Difference Between Dna And Chromosome Definition Structure Features Genome, genes, dna, and chromosomes. Except for certain cells (for example, sperm and egg cells and red blood cells), the cell nucleus contains 23 pairs of chromosomes. a chromosome contains many genes. a gene is a segment of dna that provides the code to construct a protein or rna molecule. the dna molecule is a long, coiled double helix that resembles a spiral staircase. The dna double helix (gray) is wrapped around a core particle of histone proteins (colored) to create the nucleosome. nucleosomes are spaced roughly 200 nucleotide pairs apart along the chromosomal dna. (reprinted by permission from k. (more ) life depends on the ability of cells to store, retrieve, and translate the genetic instructions. Chromosomes and genes. figure 9.3.4 9.3. 4: graphic decomposition of a chromosome (found in the cell nucleus), to the bases pair of the dna. chromosomes are located in the nucleus of the cell. a duplicated chromosome has two chromatids, double helix dna is wrapped in histone proteins to form nucleosomes.
