B)Homologous chromosomes
C)Daughter chromosomes
D)Kinetochores

Question

Quizplus · Accepted Answer

The two copies of each type of chromosome found in normal somatic cells are called homologous chromosomes. This is because they carry the same genes but may have different versions of those genes (alleles). Sister chromatids, on the other hand, are identical copies of a single chromosome that are produced during DNA replication. Daughter chromosomes are divided sister chromatids during cell division. Kinetochores are protein structures that form on the centromere of a chromosome and are important for spindle fiber attachment during cell division.
