metaphase correct answerssecond phase of mitosis, during which the
chromosomes line up across the center of the cell and divide, one copy
moving to each daughter cell
anaphase correct answersPhase of mitosis in which the chromosomes
separate
move to opposite
and ends of
the cell

bacterium
uptake andby the
incorporation of exogenous DNA - one of the three ways
bacteria can
exchange
genes
, tranduction correct answersOne of the three ways bacteria can exchange
genes, isby
process the
which DNA is transferred from one bacterium to another by a
virus. It
refers toalso
the process whereby foreign DNA is introduced into another cell
via a viral
vector
.
conjugation correct answersOne of the three w ways bacteria can
exchangeproduction
involves genes = of a special pilus by one bacterium and transfer through
it of DNAbacterium,
another to requires a special gene that is usually present on
a plasmid
plasmid correct answersA separate extragenomic strand of DNA not
incorporatedown
bacterium's into ta

Can be used to repress production of a
gene
