Eukaryotic Chromosomes Eukaryotic chromosomes are found in the cell’s nucleus. the principal feature that distinguishes a eukaryotic cell from a prokaryotic cell is the presence of a membrane bound nucleus. this nucleus is the “control center” of the cell that stores all the cell’s genetic information, or dna. Compared to prokaryotic chromosomes, eukaryotic chromosomes are much larger in size and are linear chromosomes. eukaryotic chromosomes are also stored in the cell nucleus, while chromosomes of prokaryotic cells are not stored in a nucleus.
Eukaryotic Chromosomes During some stages of the cell cycle, the long strands of dna are condensed into compact chromosomes. there are a number of ways that chromosomes are compacted to fit in the cell’s nucleus and be accessible for gene expression. What are chromosomes? in the nucleus of each cell, the dna molecule is packaged into thread like structures called chromosomes. each chromosome is made up of dna tightly coiled many times around proteins called histones that support its structure. The genome of each eukaryotic species has a characteristic number of linear chromosomes found in the nucleus of each somatic cell; for example, humans have 46 nuclear chromosomes, mice have 40, and apples have 34. in addition, mitochondria and chloroplasts also house their own dna!. The most striking difference between prokaryotes and eukaryotes is how their genetic material is packaged, eukaryotic cells have two or more chromosomes contained within a membrane delimited organelle, the nucleus.

The most striking difference between prokaryotes and eukaryotes is how their genetic material is packaged, eukaryotic cells have two or more chromosomes contained within a membrane delimited organelle, the nucleus. Eukaryote, any cell or organism that possesses a clearly defined nucleus. the eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well defined chromosomes (bodies containing the hereditary material) are located. In eukaryotes, dna is coiled around histone proteins, forming a compact structure, whereas in prokaryotes, chromosomes are typically circular and lack histones. Eukaryotic chromosomes are organized structures found within the nucleus of plant and animal cells. these structures house the organism’s entire genetic information, encoded in long strands of deoxyribonucleic acid (dna). Eukaryotic genomes are defined by linear chromosomes contained within a membrane bound nucleus, in contrast to prokaryotic genomes, which are usually arranged as circular chromosomes within the cytoplasm.
