factors
(TFs)

wither
activate
or

of
transcription
-
ANS
RNA
polymerase
reaches
a
terminator
sequence
(Stop
codon)

decoded
and
a

Codon
-
ANS
A
specific
sequence
of

for
a
amino
acid
Amino
acids
are
-
ANS
building
blocks
of
proteins
tRNA
-
ANS
An
RNA
molecule
that
functions
as
an
interpreter
between
nucleic
acid
and
protein
language
by
picking
up
specific
amino
acids
and
recognizing
the
appropriate
codons
in
the
mRNA
Codons
allow
-
ANS
for
DNA
and
RNA
to
communicate
Gene
Regulation
-
ANS
the
process
of
turning
genes
on
and
off
Gene
Regulation
occurs
-
ANS
during
transcription

permanent
change
in
a

mutation
-
ANS
happens
in
germ
cells,
inheritable,
in
all
cells
somatic
mutation
-
ANS
A
mutation
that
occurs
in
the
body
cells
from
spontaneous
development.
Cannot
be
inherited.
Acquired
causes
of
mutations
-
ANS
•
Incorrect
copying
of
the
DNA
sequence/
Environmental
•Exposure
•Spontaneous
silent
mutation
-
ANS
alters
a
base
but
does
not
change
the
amino
acid
DNA
is
-
ANS
master
blueprint
for
human
being
Gene
-
ANS
the
basic
unit
of
inheritance
DNA
makes
-
ANS
proteins
Chromosomes
-
ANS
threadlike
structures
made
of
DNA
molecules
that
contain
the
genes
23
pairs
of
-
ANS
chromosomes
Allele
-
ANS
variant
of
a
gene
A
cell
holds
how
many
alleles
of
each
gene?
-
ANS
2,
one
from
mom
and
one
from
dad
Phenotype
-
ANS
An
organism's
physical
appearance,
or
visible
traits.
Affected
by
environment
Genotype
-
ANS
genetic
makeup
of
an
organism
locus
-
ANS
Location
of
a
gene
on
a
chromosome
Homozygous
-
ANS
An
organism
that
has
two
identical
alleles
for
a
trait
Heterozygous
-
ANS
An
organism
that
has
two
different
alleles
for
a
trait
Recessive
-
ANS
trait
of
an
organism
that
can
be
masked
by
the

of
a
trait
Dominant
-
ANS
An
allele
that
is
always
expressed Carrier
-
ANS
A
person
whose
genotype
includes
a
gene
with
disease

is
not
expressed
in
the

which
a
particular
genotype
is

in
the
phenotype
Spontaneous
mutations
are
-
ANS
mutation
that
occurs

also
express

passed
if
-
ANS
two
copies
of
an
abnormal
gene
