Use in article (WP:NFCC#7) | Abortive initiation |
Purpose of use in article (WP:NFCC#8) | I want to show the mechanism of DNA scrunching, which is important to understanding abortive initiation. |
Not replaceable with free media because (WP:NFCC#1) |
No free media exists because this is not a widely known concept. |
Not replaceable with textual coverage because (WP:NFCC#1) |
The terminology used to describe DNA scrunching is already mostly abstract concepts to the average Wikipedia reader, so description of this complex mechanism by text alone is insufficient to provide understanding. |
Minimal use (WP:NFCC#3) | This is a small portion of the original image and will only be used in this single article. |
