Chromatids connected by a centromere are called sister chromatids. At the end of cell division, sister chromatids separate and become daughter chromosomes in the newly formed daughter cells. This is the most fundamental function of chromatin: compactification of long DNA strands.
What is the relationship between chromatin and chromosomes and chromatids?
What is the difference between chromatin, chromatids, and chromosomes? Chromatin is the DNA and proteins that make up a chromosome. Chromosomes are the separate pieces of DNA in a cell. And Chromatids are identical pieces of DNA held together by a centromere.
Why is it important to keep sister chromatids together?
In cell division, after replication of the cell’s chromosomes, the two copies, called sister chromatids, must be kept together to ensure that each daughter cell receives an equal complement of chromosomes. … In higher organisms, DNA is packaged into chromosomes.
What do the two members of a homologous chromosome pair have in common?
The two members of a homologous chromosome pair have in common is that one is derived from the mother and the other is derived from the father. The maternal and paternal chromosomes in the homologous pair have the same genes in the same locus, they possibly have different alleles.
