Complete the following transcription and translation based on the given DNA strand. You will need your codon chart. DNA TAC AGG CTA ATG TCT ACT mRNA AUG UCC GAU UAC AGA UGA tRNA UAC AGG CUA AUG UCU ACU Amino Acids Met Ser Asp Tyr Ser stop 16. Match the following vocabulary words to their corresponding definition. Transcription The process of mRNA creating a complementary copy of a DNA strand. Translation The process of tRNA bringing amino acids to a ribosome to create a protein. mRNA A type of RNA that relays protein making instruction from the DNA to a ribosome. tRNA A type of RNA that has amino acids attached to it. 17. Complete the table below to see what type of mutation has occurred. Do not forget to convert the DNA to mRNA before looking up the amino acid!
