Based on the given situation above about Gene expression, it is considered an example of gene expression u<span>ntil the protein is trimmed, it is not useful to the cell. Therefore, the protein should not be trimmed. Hope this answers your question. Have a great day ahead!</span>
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.
C) Natural selection
When something happens in nature and something changes all of a sudden, the animals tend to adapt to what gives them more chances of survival. As a result, a large amount of the population would attempt to adapt in a way that helps them survive.
Yes because the cell that the organism is made out of is its life source. For example, bacteria is a single celled organism.
