Answer:
The correct answer to fill in the blank is: Alphoid families.
Explanation:
Alphoid repetitive DNA is found in the centromeres. This satellite DNA constitutes an important portion of heterochromatin and consists of a large array of non-coding DNA that repeats tandemly (meaning that one gene is duplicated and can be found adjacent to the original copy).
Non-coding DNAs are DNA sequences that do not encode for any proteins.
