How many standard λ-phage vectors carrying 20kb DNA fragments or YACs carrying 250 kb DNA fragments are theoretically required to constitute a complete C. elegans genomic library?
-
- 500 λ-phage vectors or 40 yeast clones
- 400 λ-phage vectors or 5000 yeast clones
- 5000 λ-phage vectors or 400 yeast clones
- 5 × 104 λ-phage vectors or 4000 yeast clones
Correct Option: C
| Number of λ-phage vectors = | = 5 × 103 | |
| 20 × 103 |
| Number of yeast clones = | = 400 | |
| 250 × 103 |
