutations. Since the genetic code is read in threes (codons) any sort of shift will cause the code to be incorrect.

Here is an example of one sentence with words of only three letters:The big red pig ate the red rag. Each word will make one amino acid and the words make a sentence that makes sense. But a frameshift might make the sentence totally readable: The big res dpi gat eth ere dra g.

What will happen if the earth changes rotation and revolution?

It would depend on the degree and time frame of change and how that change was brought about. The rotation of the earth is very slowly changing. It is slowing down.


Is it true point mutations that involve the insertion or deletion of a nucleotide change the reading frame of the genetic message?

Yes. Nucleotides are read in triplet code (i.e. AAA, CCC) and each set of three nucleotides represents an amino acid. Therefore if you had a line of nucleotides, and you removed or added one in the line you would be changing how the code is read. Observe if you had ACGAGUGAU. It is read as ACG-AGU-GAU - which represents threonine-serine-aspartic acid. Now, if we remove the first A, the new code is CGAGUGAU to which the reading frame is - CGA-GUG-AU. This would even change the amino acids the code was describing. It is now - Argenine-Valine and an incomplete third code.


If a g were added to the original DNA strand after third base what would the resulting mRNA lock like How would this addition affect the protein?

If a guanine (G) nucleotide were added to the original DNA strand after the third base, the resulting mRNA would have an additional guanine, changing the sequence from what it would have been. This frameshift mutation could alter the reading frame of the codons during translation, potentially leading to a completely different amino acid sequence downstream. As a result, the protein produced could be nonfunctional or have altered properties, depending on the extent of the changes caused by the addition.


Would a 3-nucleotide insertion result in a frameshift?

Yes, a 3-nucleotide insertion would typically result in a frameshift mutation because it would disrupt the reading frame of the genetic code. This can lead to a different sequence of amino acids being produced during translation and potentially alter the function of the resulting protein.

When changing bike frame do all the other materials change also?

It's not really clear what you are asking about. But you can use the same components even if the material of the frame is different. Basically you can use the same parts in a steel frame as you would in an aluminum frame - assuming the physical fit is the same.


When a nucleotide is omitted from a newly made strand of DNA would it create a frame shift mutation?

yes. Because the 1 nucleotide is not evenly divided by 3, the reading frame would not be in the same place, resulting in a new translation for the remaining sequence.

Why do you keep metal frame of a roller away from the wall corners?

However, if you were to stop there you would get a "frame effect" because the rest of your wall is to be painted with a roller, which will yield a noticeably different texture.


Which mutation would not change the remainder of the reading frame of a gene sequence that follows the mutation?

A silent mutation, where a nucleotide substitution results in a codon that codes for the same amino acid, would not change the remainder of the reading frame of a gene sequence. This is because the amino acid sequence produced by the altered codon remains the same.

Would the reading be the same if the position f the voltmeter is changed?

No, changing the position of the voltmeter in a circuit can affect the reading due to the resistance and voltage drop across different components. It's essential to place the voltmeter in parallel with the component or points being measured to get an accurate reading.
