Before cell division of somatic cells,each chromosome must be replicated.After replication,the resulting two parts of each chromosome are held together by cohesin at the centromere.These two parts are referred to as:
A)Sister chromatids
B)Homologous chromosomes
C)Daughter chromosomes
D)Kinetochores
E)Genes

Question

Quizplus · Accepted Answer

After replication, the two identical copies of a chromosome are referred to as sister chromatids. They are held together by a protein complex called cohesin at the centromere. Sister chromatids separate during cell division and go to different daughter cells. Homologous chromosomes, on the other hand, are pairs of chromosomes that carry genes for the same traits but may differ in the actual genetic information they carry. Daughter chromosomes and kinetochores are not correct terms for describing the replicated chromosomes held together by cohesin. Genes are specific sequences of DNA that code for proteins or RNA.
