Answer:
Chromosomes
Explanation:
DNA is packed with help of packing proteins such as histone into the compact form so as to get accommodated into the nucleus. The thread-like structures formed by DNA and the packing proteins are called chromosomes. Chromosomes are visible during cell division only.
In a resting cell, chromosomes are present in the form of decondensed indistinct chromatin. Each unreplicated chromosome has a single chromatid and two arms that are held together by a centromere.
