The molecules produced containing the majority of the 14 C atom that was added to support oxidative phosphorylation. Introduction: Isotopes are different forms of an element that have the same number of protons but have different numbers of neutrons and therefore they vary from each other in atomic mass. Some isotopes called as radioactive isotopes show tendency of decay or loss of subatomic particles and energy from their nuclei. The 14 C is the abundant carbon isotope of atmosphere found mostly in the oceans. 14 C reacts rapidly with the carbon monoxide that further formulates to the radioactive carbon dioxide and can be easily dissolve in ocean water.

Summary Introduction

To determine: The position of radioactive ¹⁴C present in the keto group of oxaloacetate after one turn of the citric acid cycle.

Introduction: Citric acid cycle or Krebs cycle takes place in all aerobic organisms and is a series of chemical reactions in which NADH and FADH₂ are generated. These by-products can be used in the process of oxidative phosphorylation to produce ATP.

Overview of Transformation Protocol -Prepare competent bacteria for transformation: Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes. Incubate both tubes in a 37 C water bath for 5 minutes. Questions: 1)What is the selectable marker in this experiment? How…
