Put the central dogma of biology in the correct order of the flow of genetic information.

• DNA

• Protein

• RNA

Place the steps of translation in order from beginning to end.

• Amino acids are joined together to form a polypeptide

• tRNA molecules bring amino acids to the rRNA according to the mRNA codons

• The polypeptide grows with each amino acid until it is completed

• mRNA that left the nucleus travels to the rRNA in the cytoplasm

Place the steps of transcription in order from beginning to end.

• mRNA exits the nucleus through the nuclear pore into the cytoplasm

• DNA is separated into two strands

• RNA polymerase adds complementary RNA nucleotides

• Newly synthesized mRNA is formed
