Science Homework Help

I’m working on a microbiology exercise and need an explanation and answer to help me learn.

Dr. Kenmore heard of the famous 3-line diagram of the central dogma of molecular biology that is taught at the University of Maryland and wants you to map out this four-gene operon, orfABCD as a three-line diagram and include all of the following things:

• All promoters needed for expression.
• All transcriptional stop sites that may be required
• Draw the mRNA(s) produced when these genes are expressed
• Draw all the protein(s) produced from this operon as lines

On the mRNA(s), add

• All the Ribosome Binding Site(s)
• All the start codon(s)
• All the stop codon(s)
• The 5’ and 3’ ends of the mRNA(s)

Draw the protein products of these genes, as lines, to complete the diagram.

• Label the amino-terminal and carboxy-terminal ends of each protein product.
