BIOD 102 PORTAGE LEARNING EXAM QUESTIONS
AND 100% CORRECT ANSWERS (LATEST 2025)
What are the 2 phases of the cell cycle?
Interphase and Mitotic phase
What does interphase consist of?
G1, S, G2
G1 and G2
the gap phases that are characterized by cellular growth such as protein and organelle
production
S phase
the time during which chromosomes are duplicated and essential DNA information is replicated
to be passed to daughter cells during mitosis
Mitosis
the division of genetic material; can be broken down into 5 subphrases (prophase, pro
metaphase, metaphase, anaphase, and telophase)
Cytokinesis
the process of dividing the cell's cytoplasm
Origin of Replication
, 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
an enzyme that has the role of untwisting and separating the helix parent strands at the
replication fork
Replication fork
Y-shaped area where the DNA strands are beginning to untwist
replication bubble
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
act as a wedge to keep the parent strands separated and stabilized
topoisomerase
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
complementary to the parental DNA strand
