Which flow chart correctly organizes the structures of heredity, from least to most complex?

A. codon ® gene ® DNA ® chromosome
B. gene ® chromosome ® codon ® DNA
C. DNA ® codon ® chromosome ® gene
D. chromosome ® DNA ® gene ® codon

Respuesta :

The answer is A. codon ® gene ® DNA ® chromosome.

Codons are base triplets (three nucleotide bases) on DNA.
Genes are sequences of DNA that typically contain the code for a particular protein. 
DNA is a two-stranded helix consisting of nucleotides.
Chromosomes consist of DNA molecule that is packaged into thread-like structure.
The structures of heredity,from least to most complex is A)codon*gene*DNA*chromosome.
