If the template strand of DNA carries the code: GGT-AAT-ACT, then what is the corresponding mRNA code? Recall that DNA does not use "U" as a base. Enter your answer below using the same format as shown here (three capital letters for each codon, separated by a single dash, no spaces, repeat for each codon).

Suppose that there is a protein consisting of two polypeptide chains with the given sequences in the picture.   Before performing Edman sequencing method, it is required to identify the protein's amino acid composition first. Explain why it is required to do the said step first before doing Edman sequencing method.

The following is a prokaryotic DNA sequence. Fill in the other strand of DNA. Be sure to label the ends appropriately (5’ and 3’). Transcription goes from left to right and stops after the right most base pair. On your DNA, indicate which is the coding/partner and which one is the template. Write out the pre-mRNA transcript.
