Which of the following correctly organizes these genetic terms in order from smallest to largest? a. chromosome, gene, nucleotide, dna b. nucleotide, gene, dna, chromosome c. dna, nucleotide, gene, chromosome d. dna, nucleotide, chromosome, gene

Nucleotide, gene, DNA, and chromosome are genetic terms organized in order from smallest to largest.

Further Explanation:

The nucleic acid is made up of nucleotides. Each nucleotide is made up of a phosphate group, deoxyribose, and a nitrogenous base. DNA has mainly four different types of a nitrogenous base;

Gene refers to the sequence of the nucleotides which mainly encode for a protein having a specific function. Allele refers to the variant type of the gene. DNA is made up of nucleotides and contains genetic information in the form of genes.

Each chromosome comprises of genes. Chromosomes are present in the nucleus and it is composed up of protein as well as a single molecule of DNA. The bunch like structures present is known as nucleosomes that are considered to be the basic unit of the DNA packaging. The histone protein makes the structural units of the nucleosome and these units bounded in the tight helical fiber.
