Chromosomes and Chromatin
Terms in this set (17)
A protein with a very similar structure to histones that are used in the nucleosomes that contain the centromere DNA
A region of DNA in each chromosome that allows the chromosome to associated with the kinetochore during mitosis
The way DNA is stored during interphase in the nucleus. Nucleosomes separated by some unwrapped DNA.
DNA molecule that store some or all of the genetic information for an organism
Reveals chromatin folding patterns in nuclei. The map shows TADs, regions that are segregated functionally.
An SMC protein. Critical for chromosome cohesion in replication and helps loop the chromatin. Concentrated at the boundaries of TADs.
An SMC protein. Critical for chromosome condensation in replication and helps loop the chromatin. Concentrated at the boundaries of TADs.
The entirety of an organism's genetic code.
Tightly packed form of DNA. Centromeres heterochromatize during mitosis?
A octagonal protein complex that is a core for DNA to wrap around, thus condensing it.
A complex of proteins associated with the centromere of a chromosome during cell division, to which the microtubules of the spindle attach.
The complex of DNA wrapped around a histone.
RNA -> DNA
Ancient proteins such as cohesin and condensin
Responsible for the preservation of the telomeres. Binds to an RNA molecule that has a complementary sequence to the overhanging DNA and uses this RNA sequence to complete the overhang DNA and keeps going. The next round of replication, DNA polymerase sees this as an RNA primer and extends it.
The end of chromosomes. Repetitive due to the activity of telomerase.
Topologically-associated domain (TAD)
A functionally-similar region of DNA that are close to each other in the nucleus.
