Fragen in diesem Quiz (7)

  1. 1What is a genome?
    1. AA little creature possessing telepathic powers
    2. BAn organism's entire genetic material
    3. CThe entire genetic material for one gene
    4. DThe nucleotide sequence of the introns
  2. 2Why is it useful to determine the proteomes of simple organisms?
    1. ATo create better vaccines
    2. BTo allow monitoring of pathogens in outbreaks of disease
    3. CSo that we can alter our own genetics to make these proteins
    4. DTo learn more about introns
  3. 3Why is it hard to translate the genome of complex organisms into their proteomes?
    1. AThey have large sections of non-coding DNA
    2. BTheir mRNA is hard to extract
    3. CThey contain complex regulatory genes
    4. DSome genes are switched off so not all the possible proteins are made
  4. 4What are the benefits of the new sequencing methods compared to the original method devised by Frederick Sanger?
    1. AThey are automated
    2. BThey are done on a much smaller scale so they are faster
    3. CThey cost less to do
    4. DThey involve less chemicals
  5. 5Because DNA is [blank_start]universal[blank_end], the recipient of recombinant DNA does not have to be of the same species as the donor.
    1. Auniversal
    2. Bcomplementary
    3. Cdegenerate
    4. Dantiparallel
  6. 6Making DNA fragments from mRNA
    1. Extract target mRNA molecules from a cell that produces the required protein.
    2. Mix the mRNA with free DNA nucleotides and [blank_start]reverse transcriptase[blank_end].
    3. The mRNA is used as a template for new strands of [blank_start]cDNA[blank_end] to be synthesised that are complementary to it.
    1. Areverse transcriptase
    2. Ba restriction endonuclease
    3. CDNA ligase
    4. DDNA polymerase
    5. EcDNA
    6. FtRNA
    7. GrRNA
    8. HmiRNA
  7. 7[blank_start]Restriction Endonucleases[blank_end] digest the DNA at specific [blank_start]recognition[blank_end] sequences. These sites are special because they are [blank_start]palindromic[blank_end], meaning that they consist of [blank_start]antiparallel[blank_end] base pairs.
    Some types of this enzyme cut the DNA so that small tails of unpaired bases are created at each end of the fragment. These are called [blank_start]sticky[blank_end] ends and can be used to [blank_start]anneal[blank_end] DNA fragments together as long as the ends are complementary.
    1. ARestriction Endonucleases
    2. BReverse Transcriptases
    3. Crecognition
    4. Dpalindromic
    5. Eantiparallel
    6. Fsticky
    7. Gblunt
    8. Hanneal
    9. Irecconect
    10. Jdigest
