Fungus that is extensively used in biochemical and genetic work

Options

A. Neurospora
B. Ustilago
C. Colletotrichum
D. Saccharomyces

Answer

**Step-by-Step Solution:**

1. **Identify the Fungus**: The fungus that is extensively used in biochemical and genetic work is Neurospora.

2. **Reason for Use**: Neurospora is chosen because it is easy to grow in laboratory conditions. This makes it accessible for research purposes.

3. **Haploid Life Cycle**: Neurospora has a haploid life cycle, which means that it has only one set of chromosomes. This is beneficial for genetic studies because it allows researchers to easily observe recessive traits in offspring without the complications of dominant traits masking them.

4. **Chromosome Sequencing**: The seven chromosomes of Neurospora have been sequenced, making it easier for scientists to use it as a model organism in genetic research.

5. **Gene Mutation Studies**: Researchers can induce mutations in Neurospora to study the effects on biochemical processes. If a gene that is crucial for a biochemical event is mutated, the corresponding biochemical process will be affected, allowing scientists to understand the role of that gene.

6. **Applications in Research**: Due to these characteristics, Neurospora is widely used in various research works, particularly in genetics and biochemistry.
