Answer
-
Normal gene
-
non-processed pseudogene
-
Processed pseudogene
-

Question 4
Question
What is mRNA taken up transposable elements and placing it back in the genome
Question 5
Question
What is the name of the process whereby large segments in the parent cell are made into single segments due to catalytic reactions
Question 6
Question
Who discovered transposable elements?
Answer
-
Barbara McClintock
-
Sir David Bruce
-
Sir Elton John
-
Stansis Barthanin
Question 7
Question
What happens to corn kernel colour when the "C" gene is transposed by Ds
Answer
-
Stays the same
-
Purple
-
Clear= red
-
Clear=purple
Question 8
Question
When the ds interrupts the gene the protein is now produced
Question 9
Question
Why would you get a spotted kernel?
Answer
-
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
Question 10
Question
How does the mutant ds TE arise?
Question 11
Question
When are Ac/ds transposed mostly?
Question 12
Question
What two things do you always find at the end of a transposable element?
Answer
-
inverted repeated
-
No repeats
-
direct repeats
Question 13
Question
Which TE mechanism cuts and pastes gene into another place?
Question 14
Question
In which organism is simple transposition commom?
Question 15
Question
Which transposition is only copy and pastes the DNA therefore two of the same DNA is found on the same gene
Question 16
Question
Which transposition mechanism uses reverse transcriptase to place mRNA back into gene
Question 17
Question
Where are direct repeats mostly found?
Answer
-
within the host's DNA
-
at the end of most TE's
Question 18
Question
What can insertion sequences central regions do?
Answer
-
encodes for transposase enzyme
-
encodes for inhibitory proteins
-
encodes for regulatory proteins
Question 19
Question
transposase recognises direct repeats
Question 20
Question
What is the function of the transposase enzyme?
Answer
-
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
Question 21
Question

Answer
-
Composite mechanism
-

combines cointergrant DNA into seperate structures that both have the TE
-
combines structures into cointergrant DNA that both have the TE
