Frage 1
Frage
What is a genome?
Antworten
-
A little creature possessing telepathic powers
-
An organism's entire genetic material
-
The entire genetic material for one gene
-
The nucleotide sequence of the introns
Frage 2
Frage
Why is it useful to determine the proteomes of simple organisms?
Antworten
-
To create better vaccines
-
To allow monitoring of pathogens in outbreaks of disease
-
So that we can alter our own genetics to make these proteins
-
To learn more about introns
Frage 3
Frage
Why is it hard to translate the genome of complex organisms into their proteomes?
Antworten
-
They have large sections of non-coding DNA
-
Their mRNA is hard to extract
-
They contain complex regulatory genes
-
Some genes are switched off so not all the possible proteins are made
Frage 4
Frage
What are the benefits of the new sequencing methods compared to the original method devised by Frederick Sanger?
Antworten
-
They are automated
-
They are done on a much smaller scale so they are faster
-
They cost less to do
-
They involve less chemicals
Frage 5
Frage
Because DNA is [blank_start]universal[blank_end], the recipient of recombinant DNA does not have to be of the same species as the donor.
Antworten
-
universal
-
complementary
-
degenerate
-
antiparallel
Frage 6
Frage
Making 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.
Antworten
-
reverse transcriptase
-
a restriction endonuclease
-
DNA ligase
-
DNA polymerase
-
cDNA
-
tRNA
-
rRNA
-
miRNA
Frage 7
Frage
[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.
