Detailed explanation-1: -Final answer: Genome, Chromosome, Gene, and Nucleotide is the correct order of organization of genetic material from largest to smallest.
Detailed explanation-2: -The order from smallest to largest is DNA, gene, chromosome. A chromosome is composed of double-stranded DNA molecules, which have four different types based on their bases attached. Four types of DNA include adenine (A), thymine (T), guanine (G), and cytosine (C).
Detailed explanation-3: -Three levels of structural organization of eukaryotic DNA in the cell nucleus are considered in this paper: (i) the chain of nucleosomes; (ii) the solenoidal or superbead (nucleomere) model of compactization of the nucleosomal fiber; (iii) the mode of suprasolenoidal DNP-packing–loops or domains.
Detailed explanation-4: -From smallest to largest, the order is nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell.
