Hierarchy is a theme of biology that we see in several different topics Genetics is one such area. Which sequence has the terms in the correct sequence from
LARGEST to SMALLEST in terms of molecular size?
A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose
B. Chromosome, Nucleotide, Genome, Gene, Deoxyribose
C. Deoxyribose, Nucleotide, Gene, Chromosome, Genome
D. Genome, Gene, Chromosome, Nucleotide, Deoxyribose

A. Genome, Chromosome, Gene, Nucleotide, Deoxyribose

Explanation:

According to this question, genetics as a branch of Biology is not exclusive of hierarchical basis. The following is an orderly sequence from LARGEST to SMALLEST in terms of molecular size:

Genome - Chromosome - Gene - Nucleotide - Deoxyribose

- The GENOME constitutes the whole genetic make up of an organism. This includes all the chromosomes contained in that organism.

- CHROMOSOME is the structure on which the inheritable unit called GENE is found.

- GENE is the molecular unit of inheritance which is made up of nucleotides.

- NUCLEOTIDES are monomers of nucleic acids made up of pentose sugar (dexyribose or ribose), nitrogenous base, phosphate group.

- DEOXYRIBOSE is a five carbon sugar that forms part of the structure of a nucleotide.

a covalent bond, specfically triple bond
