A relationship between two species which both
species benefit from e.g. cellulose-digesting
bacteria that live in cows’ guts.
Two reasons for using genetic
modification:
Parasite


A relationship between two species from which
one species benefits whilst the other species
neither suffers or benefits e.g. sticky seed pods
sticking to other animals’ fur.

6. The two
techniques used
to identify if the
probe has bound
are
•
Blood clotting
at injury sites
•
5. If the probe
sticks to the
patient’s DNA, this
means that….
2. DNA is
extracted from the
cells. The DNA is
chopped up using
__________ and
the DNA double
strands are
separated by
______________.
4. The DNA
________ is
mixed with the
___________
stranded DNA.
3. A DNA ______
is made that has
matching bases to
the allele that is
being tested for.
Fill in the table below to show the differences between blood groups and the implications for blood
