in the front of the fork and its function is to break the hydrogen bonds and
the nucleotide bases and it plays a role in rejoining the DNA strands when
replication is complete; it is able a stabilizing enzyme that reduces the strain
in the strands that occur during replication

1 What are the 2 phases of the cell cycle? 2 lagging strand
3 topoisomerase 4 Mitosis
Don't know?
What are the 2 phases of the cell Interphase and Mitotic phase
cycle?
What does interphase consist G1, S, G2
of?
the gap phases that are characterized by cellular growth such as
G1 and G2
protein and organelle production
, the time during which chromosomes are duplicated and essential
S phase DNA information is replicated to be passed to daughter cells
during mitosis
the division of genetic material; can be broken down into 5
Mitosis subphrases (prophase, pro metaphase, metaphase, anaphase,
and telophase)
Cytokinesis the process of dividing the cell's cytoplasm
located along the strands of DNA are short nucleotides; the
nucleotide sequence at each origin of replication encodes for a
Origin of Replication
start signal at which the process of replication will be initiated by
proteins that recognize and bind to those sequences
an enzyme that has the role of untwisting and separating the
Helicase
helix parent strands at the replication fork
Replication fork Y-shaped area where the DNA strands are beginning to untwist
as the helices begins to separate the double strands, a visible
replication bubble replication bubble forms that will expand as replication
continues along the strand
act as a wedge to keep the parent strands separated and
single stranded binding proteins
stabilized
in the front of the fork and its function is to break the hydrogen
bonds and the nucleotide bases and it plays a role in rejoining
topoisomerase the DNA strands when replication is complete; it is able a
stabilizing enzyme that reduces the strain in the strands that
occur during replication
RNA primers complementary to the parental DNA strand
single-stranded and contains sugar ribose and it does NOT have
RNA
a thymine but a uracil
enzyme that facilitates the synthesis of an RNA primer by using
the unwound DNA strand as a template; it binds to the 3' end of
primase
the parent strand and begins adding complementary RNA
nucleotides as it moves toward the 5' end of the parent strand
enzymes that add nucleotides to the 3' end of the existing chain
DNA polymerase
via dehydration reactions
triphosphate tail three phosphate group; has a negative charge around it
will undergo hydrolysis reaction which splits the molecule into
pyrophosphate
two inorganic phosphates and energy is released in the process
if nucleotides can only be added to the 3' end of a parental
strand this means that the (new) complementary RNA primer
strand is being elongated in the 5' to 3' direction. ONE RNA is
leading strand
required for leading strand elongation and nucleotides are
added continuously as the replication fork progresses along the
length of the template strand.
the other template is oriented in a 3' to 5' direction. This requires
the DNA polymerase to work backward, AWAY from the
replication fork. The daughter strand that is synthesized in this
lagging strand
direction is called the LAGGING STRAND. The lagging strand
must be replicated in a series of fragments called Okazaki
fragments rather than in one continuous strand
