Concentration Calculation of the cytochrome. Concentration Calculation: Using your Trial 1 data from the procedure II and procedure III, and the known concentration of guanine (see Activity Form tab), calculate the concentration of the cytochrome c solution. Hint: See the Summary of Needed Formulas section under the Background tab and information found under the Activity Form tab.

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA

In your own words, describe what happens during the process of a) Transcription and b) Translation. In your answer make sure to include (for both processes):

 

a) What is the overall process? (2 marks)

Overall, the process of transcription involves…; The process of translation involves…

 

b) What is the purpose of the process? (2 marks)

Transcription happens because…; Translation happens because…

 

c) Detailed step-by-step description of what takes place during each process (including names and roles of all important organelles, structures, etc. involved) (10 marks)

The first step of transcription is…(continue to next steps); The first step of translation is…(continue to next steps).

 

Suggestion: Write your answer as if your instructor does not know anything about both processes. Include as many details as possible.
