BIOLOGY EXPERTS Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.

Many eukaryotic organisms are related based on the shared core characteristics and processes.

Explanation:

The following are the shared core processes shared by all eukaryotes.:

1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.

2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.  

The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the  carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
