1What is a pseudogene?
- Agenes that don't function or code anymore
- Bgene that don't function but still code
- CGenes that still function but don't code
- DGenes that code and function
2What is not found pseudogenes
- Afailed duplication events
- Bgenes moved by transposition
- CDisabled genes
- Denable genes
3What is a copy of DNA that has an intron or exon inserted somewhere else in the gene
- ANormal gene
- Bnon-processed pseudogene
- CProcessed pseudogene
- DUnprocessed pseudogene
4What is mRNA taken up transposable elements and placing it back in the genome
- ANormal genes
- BNon-processed pseudogenes
- Cprocessed pseudogenes
- DUnprocessed pseudogenes
5What is the name of the process whereby large segments in the parent cell are made into single segments due to catalytic reactions
- AHomologous recombination
- BSite-specific recombination
- CTransposition
6Who discovered transposable elements?
- ABarbara McClintock
- BSir David Bruce
- CSir Elton John
- DStansis Barthanin
7What happens to corn kernel colour when the "C" gene is transposed by Ds
- AStays the same
- BPurple
- CClear= red
- DClear=purple
8When the ds interrupts the gene the protein is now produced
- AVerdadero
- BFalso
9Why would you get a spotted kernel?
- AThe corn immune cells are destroying the TE
- BThe mutant ds is transposed out of the gene causing the gene to return to normal
- CDs starts to fade
- DDs starts to become inactive
10How does the mutant ds TE arise?
- ARearrangement of C gene
- BRearrangement of Ac gene
- Cexactly the same as C gene
- Dexactly the same as Ac gene
11When are Ac/ds transposed mostly?
- AChromosome replication
- BWhen chromosomes are methylated
- CWhen chromosomes are demethylated
12What two things do you always find at the end of a transposable element?
- Ainverted repeated
- BNo repeats
- Cdirect repeats
13Which TE mechanism cuts and pastes gene into another place?
- ASimple transposition
- BReplicative transposition
- Cretrotransposition
14In which organism is simple transposition commom?
- Abacteria and eukaryotic species
- Bonly bacteria
- Conly eukaryotic cells
- DProtozoa
15Which transposition is only copy and pastes the DNA therefore two of the same DNA is found on the same gene
- ASimple
- Breplicative
- Cretro
16Which transposition mechanism uses reverse transcriptase to place mRNA back into gene
- Aretro
- Bsimple
- Creplicative
17Where are direct repeats mostly found?
- Awithin the host's DNA
- Bat the end of most TE's
18What can insertion sequences central regions do?
- Aencodes for transposase enzyme
- Bencodes for inhibitory proteins
- Cencodes for regulatory proteins
19transposase recognises direct repeats
- AVerdadero
- BFalso
20What is the function of the transposase enzyme?
- ACut between the borders of the transposon and gDNA
- BCut between the borders of the direct and indirect repeats
- CCut in the middle of the transposon
- DTo catalyse the incorporation of the transposable element into the DNA
21What is the function of composite transposons?
- AContain additional genes that are not necessary for the transposition
- BContain additional genes that are necessary for the transposition
22Which transposition type cause antibiotic resistance
- Acomposite transpostion
- Breplicative transposition
23Which mechanism uses resolvase gene
- AComposite mechanism
- Breplicative
24What is the function of resolvase?
- Aseperates cointergrant DNA into seperate structures that both have the TE
- Bseperates structures into cointergrant DNA that both have the TE
- Ccombines cointergrant DNA into seperate structures that both have the TE
- Dcombines structures into cointergrant DNA that both have the TE
25What do viral like retroelements have at both ends of the TE?
- ALong Terminal repeats
- BShort Terminal repeats
- CDirect Repeats
- DInverted repeats
26TE's are easily incorporated into methylated DNA
- AVerdadero
- BFalso
