When a addition or deletion mutation occurs, changing the reading frame.
No
"I believe there is insertion and deletion, (one kind), and substitutions. (the second kind)" This answer is incorrect, the two types of frameshift mutation are insertion and deletion, these both alter the translation reading frame. A substitution point mutation in DNA is referred to as a single-nucleotide polymorphism and does not result in any change to the translational reading frame. insections and deletions are two types of frameshift mutations
A point mutation is never a frameshift mutation because it involves the substitution of a single nucleotide for another rather than the insertion or deletion of nucleotides that would disrupt the reading frame of a gene.
Adding or subtracting just one nucleotide would cause a frame shift mutation.
If there was an extra nitrogen base in the middle of the mRNA code, it could lead to a frameshift mutation during translation. This might cause a shift in the reading frame and result in the production of incorrect or nonfunctional proteins. Ultimately, this could disrupt the normal cellular functions and lead to genetic disorders.
No
A frame-shift mutation.
Point mutations and frame shift mutations both involve changes in the DNA sequence of a gene. However, point mutations result from the substitution of a single nucleotide, while frame shift mutations occur from insertions or deletions of nucleotides, leading to a shift in the reading frame of the gene. Both types of mutations can have significant effects on the resulting protein sequence and function.

A frameshift mutation is caused by the insertion or deletion of a nucleotide in the DNA sequence, leading to a change in the reading frame of codons. This can result in a completely different protein being produced from the altered sequence, affecting the functionality of the protein.
Frame shift mutations that occur on the X chromosome and within the potion of code that controls the formation of clotting factors can cause hemophilia. Frame shift mutations are only one of many types of mutations that can cause the disorder. For hemophilia it's not so much the type of mutation but the location of the mutation within the genetic code.

A frame shift mutation is one in which the "reading frame" for protein synthesis is altered. Starting from the DNA, you have either the insertion or deletion of one or more base pairs (but not in a multiple of three). For example, onebase pairmay be inserted into the coding portion of a gene. This is transcribed into mRNA then taken to the ribosome to be "read" (translated) by the tRNA. However, tRNA has three bases on the end of it, which correspond to a specific amino acid. By adding one base into the sequence, you "shift" the reading frame by one base pair and completely change the entire remaining amino acid sequence. Note that if you were to add or subtract three (or a multiple of three) base pairs, you would not shift the frame - you would add or subtract amino acids, but the remaining ones would be the same as the original sequence.
Point Mutations always result in [causing] a frame-shift mutation so they are the same.
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.
Yes, it is acceptable to shift tenses in writing to signal a change in time frame or to differentiate between actions that occur at different points in time. This can help clarify the sequence of events and improve the flow of the narrative. Just be sure to do so deliberately and consistently to avoid confusion.
