What is a pseudogene?
Respuesta
-
genes that don't function or code anymore
-
gene that don't function but still code
-
Genes that still function but don't code
-
Genes that code and function
Pregunta 2
Pregunta
What is not found pseudogenes
Respuesta
-
failed duplication events
-
genes moved by transposition
-

-
enable genes

Respuesta
-
Normal gene
-
non-processed pseudogene
-
Processed pseudogene
-

Respuesta
-
Normal genes
-
Non-processed pseudogenes
-
processed pseudogenes
-
Unprocessed pseudogenes
Pregunta 5
Pregunta

Respuesta
-
Homologous recombination
-

Respuesta
-
Barbara McClintock
-
Sir David Bruce
-

Stansis Barthanin
Pregunta 7
Pregunta
What happens to corn kernel colour when the "C" gene is transposed by Ds
Respuesta
-
Stays the same
-
Purple
-
Clear= red
-
Clear=purple
Pregunta 8
Pregunta
When the ds interrupts the gene the protein is now produced
Respuesta
- True
- False
Pregunta 9
Pregunta
Why would you get a spotted kernel?
Respuesta
-
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
Pregunta 10
Pregunta
How does the mutant ds TE arise?
Respuesta
-
Rearrangement of C gene
-
Rearrangement of Ac gene
-
exactly the same as C gene
-
exactly the same as Ac gene
Pregunta 11
Pregunta
When are Ac/ds transposed mostly?
Respuesta
-
Chromosome replication
-
When chromosomes are methylated
-
When chromosomes are demethylated
Pregunta 12
Pregunta
What two things do you always find at the end of a transposable element?
Respuesta
-
inverted repeated
-
No repeats
-
direct repeats
Pregunta 13
Pregunta
Which TE mechanism cuts and pastes gene into another place?
Respuesta
-
Simple transposition
-
Replicative transposition
-
retrotransposition
Pregunta 14
Pregunta
In which organism is simple transposition commom?
Respuesta
-
bacteria and eukaryotic species
-
only bacteria
-
only eukaryotic cells
-
Protozoa
Pregunta 15
Pregunta
Which transposition is only copy and pastes the DNA therefore two of the same DNA is found on the same gene
Respuesta
-
Simple
-
replicative
-
retro

Pregunta
Which transposition mechanism uses reverse transcriptase to place mRNA back into gene
Respuesta
-
retro
-
simple
-
replicative
Pregunta 17
Pregunta
Where are direct repeats mostly found?
Respuesta
-
within the host's DNA
-
at the end of most TE's
Pregunta 18
Pregunta
What can insertion sequences central regions do?
Respuesta
-
encodes for transposase enzyme
-
encodes for inhibitory proteins
-
encodes for regulatory proteins
Pregunta 19
Pregunta
transposase recognises direct repeats
Respuesta
- True
- False
Pregunta 20
Pregunta
What is the function of the transposase enzyme?
Respuesta
-
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
Pregunta 21
Pregunta
What is the function of composite transposons?
Respuesta
-
Contain additional genes that are not necessary for the transposition
-
Contain additional genes that are necessary for the transposition
Pregunta 22
Pregunta

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