What is the relationship between chromatin and chromosomes?
Chromatin is a complex of DNA and protein found in eukaryotic cells. Its primary function is packaging long DNA molecules into more compact denser structures. This prevents the strands from becoming tangled and also plays important roles in …
Chromosomes are linear arrangements of condensed deoxyribonucleic acid (DNA) and histone proteins which form a complex called chromatin. Homologous chromosomes are made up of chromosome pairs of approximately the same length centromere position and staining pattern for genes with the same corresponding loci. One homologous chromosome is inherited from the organism's …
A chromatid (Greek khrÅmat- 'color' + -id) is one half of a duplicated chromosome. Before replication one chromosome is composed of one DNA molecule. Following replication each chromosome is composed of two DNA molecules; in other words DNA replication itself increases the amount of DNA but does not (yet) increase the number of chromosomes.

It is now well-accepted that chromatin is not randomly organized in the cell nucleus but the positions of each chromosome domain relative to its neighboring domains is characteristic of different cell types and after this geography is established in each newly formed cell the chromosome domains do not move appreciably until the next cell division.
Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between proteins and DNA in the cell. It aims to determine whether specific proteins are associated with specific genomic regions suc...
