Answer:
B) Both contain genetic codes based on sequences of bases
Step-by-step explanation:
DNA chemical bases are ATGC, while mRNA chemical bases are AUGC. Uracil replaces Thymine in mRNA, so your answer (option C) is incorrect. However, they are similar in that mRNA carries genetic code from DNA in a cell's nucleus to ribosomes, while DNA contains the genetic information for development and function of living things.
