The appropriate organizational order from smallest to largest is option b i.e. paired bases, DNA molecule, gene, chromosome, cell, arm, person
Explanation:
The correct sequence of the organization of the smallest to largest is shown as paired bases, DNA molecule, gene, chromosome, cell, arm, person.
Paired bases: The DNA molecule consists of four nucleotide bases, they are adenine, thymine, cytosine and guanine. These are attached to ribose sugar and phosphoric acid forming nucleoside triphosphate. These dNTPs form base pairs with each other in opposite strands by hydrogen bonding. The base pairing occurs between purine and pyrimidine bases as T and A, G and C.
DNA molecule: The dNTPS joined to form specific DNA sequences which encodes the protein in organism.
Gene: It is the sequence of DNA that codes for a particular protein and undergoes transcription and translation.
Chromosome: The chromosome is a thread like structure in which DNA is packaged as genetic information. The gene is a bead like structure present on chromosome.
Cell: It is the basic unit of life in which genetic information is placed in the nucleus.
Arm: It is group pf cells forming tissue and these forms organs, here arm is an organ.
Person: is made up of million of cells. These cells are grouped in tissues and tissues form organs. Group of organs make a human or person.
