Question
The Human genome is made up of approx 30,000 genes (in both mitochondrial and nuclear DNA
Answer
  • True
  • False

Question 2

Question
How do genes code more than one protein?
Answer
  • Reversed transcription
  • Gene modification
  • Differential splicing

Question 3

Question
What is the most versitile human gene?
Answer
  • The Slo gene
  • The Pap gene
  • The Hr4 gene

Question 4

Question
The human slo gene can make up to 500 different mRNA's and works in sound regulation
Answer
  • True
  • False

Question 5

Question
RNA cannot be edited after transcription
Answer
  • True
  • False

Question 6

Question
What is a common method of altering RNA?
Answer
  • Degrading cytosine to uracil
  • Degrading thymine to uracil
  • Degrading adenine to uracil

Question 7

Question
Approx 20% of cytosine is methylated
Answer
  • True
  • False

Question 8

Question
Cytosine methylation is restricted to where?
Answer
  • C's immediately 5' of guanidine
  • C's immediately 5' of adenine
  • C's immediately 3' of guanidine
  • C's immediately 3' of adenine

Question 9

Question
Methylated cytosine can spontaneously deanimate to thymine
Answer
  • True
  • False

Question 10

Question
Match the word to it's definition- where methylation is done upstream of a gene in order to pack it around the nucleosome and silence it
Answer
  • De-novo methylation
  • Maintentence Methylation

Question 11

Question
Maintanence methylation- added to newly synthesised DNA opposite methylated groups on the parent strand
Answer
  • True
  • False

Question 12

Question
Clusters in the human genome are the same as in the bacterial genome
Answer
  • True
  • False

Question 13

Question
What is a multigene family?
Answer
  • Where related genes of a similar function are found together
  • Where related genes of different functions are found together
  • Related genes with similar functions

Question 14

Question
Gene families are orthologues of each other
Answer
  • True
  • False

Question 15

Question
What is a pseudogene?
Answer
  • An inactive gene due to faulty (partial) replication of the original
  • A mutated gene that has become non-functional
  • Slowly more mutations accumulate

Question 16

Question
What is the difference between a pseudogene and a processed pseudogene?
Answer
  • 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)

Question 17

Question
Processed pseudogenes are throught to be caused by the re-integration of siRNA into the genome
Answer
  • True
  • False

Question 18

Question
Gene fragments are sections that look like incomplete genes
Answer
  • True
  • False

Question 19

Question
Assuming the squares are all repeated units, what is the image an example of?
Image:
I.E (image/png)
Answer
  • Iterspersed Repeated Intergenic DNA

Which of the following is not an Interpersed Repeated Intergenic DNA?
Answer
  • LINES
  • SINES
  • DNA transposons
  • MINES

Question 21

Question
Interspersed Repeating Intergenic DNA are DNA sections that replicate themselves as they move around the genome.
Answer
  • True
  • False

Question 22

Question
LTR's, LINE's and SINES's are transposed around the genome, how?
Answer
  • RNA
  • DNA
  • Proteins

Question 23

Question
DNA transposons also have an RNA intermediate
Answer
  • True
  • False
