Which was considered to be as the genetic metrial prior to the works done by Oswald Avery, Colin MacLeod and Maclyn MnCarty?

Options

A. Nucleoids
B. Nucleons
C. Protein
D. Chromosome

Answer

To answer the question of which material was considered to be the genetic material prior to the works done by Oswald Avery, Colin MacLeod, and Maclyn McCarty, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Historical Context**: Before the experiments conducted by Avery, MacLeod, and McCarty, the scientific community was trying to identify what constituted genetic material.

2. **Identify Key Experiments**: One of the pivotal experiments in this context was conducted by Frederick Griffith in 1928, which introduced the concept of a "transforming principle." However, at that time, the nature of this principle was not yet understood.

3. **Recognize the Dominant Hypothesis**: Prior to the identification of DNA as the genetic material, proteins were widely believed to be the carriers of genetic information. This was due to their complexity and variety, which seemed to be more fitting for the role of genetic material.

4. **Conclude the Answer**: Therefore, before the groundbreaking work of Avery, MacLeod, and McCarty, proteins were considered to be the genetic material.

### Final Answer:
Proteins were considered to be the genetic material prior to the works done by Oswald Avery, Colin MacLeod, and Maclyn McCarty.
