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

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.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
