Question:

Which of the following is used extensively in biochemical and genetic work?

Options:

1. Aspergillus
2. Neurospora
3. Claviceps
4. Puccinia

Solution:

Page 24, XI NCERT. Neurospora crassa, commonly known as bread mold, is a filamentous fungus that has been extensively used in biochemical and genetic research. It has a relatively simple and well-characterized genetic system, making it a model organism for studying various aspects of genetics, including gene expression, gene regulation, mutation, and DNA repair. Neurospora has been widely used in laboratory research to investigate basic biological processes and has contributed significantly to our understanding of molecular genetics and biochemistry. Aspergillus, Claviceps, and Puccinia are also important fungi in various aspects of research, but they are not as extensively used as Neurospora in biochemical and genetic work.
