You are right.and base has four parts:adenine, thymine,cytosine,guanine. And sugar includes pentose sugar, deoxyribose sugar.
Mitosis is a continuous process.1.Chromosomes replicate to become double-stranded.2.Double-stranded chromosomes become visible.3.Double-stranded chromosomes line up along the equator the cell.4Thechromosomes move to opposite ends of the cell.5.Two nuclei from, each with the dipped number of chromosomes.
Genes are sections of DNA.Each chromosomes can have over 1000genes.Different between one gene from the next.Order of bases along the DNA stand.Length of the DNA strum.
