Frage 7
Frage
What happens to corn kernel colour when the "C" gene is transposed by Ds
Antworten
-
Stays the same
-
Purple
-
Clear= red
-
Clear=purple
Frage 8
Frage
When the ds interrupts the gene the protein is now produced
Antworten
- True
- False
Frage 9
Frage
Why would you get a spotted kernel?
Antworten
-
The corn immune cells are destroying the TE
-
The mutant ds is transposed out of the gene causing the gene to return to normal
-
Ds starts to fade
-
Ds starts to become inactive
Frage 10
Frage
How does the mutant ds TE arise?
Antworten
-
Rearrangement of C gene
-
Rearrangement of Ac gene
-
exactly the same as C gene
-
exactly the same as Ac gene
Frage 11
Frage
When are Ac/ds transposed mostly?
Antworten
-
Chromosome replication
-
When chromosomes are methylated

-
only bacteria
-

Cut between the borders of the transposon and gDNA
-
Cut between the borders of the direct and indirect repeats
-
Cut in the middle of the transposon
-
To catalyse the incorporation of the transposable element into the DNA
Frage 21
Frage
What is the function of composite transposons?
Antworten
-
Contain additional genes that are not necessary for the transposition
-
Contain additional genes that are necessary for the transposition
