Question:
Mitosis?
Answer:
the division of genetic material; can be broken down into 5 subphrases
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
(prophase, pro metaphase, metaphase, anaphase, and telophase)
i,- i,- i,- i,- i,- i,-
Question:
Cytokinesis?
Answer:
the process of dividing the cell's cytoplasm
i,- i,- i,- i,- i,- i,-
Question:
Origin of Replication?
i,- i,-
Answer:
located along the strands of DNA are short nucleotides; the nucleotide
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
sequence at each origin of replication encodes for a start signal at which
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
,the process of replication will be initiated by proteins that recognize and
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
bind to those sequences
i,- i,- i,-
Question:
Helicase?
Answer:
an enzyme that has the role of untwisting and separating the helix parent
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
strands at the replication fork
i,- i,- i,- i,-
Question:
Replication fork? i,-
Answer:
Y-shaped area where the DNA strands are beginning to untwist
i,- i,- i,- i,- i,- i,- i,- i,- i,-
Question:
replication bubble? i,-
Answer:
as the helices begins to separate the double strands, a visible replication
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
bubble forms that will expand as replication continues along the strand
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
, Question:
single stranded binding proteins?
i,- i,- i,-
Answer:
act as a wedge to keep the parent strands separated and stabilized
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
Question:
topoisomerase?
Answer:
in the front of the fork and its function is to break the hydrogen bonds
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
and the nucleotide bases and it plays a role in rejoining the DNA strands
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
when replication is complete; it is able a stabilizing enzyme that reduces
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
the strain in the strands that occur during replication
i,- i,- i,- i,- i,- i,- i,- i,-
Question:
What are the 2 phases of the cell cycle??
i,- i,- i,- i,- i,- i,- i,- i,-
Answer:
Interphase and Mitotic phase i,- i,- i,-
Question:
What does interphase consist of??
i,- i,- i,- i,-
Answer:
G1, S, G2
i,- i,-
