Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds genetic material) as well as membrane-bound organelles.

Cell Division CHROMOSOMES. Chromosomes are structures located in the nucleus of the cell. They are made of DNA and protein. Chromosomes are long thin threads called chromatin until cell division occurs. Then they become visible as rod-like chromosomes. Chromosomes are composed of genes. All the genes of an organism make up the organism s genome.

Chromosomes Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.eBooks.igure 2: A the appearance of DNA during interphase versus mitosis. During interphase, the cell's DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a mouse cell (upper left).

The Structure of Prokaryote and Eukaryote Cells The nucleus of eukaryotic cells is composed primarily of protein and deoxyribonucleic acid, or DNA. The DNA is tightly wound around special proteins called histones; the mixture of DNA and histone proteins is called chromatin.

Biology Set 2 In prokaryotic cells, it consists of a single circular DNA molecule, so cell division is relatively simple. In eukaryotic cells, distributing the DNA into daughter cells is more complicated because the genetic info is divided among multiple chromosomes inside the cell's nucleus.

DNA in pro-/eukaryotes DNA in Prokaryotes and Eukaryotes. The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome. These chromosomes are identical and equal in number in all cells of an individual (except reproduction cells and mutated cells).

- The arrangement of DNA in the nucleus. You will recall that in eukaryotes, DNA is organised into chromosomes, each of which contains a single, very long double-stranded DNA molecule. These molecules are much longer than the diameter of the nucleus, and are packaged into the nucleus by winding around proteins known as histones58, which help to coil the DNA, as shown in Figure 12. This complex of DNA and proteins is known as chromatin59. The binding of DNA to histones is very ordered and the degree of packing varies.

Describe the Differences Between Prokaryotic and Eukaryotic Genomes. There are many differences in the composition and storage of genetic material in prokaryotes and eukaryotes. Chromosomes in prokaryotes consist of a single nucleic acid molecule which can be either DNA or RNA.There is comparatively little genetic material for example E.coli genome is 1200 micrometres while a single human chromosome is between 12000 and 73000 micrometers in size.acterial DNA is circular and forms structures called plasmids which condense into structures known as nucleoids. Eukaryotic chromosomes differ in the quantity of genetic material and its organisation.

Chromosome Eukaryotes possess multiple linear chromosomes contained in the cell's nucleus. Each chromosome has one centromere, with one or two arms projecting from the centromere. The ends of the chromosomes are special structures called telomeres. DNA replication begins at many different locations on the chromosome.

Biology Chapter 8 Quest Section 1 and 2 The centromere is the place at the center to keep the chromatids together. The chromatids are the things that have DNA. Explain at least 3 differences between a prokaryotic chromosome and a eukaryotic chromosome: Shape: Prokaryotes:Un-coiled- circular in shape Eukaryotes: Coiled- More complex, coiled up in a rod shape. Number: Prokaryotes: Only 1 Chromosome Eukaryotes: More than one chromosome. Explain the difference between autosomes and sex chromosomes: Autosomes are chromosomes that determine traits of the organism.
