Antworten
- True
- False
Frage 15
Frage
What is a pseudogene?
Antworten
-
An inactive gene due to faulty (partial) replication of the original
-
A mutated gene that has become non-functional
-
Slowly more mutations accumulate
Frage 16
Frage
What is the difference between a pseudogene and a processed pseudogene?
Antworten
-
The latter has no introns or promoter
-
The former contains no introns or promoter
