(1). What are the structures and functions of eukaryotic chromosomes? How many chromosomes do human cells have? According to our textbook, Life: The Science of Biology , eukaryotic chromosomes are highly complex structures. Many of its features essentially are for the purpose of facilitating cell division, especially given the proteins that become attached to the chromosome, which serve as connection points for organelles (e.g., microtubules) or help condense the DNA molecule into a very small structure. For this discussion thread response, I will elaborate on these particular structures of the chromosome. The basis for the discussion is provided primarily by content discussed in Molecular Biology of The Cell-5 th Edition (Alberts et al., 2008). According to Alberts et al. (2008), chromosomes are defined as “threadlike structures in the nucleus of a eukaryotic cell that come visible by light microscopy as the cell begins to divide.” Furthermore, chromosomes comprise primarily deoxyribonucleic acid (DNA) and protein. Recall that DNA contains the genetic information needed to synthesize RNA
