What are the 2 phases of the cell cycle?
Answer: Interphase and Mitotic phase.
What does interphase consist of?
Answer: G1, S, G2.
What are G1 and G2 phases?
Answer: The gap phases characterized by cellular growth, such as protein
and organelle production.
What happens during the S phase?
Answer: The chromosomes are duplicated, and essential DNA information
is replicated to be passed on to daughter cells during mitosis.
What is mitosis?
Answer: The division of genetic material, which can be broken down into 5
subphases: prophase, pro metaphase, metaphase, anaphase, and telophase.
What is cytokinesis?
Answer: The process of dividing the cell’s cytoplasm.
Origin of Replication -ANSWER✔✔located along the strands of DNA are short
nucleotides; the nucleotide sequence at each origin of replication encodes for a
, start signal at which the process of replication will be initiated by proteins that
recognize and bind to those sequences
Helicase -ANSWER✔✔an enzyme that has the role of untwisting and separating
the helix parent strands at the replication fork
Replication fork -ANSWER✔✔Y-shaped area where the DNA strands are
beginning to untwist
replication bubble -ANSWER✔✔as the helices begins to separate the double
strands, a visible replication bubble forms that will expand as replication continues
along the strand
single stranded binding proteins -ANSWER✔✔act as a wedge to keep the parent
strands separated and stabilized
topoisomerase -ANSWER✔✔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
RNA primers -ANSWER✔✔complementary to the parental DNA strand
RNA -ANSWER✔✔single-stranded and contains sugar ribose and it does NOT
have a thymine but a uracil
primase -ANSWER✔✔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 the parent
