it is located at the center to which the chromatids or spindle fibers are attached
Centromere
each half of the chromosome joined
Chromatid
positive electrophoresis
anode
negative electrophoresis
cathode
terminal region of each side of the chromosome
telomers
protect the ends of chromosomes from becoming frayed or tangled
Telomers
it is the short arm
p Arm
it is the long arm
q Arm
also responsible for the foundation for kinetochore assembly
Centromere
centromeres are located near the chromosomes center
Metacentric
metacentric can be seen in
chromosome 1
centromeres are non-centrally located so that one arm is longer than the other
Submetacentric
submetacentric can be seen in
chromosome 5
centromeres are located near the end of a chromosome
acrocentric
acrocentric can be seen in
chromosome 13
centromeres are found at the end or telomere region of a chromosome
telocentric
