Question

A) Chromosome B) DNA nucleotide C) Codon D) Gene Place the components in order, from smallest to largest. A) A-B-D-C B) B-C-D-A C) C-D-B-A D) D-C-B-A

Answer 1

Answer: The correct answer is- B) B-C-D-A that is DNA nucleotide- Codon- Gene- Chromosome.

DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms. It is made up of small units called nucleotide ( which contains deoxyribose sugar, phosphate, and nitrogenous base).

A sequence of three nucleotide is called codon ( which codes for a particular amino acid).

Different codons are present in a gene, which is a segment of DNA coding for a particular protein.

Finally, genes are present on chromosome ( thread like structure composed of DNA).

Thus, option B) correctly depicts the given components in order, from smallest to largest.
