Options

A. Cairms, Bacteriophage
B. Cairms,Faba beans
C. Taylor et.all, Vicia faba
D. Taylor, E.coli

Answer

To answer the question "________ proved semi-conservation mode of chromosome replication in______," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Scientist**: The question requires us to identify the scientist who proved the semi-conservative mode of chromosome replication. According to the information provided, the scientist who conducted the relevant experiment is Taylor et al.

2. **Identify the Organism**: Next, we need to identify the organism in which this semi-conservative replication was demonstrated. The transcript mentions that the study was conducted on a plant called Vicia faba.

3. **Formulate the Answer**: Now that we have both the scientist and the organism, we can fill in the blanks in the question. The complete answer would be: "Taylor et al. proved semi-conservation mode of chromosome replication in Vicia faba."

### Final Answer:
**Taylor et al. proved semi-conservation mode of chromosome replication in Vicia faba.**
