Would all insertion or deletion mutations lead to a change in the amino acid sequence?
Not all insertion or deletion mutations lead to a change in the amino acid sequence. If the number of nucleotides inserted or deleted is a multiple of three, the reading frame remains intact, potentially resulting in no change to the amino acid sequence. However, if the insertion or deletion is not a multiple of three, it causes a frameshift mutation, which typically alters the entire downstream amino acid sequence. Thus, the effect depends on the specific nature of the mutation.
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
How would the amino acid sequence produced by the mutant strand compare to the amino acid sequence produced by series 1?
The mutant strand would likely have a different amino acid sequence compared to series 1 due to the mutation in the DNA sequence. The mutant strand may result in changes in the protein structure and function if the mutation leads to a substitution, deletion, or insertion of a nucleotide in the coding region of the gene.
During the transcription of a certain protein an extra cytosine was placed into a gene region throwing off the correct amino acid sequence what type of mutation occurred?
This is an example of an insertion mutation, where an extra nucleotide (cytosine in this case) is added to the DNA sequence during transcription, causing a shift in the reading frame and resulting in a change in the amino acid sequence of the protein being produced.
What type of mutation has occurred in figure 11-4?
In figure 11-4, a frameshift mutation has occurred. This type of mutation involves the insertion or deletion of nucleotides that shifts the reading frame of the genetic code, leading to changes in the amino acid sequence of the resulting protein.
The insertion of how many nucleotides into a genetic sequence does less damage to the code than the insertion of other numbers of nucleotides?
3 cause 3 nts corresponding to an amino acid so it wont effect all the following code after insertion
How does amino acid sequence compare?
The amino acid sequence refers to the specific order of amino acids that make up a protein. This sequence determines the protein's structure and function. Changes in the amino acid sequence can alter the protein's properties and may lead to different biological effects.
How can the amino acid codon wheel be used to determine the specific amino acid sequence in a given DNA sequence?
The amino acid codon wheel can be used to determine the specific amino acid sequence in a given DNA sequence by matching the DNA codons with their corresponding amino acids on the wheel. Each set of three DNA nucleotides (codon) codes for a specific amino acid, and by using the codon wheel, one can easily identify the amino acid sequence encoded by the DNA.
How can one determine the amino acid sequence from mRNA?
To determine the amino acid sequence from mRNA, one can use the genetic code to translate the sequence of nucleotides in the mRNA into a sequence of amino acids. Each set of three nucleotides, called a codon, corresponds to a specific amino acid. By reading the mRNA sequence in groups of three nucleotides and matching them to the genetic code, one can determine the corresponding amino acid sequence.
What is the amino acid acid sequence for auguuucggacguaa?

Which amino acid is coded for by the RNA sequence CUA?
The RNA sequence CUA codes for the amino acid leucine.
How did scientists find the gene that makes insulin?
Scientists used the amino acid code to find the DNA base sequence,i.e. they worked backwards from mRNA to DNA.They figured out the DNA sequence from the amino acid sequence- APEXthey figured out the dna sequence from the amino acid sequence
