Posttranslational
The term "posttranslational" refers to modifications that occur to proteins after they have been synthesized by the cell, or produced by a gene. In other words, posttranslational modifications take place after the translation of messenger RNA (mRNA) into protein.<br><br>In molecular biology, posttranslational modifications are changes that proteins undergo to become active or functional. These modifications can affect the structure, function, location, and stability of a protein.<br><br>Some common types of posttranslational modifications include:<br><br>1. Phosphorylation: the addition of a phosphate group to a protein<br>2. Ubiquitination: the attachment of ubiquitin proteins to a target protein<br>3. Glycosylation: the addition of carbohydrates to a protein<br>4. Lipidation: the addition of lipid groups to a protein<br>5. Acetylation: the addition of an acetyl group to a protein<br>6. Sulfuration: the addition of a sulfur-containing group to a protein<br><br>Posttranslational modifications occur in various stages of protein processing, including:<br><br>1. Protein folding: the 3D structure of a protein takes shape<br>2. Protein cleavage: proteins may be cut to remove signal peptides or other unwanted regions<br>3. Protein modification: additions such as sugars, lipids, or phosphates are attached to a protein<br><br>These modifications play critical roles in protein function, stability, and degradation, and are essential for many cellular processes, including signal transduction, cell signaling, and immune response.

Postulation
The word "postulation" refers to the act of making a statement or claim, especially one that is not yet proven or accepted as true, often in a formal or official context, such as a scientific or philosophical hypothesis. It can also refer to a proposal or statement that is put forward for consideration or acceptance. For example, in a scientific paper, a researcher might make a postulation about the cause of a particular phenomenon, which would then be tested and potentially proved or disproved through further research.
Postulatum
A postulate is a statement or proposition that is considered to be self-evident or obviously true, serving as a basis for further reasoning or argument in a particular context, often used as an axiom or assumption in logic, mathematics, or philosophy.

Posture
The word "posture" refers to the position and attitude of the body, particularly the arrangement of the body in relation to gravity and the surrounding space.

It is a non-invasive, quantifiable method of examining the body's balance system. It involves the use of a posturography device, which measures the amount of time a person is able to remain stable on a known surface. Unfortunately, I couldn't find any words associated with that term.
