how do DNA, genes, chromosomes and genomes relate to one another?
Answer. A chromosome is formed by the aggregation of the chromatin. Chromosomes are best seen in the metaphase stage of mitosis.
Each chromosome has a centromere in the center that holds the chromatids.
Chromosomes have genes on them at a specific loci that controls the heredity.
Genes contain double helical DNA, the latter is the heredity material of the cell.
All the genes present in the nuclear material are generally referred to as the genes(nuclear material of diploid cell).
The genetic material in a haploid cell is known as genome.
To summarize, chromosomes have genes that contain DNA.
