Question

Which genes are NOT encoded by the yeast Ty retrotransposon?

1. Protease
2. Capsid protein and integrase
3. Reverse transcriptase
4. Surface protein and membrane

Answer 1

The genes that are NOT encoded by the yeast Ty retrotransposon are protease and surface protein and membrane.

Step-by-step explanation:

The genes that are NOT encoded by the yeast Ty retrotransposon are:

1. Protease
2. Surface protein and membrane

The Ty retrotransposon encodes the Gag (group-specific antigen) protein, which forms a virus-like particle, the RT (reverse transcriptase) enzyme, and the Int (integrase) enzyme. These proteins are necessary for the retrotransposon to enter the nucleus and integrate into the genome. However, the Ty retrotransposon does NOT encode the protease or the surface protein and membrane.
