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.
Answer:
These are the basic steps of urine formation.
Explanation:
The first step comprises creating a filtrate in the glomerulus.
During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed.
Waste products will then be secreted by the tubules.
Whereas, the final stage is the conservation of water that occurs in the renal tubule.
There are four major stages in the formation of urine.

Answer:
Explanation:
nucleus: the center of the cell that contains the genetic material. The nucleus is like the "Brain" of the cell.
ribosome: is a large complex of RNA and proteins. Ribosomes are the cell structures that make protein. They are found in the endoplasmic reticulum.
endoplasmic reticulum: a network of tubular membranes in the cytoplasm. They fold protein molcules in sacs and transport these proteins in vesicles to the golgi apparatus.
Golgi Apparatus: stores and modifies proteins and prepares to transport them to different parts of the cell.
