DNA is shaped as a double helix and is made up of nucleotides. Hope this helps! Yet, (and I'm only guessing,) the order of size you found out probably refers to the total amount of DNA in a cell, which consists of all 46 chromosomes (in humans, I mean). This gives 46 chromosomes in total. The longest chromosome is chromosome 1, with 300 million bases (approximately 10 percent of the human genome), and the shortest is chromosome 21, with 50 million bases. Ordering the terms: chromosome is the location of many genes. genes are made of DNA. So, the over all size (smallest to largest) order is: DNA< gene < chromosome. Although the carefully unwound chromosomal DNA is longer than its chromosome. These tables give the total number of chromosomes (including sex chromosomes) in a cell nucleus. Clearly, the small core chromosome 12 is mitotically quite stable and conserved during evolution, even though it is dispensable for growth, pathogenicity and the utilization of most carbon sources tested. Further, the chromosome in a cell is never alike in size, some may be exceptionally large and others may be too small. For example, most eukaryotes are diploid, like humans who have 22 different types of autosomes, each present as two homologous pairs, and two sex chromosomes. Genes are made up of DNA. The range of centromeric index was 26â50 and the variation in total length of chromatin was reported to be 3.43 to 9.86. (q) arm. 2019).
