**Question:**Chargaff observed that the amount of _____ was not equal to the amount of _____ in all tested organisms.**Options:**- O A: A + G; T + C- O B: A; T- O C: purines; pyrimidines- O D: A + T; G + C- O E: G; C**Explanation:**This question relates to Chargaff's rules, which describe the quantitative relationships between certain nucleotide bases in DNA. Although early interpretations suggested equal pairing, this specific question highlights there are cases where quantities of these bases do not match in various organisms. The options represent different possible comparisons related to these rules.

Introduction: Every living thing has self-replicating genetic material called DNA. It is a…

Answered: Chargaff observed that the amount of…

A gerbil is fed a normal diet including 14C-lysine. After a period of time on this diet biopsies are taken from several tissues and analyzed for radioactivity. 14C is detected in glycogen from muscles and liver, triglycerides from adipose tissue, and nucleic acids isolated from all tissues. In as much detail as you can, show how the radioactivity from an amino acid found its way into these other classes of biopolymers. The only rule is that we can not use Lysine-pyruvate 6-transaminase in this
