Describe the structure of tRNA and explain how that structure is related to its function. Describe the structure and function of platelets by discussing a clinical disorder associated with these cells. What is the function of the blood components thrombocytes?
This is the theory that as a precursor to life, RNA acted as the molecule that completed cellular work within cells. This would hypothetically be the pre-curser to DNA, or any proteins. Because of the activity seen with ribosomes, tRNA, and others, this ...
