Eukaryotic chromosomes are composed of which macromolecules

The eukaryotic chromosomes consists of the DNA -protein complex which is organized in a complex manner. This is done in order to compact more amount of DNA in the nucleus of the cell.

The DNA is wrapped around the protein complex known as the histone protein which is composed of 8 subunits known as histone.

Before the cells starts dividing the master control of the mitosis phosphorylates these histone proteins which allows them to connect with each other and bind the DNA tighter to form a chromosome.

The DNA itself is made of nucleic acid which states that the eukaryotic chromosome is made of Nucleic acid and protein complex.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
