centromere
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
Double cone is two cones joined at their apex.
Two pairs of chromatids lying side by side are referred to as a tetrad.
The common point is called the intersection.
sister chromatids
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
Chiasmata, coz they didnt say two chromatids (most probably)
Sister chromatids - two copies of the same DNA joined at the centromere.
The part of a chromosome where two sister chromatids are joined together is called the centromere.
The two chromatids of a chromosome are attached at a point called the centromere. It is the point which it is attached to a spindle fiber during the process of cell division.
Because there are two sister chromatids joined at a point in the middle (the centromere).

centromere
When sister chromatids are joined together they are held together by proteins, which make up the centromere. The two chromatids together make up a chromosome.
Two sister-chromatids.Each chromatid consists of a molecule of DNA together with associated proteins. There are two DNA molecules (sister-chromatids) following the replication of DNA midway through the preceding interphase. The sister-chromatids are therefore genetically identical.chromatidschromatidsThe two identical joined chromosomes before cell division begins is called sister chromatids.
