Lab #1 “Sequence, PCR amplification, and analysis of a gene encoding a designed inhibitor of SARS CoV-2 entry”.

You are working at a biotech company and have identified a protein that you and your colleagues believe inhibits SARS-CoV-2 entry. You wish to amplify the gene, sequence it, and run it on an agarose gel.

The anticipated sequence of this gene is below (5’-3’; 719 nucleotides in length):

ATG = start codon
TAA = stop codon

1. Provide sequences for two primers (forward and reverse) you would purchase in order to amplify this gene. Note: PCR primers are typically 20 nucleotides long).

2. Provide sequences for primers you would use to sequence the above gene. Note: assume that sequencing typically fails after 200 nucleotides (the polymerase sort of quits). Primers are typically 20 nucleotides long.

3. Using the PCR amplicon generated in #2, describe how you would characterize this DNA by agarose gel electrophoresis

These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.
