centromeres
1 centromere for every pair of chromatids
A chromosome is made up of different parts: nucleotides (base pairs), sugar and phosphate (a full chromosome contains other stuff too but that is for a more complex explanation). The nucleotides are what codes for proteins, so that is the useful or 'coding' information. The sugar and phosphate form a sugar-phosphate backbone, holding all of the nucleotides together. (type base pairs into Google image to find a picture of this). A Chromosome is a long strand of these nucleotides which are held together with the sugar-phosphate backbone. IF UR TALKING ABOUT MEIOSIS then they are held together by spindle fibers.
desmosomes
Desmosomes hold a lot more than just the above together. See Gap Junctions.
It is called a chromatid.Two chromatids are hold by centromere.
No, the centromere only serves to hold two sister chromatids together.
They separate in anaphase and become chromosomes in new daughter cells

The crossing over of the chromosomes.Synapsis of Homologous chromosomes does not occur in Mitosis.In Meiosis, occurs during Prophase I along with crossing over between non sister chromatids; resulting chiasmata hold pairs together due to sister chromatid cohesion.

Ligaments hold your bones together. Ligaments are thick fibrous bands of connective tissue that will hold bones, cartilage or other structures together.
Desmosomes hold a lot more than just the above together. See Gap Junctions.
the cell to cell structures that hold the cells of the stratum spinosum together when they shrink are called desmosomes.
Connective tissue hold structures together.
It is called a chromatid.Two chromatids are hold by centromere.
