You have constructed a DNA probe using the amino acid sequence of insulin ( a short piece of DNA carrying a label, such as radioactivity , which can hybridize with your target DNA ) to find your target gene. Explain your probe is a. single strand or double strand, and why . B. which part of the gene (intron, exon, promoter, etc..) is this probe binding to .

Design your own degradative pathway. You know the rules(organic mechanisms), and you've seen the kinds of reactions that occur in the biological degradation of fats and carbohydrates into acetyl CoA. If you were Mother nature, what series of steps would you use to degrade the amino acid serine into acetyl CoA? Need Help!!!

PLEASE BE DETAILED IN YOUR ANSWER. THANK YOU.

Basically, the code already functions properly. Could you just write in method header comments explaining what the method does and what the parameters are? Some of them are already done. Additionally could you change the variables and method names to make them more descriptive of what they're actually holding? Thank you!
