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

codon ® gene ® DNA ® chromosome

gene ® chromosome ® codon ® DNA

DNA ® codon ® chromosome ® gene

chromosome ® DNA ® gene ® codon

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.

I think it should be codon, gene, DNA, and then chromosome.

codon = 3 nucleotides codes for 1 amino acid (e. g: ATG (Methionine=start codon)

gene = genes are made of codons

DNA = basically DNA is an inheritable trait that you get from your parents.

chromosomes = made of genes from your parents that can be passed on. (23 pairs of chromosomes from mom and dad)
