Find it and fix it
Correct the errors in the following statements.
Gel electrophoresis separates DNA fragments due to
size; larger fragments travel further than shorter ones.
Before gel electrophoresis, the DNA must be
split into fragments via enzymes known as
restriction exonucleauses.
In a gel electrophoresis DNA profile,
a child’s profile will show bands
entirely different to that of their
parents.
Clones are always produced by a
method of scientific intervention.
Selective breeding and gene transfer between species
are both considered to be genetic modification
Animal cell cloning only
occurs using embryonic cells.
Dolly the sheep was cloned using a process
called sex cell nuclear transfer
DNA ligase is used during gene transfer to
break open the DNA
