A 'genomic library' is the term used to describe a

Options

A. collection of books about genes in DNA technology
B. collection of known DNA sequence
C. collection of genes that code for specific protein sequences
D. culture of bacteria that contain DNA fragments representing the genome of an organism

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Term 'Genomic Library':**
A genomic library is a collection of DNA fragments that represent the entire genome of an organism. It serves as a resource for studying the genes and their functions.

2. **Analyzing the Options:**
- **Option A:** "Collection of books about genes in DNA technology."
- This option refers to literature and not to actual genetic material. Therefore, it is incorrect.

- **Option B:** "Collection of known DNA sequences."
- This describes DNA sequencing rather than a genomic library. Hence, this option is also incorrect.

- **Option C:** "Collection of genes that code for specific protein sequences."
- This refers to codons and specific genes, but does not encompass the entire genomic library concept. Thus, this option is incorrect.

- **Option D:** "Culture of bacteria that contain DNA fragments representing the genome of an organism."
- This option accurately describes a genomic library, as it involves the storage of DNA fragments that collectively represent the genome of a single organism.

3. **Conclusion:**
Based on the analysis of the options, the correct answer is **Option D**, which states that a genomic library is a culture of bacteria that contain DNA fragments representing the genome of an organism.
