Respuesta
-
C's immediately 5' of guanidine
-
C's immediately 5' of adenine
-
C's immediately 3' of guanidine
-

Respuesta
- True
- False
Pregunta 10
Pregunta

Respuesta
-
De-novo methylation
-
Maintentence Methylation
Pregunta 11
Pregunta
Maintanence methylation- added to newly synthesised DNA opposite methylated groups on the parent strand
Respuesta
- True
- False
Pregunta 12
Pregunta
Clusters in the human genome are the same as in the bacterial genome
Respuesta
- True
- False
Pregunta 13
Pregunta
What is a multigene family?
Respuesta
-
Where related genes of a similar function are found together
-
Where related genes of different functions are found together
-
Related genes with similar functions
Pregunta 14
Pregunta
Gene families are orthologues of each other
Respuesta
- True
- False
Pregunta 15
Pregunta
What is a pseudogene?
Respuesta
-
An inactive gene due to faulty (partial) replication of the original
-
A mutated gene that has become non-functional
-
Slowly more mutations accumulate
Pregunta 16
Pregunta
What is the difference between a pseudogene and a processed pseudogene?
Respuesta
-
The latter has no introns or promoter
-
The former contains no introns or promoter
-
The latter can be used to create mRNA (though it's non functional)
Pregunta 17
Pregunta
Processed pseudogenes are throught to be caused by the re-integration of siRNA into the genome
Respuesta
- True
- False
