Primary-secondary constrictions of a chromosome
Name the primary and secondary constrictions of a chromosome? Also name the other name provided to the secondary constriction?
Primary constriction is the narrower area of a condensed chromosome where the centromere, the structure which unites similar chromatids, is situated. Secondary constriction is an area similar to the primary constriction, much narrower than the normal thickness of the chromosome too, and in common it is associated to genes which coordinate the development of the nucleolus and control the ribosomic RNA (or rRNA) synthesis. For this cause the secondary contrictions (which can be one or more in chromosome) is termed as nucleolus organizer region (or NOR).

Just-In-Time (JIT): It is an inventory strategy companies use to raise efficiency and reduce waste by receiving goods only as they are required in the production process, thus reducing inventory costs.
Alignment Evaluation: This is the final step of sequence alignment. By comparing the alignment of sequences and alignment of their 3D structures we can assess its accuracy. This is possible of course only when we are working with family of proteins fo
