Human Genome
is a
complete set of nucleus acid sequences
for human.
Modified Trait
is the
introduction of new traits to an organism by making changes.
Genetic Modified Organisms
is an animal plant or microbe whose DNA has been
altered.
Detection
is the action or process of
identifying the presence of something concealed.
PCR Amplification
is a laboratory technique for
rapidly producing millions to billions of copies.
PCR
is a technique that allows the
detection of specific genes
in target organisms.
PCR SEQUENCE:
Adenine-Guanine
,
Cytosine-Thymine
Law of Segregation
:
alleles are separated due to random chance.
Law of
Independent Assortment
: alleles of two different genes get sorted into
gametes
independently.
Cambrian Explosion-
belief that here was a sudden apparent explosion of diversity in life forms about
545 million
years ago.
Molds- impression
made in
substrate
Casts-
when a
mold
is filled in
Petrified-
organic materials into stones
Original Remains-
preserved wholly iced
Carbon Film-
in
sedimentary rocks
Trace-
record the
behavior
of the organism
Relative Dating
is based upon the study of
layering
and
fossils.
Law of Superposition
:
sedimentary layers are deposited in specific time.
Law of
Original Horizontally
:
deposition of rocks
happen
horizontally tilting.
Law of
Cross-Cutting Relationship
: a fault cuts through
existing rocks.
Absolute Dating
determined the
actual age of fossil
through
radiometric dating.
Unaltered Preservation-
small organism in amber
Petrification- organic contents
of bone and wood are replaced with
silica.
Replacement-
hard parts are
dissolved
and
replaced
by other
minerals
like
iron
,
Carbonization-
other elements are removed and only carbon
remained.
Recrystallization-
hard parts are converted to more
stable minerals
Authigenic Preservation- molds
and
casts
are formed.
