Which statement is false about the sequential theory of enzyme catalysis?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. It treats the concerted theory as a limiting simple case.

  2. It allows for a distribution of high and low affinity subunits in the same protein.

  3. It assumes more than one conformation of a particular subunit can have high affinity for the ligand.

  4. It is also called the ligand-induced theory and is more general than the concerted theory.

#Unit 3. Fundamental Processes

Using both the enzyme reverse transcriptase and radiolabeled deoxynucleotides, you make a radioactive DNA copy from an mRNA. When you hybridize that copy DNA to nuclear DNA, you find that there are seven different chromosomal positions where hybridization occurs, and there are three unhybridized loops at each of the seven positions. From this you conclude:
