Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.

The density is the relation mass/volume.
Then you can modifiy the density of a material by either affecting the mass or the volume.
If you increase the volumen while keeping the mass constant, the density will decrease (because you are increasing the denominator of the fraction).
Also, you can decrease the mass while keeping the volume constant to decrease the density (because you are decreasing the numerator of the fraction).
Then the answer is decrease the mass or increase the volume, while the other is kept constant.
