Question

which flow chart correctly organizes the structures of heredity, from least to most complex?
o codon gene dna chromosome
o gene chromosome codon dna
o dna codon chromosome gene
o chromosome dna gene codon

Explanation:

A codon is a sequence of three - nucleotide bases in mRNA that corresponds to an amino - acid or a stop signal. A gene is a segment of DNA that contains the instructions for making a particular protein or RNA molecule. DNA is a long polymer of nucleotides. Chromosomes are structures made of DNA and proteins, and they contain many genes. So, from least to most complex: codon (a small sequence), gene (a segment of DNA), DNA (a large molecule), chromosome (a complex structure containing DNA and proteins).

Answer:

A. codon, gene, DNA, chromosome
