Each of these activities is required during the process of reverse transcription to convert the single-stranded RNA genome into a double DNA copy, which in turn becomes integrated into the host chromosome of the infected cell catalyzed by a second pol gene-encoded enzyme, called integrase.everse Transcriptase. Reverse transcriptase catalyzes the formation of double-stranded deoxyribonucleic acid (DNA) from a single-stranded ribonucleic acid (RNA) genome.
Key Concepts. Enzymes catalyze reactions by lowering the activation energy necessary for a reaction to occur. The molecule that an enzyme acts on is called the substrate. In an enzyme-mediated reaction, substrate molecules are changed, and product is formed.The enzyme molecule is unchanged after the reaction, and it can continue to catalyze the same type of reaction over and over.nzymes catalyze reactions by lowering the activation energy necessary for a reaction to occur.
