Final answer:
Constitutive heterochromatin in yeast and animal cells is characterized by high DNA methylation, short tandemly repeated sequences, and its location in telomeres and close to centromeres. Therefore, the correct option is B, D, C.
Step-by-step explanation:
Constitutive heterochromatin in yeast and animal cells is typically associated with features b, c, and d. First, constitutive heterochromatin has high levels of DNA methylation on cytosines, which leads to the transcriptional inactivation of genes. Second, it is composed of many, short tandemly repeated sequences. Finally, constitutive heterochromatin is primarily located at telomeres and close to centromeres. These features contribute to the compact and inactive state of constitutive heterochromatin.
