Practice questions testing deep understanding of DNA replication, transcription, and translation.
Q1. During DNA replication, one strand (the leading strand) is synthesized continuously, while the other strand (the lagging strand) is synthesized discontinuously in small fragments (Okazaki fragments). Explain the specific biochemical limitation of the enzyme DNA Polymerase that forces this to happen.
Q2. In the lac operon of E. coli, what exactly happens at the molecular level when lactose is introduced into the bacterial environment? Describe the interaction between lactose, the repressor protein, and the operator region.
Q3. Assertion (A): The genetic code is described as "degenerate." Reason (R): There are 64 possible codons but only 20 amino acids, meaning that some amino acids are coded for by more than one codon.
