Mr 10 Vi Differences Betwixt Centromere Too Kinetochore

Chromosome is the construction formed past times the condensation of chromatin during jail mobile telephone division. It consists of long deoxyribonucleic acid strand wrapped only about histone proteins. Each chromosome has a primary constriction indicate called the centromere, which divides the chromosome into ii sections, or “arms.” The brusk arm of is labeled the “p arm” in addition to the long arm of the chromosome is called the “q arm.”

Electron microscopic studies of the centromeric portion revealed the presence of a poly peptide complex only about the centromere called kinetochore. Kinetochore is the poly peptide complex associated alongside the centromeric regions of mitotic in addition to meiotic chromosomes. Microtubules attached to the kinetochore during jail mobile telephone division.

Centromere vs Kinetochore

Centromere	Kinetochore
It is the primary constriction of the condensed chromosome.	Kinetochores are disc shaped poly peptide complexes intimately associated alongside centromere.
Centromeres are clearly visible alongside a low-cal microscope equally a constricted portion on the condensed chromosome	Kinetochrores tin forcefulness out alone last seen using electron microscope
It is the site of kinetochore assembly	It is the site of assembly in addition to disassembly of microtubules
It is made upwards of  highly repetitive, condensed AT rich, heterochromatic deoxyribonucleic acid alongside non-histone proteins	Made upwards of multiple proteins. It has a trilaminar structure. The inner layer is inwards closed contact alongside condensed centromeric heterochromatin. Microtubules are attached to the outer layer. The middle layer is less dense.
Fibrous corona similar construction is absent. It is made upwards of highly condensed repetitive deoxyribonucleic acid alongside some proteins	Fibrous Corona: In the absence of microtubules, a meshwork of fibers, termed the fibrous corona, tin forcefulness out last seen to extend from the surface of the outer plate. . The fibrous corona in addition to the outer plate incorporate the bulk of the known Microtubule-interacting proteins (CENP-E, dynein etc) equally good equally checkpoint proteins (Bub1, Mad2 etc) that monitor the integrity of kinetochore attachments.
Functions of Centromere: Control locus of chromosome segregation during mitosis in addition to meiosis   t is the site of kinetochore assembly It ensures delivery of ane re-create of each chromosome to each miss at jail mobile telephone division. Learn more: Chromosome morphology Chromosome number Chromosome ultra structure	Functions of Kinetochore: Kinetochore is the attachment site for spindle microtubule thereby bespeak involved inwards the drive of chromosomes during mitosis in addition to meiosis.  It is the site at which motors generate forces to ability chromosome movement. It specifies the attachments betwixt the chromosomes in addition to microtubules of the spindle thence essential for accurate chromosome segregation. Unattached kinetochores are equally good the signal generators for the mitotic checkpoint, which arrests mitosis until all kinetochores accept correctly attached to spindle microtubules, thereby representing the major jail mobile telephone wheel command machinery protecting against loss of a chromosome
