centromere
Two pairs of chromatids lying side by side are referred to as a tetrad.

A point on a segment that is halfway between the two endpoints is called the midpoint of the segment. It is the point that divides the segment into two equal parts.
Chiasmata, coz they didnt say two chromatids (most probably)

Recall the Wobble-Base - here is a Wobble-Answer: This protein disk is called the di-Chromosome Centromere assembly disk [it brings - and temporarily Locks - the centromeres of the pair of Chromosomes together].

centromere
The chromatids of a chromosome are attached at a point called the centromere. The centromere is a region where the two chromatids are closely aligned and hold together until they separate during cell division.
The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.

Centromere!
The copied sister chromatids remain attached to the centromere, which is a specialized region of the chromosome where the two chromatids are joined. This attachment is crucial for ensuring that each daughter cell receives one copy of each chromatid during cell division.
The centromere is a region of a chromosome that is typically located near the center. Its primary function is to facilitate the attachment and segregation of sister chromatids during cell division.
The site of crossing over between two non-sister chromatids is called the chiasma. It is a physical point where genetic material is exchanged during meiosis. This exchange leads to genetic recombination and increased genetic diversity among offspring.
