Explanation:
One DNA molecule wound around molecules of protein make up a Chromosome
All the genetic information within the eukaryotic cell is preserved as helical DNA within the nucleus. This DNA is tightly wrapped around histones as chromosomes.
Further Explanation:
DNA sequences make up genes which may have various forms called alleles. DNA, which constitutes the genotype, is transcribed into mRNA and later translated into amino acids that are linked together by rRNA to form proteins that make up an organism's phenotype. Mutations in the DNA sequences affect the respective mRNA and thus the encoded protein
Spontaneous changes within the genome can occur during the phase of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.
